In any 6 event, if I do ask a question, you don't understand 7 what information I'm seeking, would you please let 8 me know you don't understand my question; can I 9 secure that agreement from you? 10 A Yes. 11 Q If at any time you wish to confer with your 12 counsel, Mr. Wilt, although most attorneys object 13 to that during a deposition, I do not. Simply 14 indicate for the record you wish to confer with 15 your attorney, I'll get up and leave the room, you 16 guys can work it out; do you understand that you 17 have that right? 18 A Okay. 19 Q Lastly, it's unlikely, but there may come a point 20 when I ask a question, Mr. Wilt will object. If he 21 does so, please do not answer the question on the 22 table until your attorney tells you to do so; can I 23 also secure that agreement from you? 24 A Okay. 25 Q You have just handed me your CV. It is my fault, I 0006 1 did not ask for it prior to today. We'll have the 2 court reporter mark that as Plaintiff's Exhibit 1. 3 (Plaintiff's Exhibit 1 4 marked for identification.) 5 Q I know you want to tell your life story, we're 6 going to make this part short hopefully. 7 You graduated from Case Western Reserve 8 Medical School in 1972, correct? 9 A Yes. 10 Q Following that you entered into an internship at 11 University Hospitals according to your CV from '72 12 to '73? 13 A Yes. 14 Q Surgical of course. Then '73 to '74 you were in a 15 general surgical residency at UH, correct? 16 A Yes. 17 Q Who was the chairman of the department at that 18 time, if you have a recollection? 19 A Charles Hubay. 20 Q Then you switched programs, you went over to the 21 Cleveland Clinic; is that right? 22 A Yes. 23 Q '74 to '77, correct? 24 A Yes. 25 Q Why did you -- I see. At that point did you 0007 1 determine you wanted to specialize in orthopedics, 2 is that why you transferred programs? 3 A Yes. 4 Q Who was the director of the orthopedic surgery 5 program when you were at Cleveland Clinic? 6 A Initially Roy Collins, then secondarily Allen Wild. 7 Q Subsequent to 1977 I assume that you became Board 8 certified. I see I'm correct. 9 You are Boarded, Doctor, in orthopedic 10 surgery, correct? 11 A Yes. 12 Q 1978 is what your curriculum vitae indicates. 13 Are you Board eligible in any other medical 14 subspecialties? 15 A No. 16 Q Why don't you briefly run me through your medical 17 career, beginning at the time you finished your 18 orthopedic Fellowship at the Cleveland Clinic? 19 A Pretty easy. I've been in private practice at 20 this location since 1977, doing general orthopedics 21 and a number of specialty things. Primarily 22 arthroscopy, joint replacement, the last number of 23 years, a lot of spine work. 24 Q Let me break that out for you. At the time that 25 Mr. Lasko was your patient -- he was your patient 0008 1 for a substantial period of time. In the summer of 2 1999 when he was your patient, you were a member of 3 a group called Ohio City Orthopedics, correct? 4 A Yes. 5 Q When was that entity formed, to the best of your 6 recollection? 7 A I think it was 1976. 8 Q So you've always been with Ohio City Orthopedics? 9 A Yes. 10 Q If my memory reserves me well from the days I used 11 to do plaintiff automobile work, over the years 12 there have been different combinations of 13 physicians in this group, correct, some have gone, 14 some have left? 15 A Little bit of a change. 16 Q Essentially this has always been your practice? 17 A Yes. 18 Q In the answer that you gave previously you 19 indicated that for the last several years, I'm 20 paraphrasing, you did more spine work. 21 What kind of spinal surgery do you do? 22 When did you begin doing them actively I suppose is 23 the easy way to phrase it? 24 A From the time I was in practice in 1977. I've done 25 spine work, all the cervical spine work for our 0009 1 practice. A lot of lumbar work. When instrumented 2 spine work came along, I was one that was doing 3 that. 4 Q The only reason I asked that was the way you 5 phrased it for the last several years, perhaps you 6 were trying to communicate to me you became more 7 involved in spine work in the last several years 8 than you had previously been? 9 A What's happened differently in the last few years, 10 my partners have never done anything but simple 11 diskectomies on the lumbar spine. When the newer 12 fusion techniques and instrumented techniques for 13 the lumbar spine came along, I was the only one 14 doing them. 15 Additionally there is a number of other 16 procedures on the spine, I'm the only one in the 17 group that does percutaneous, arthroscopic 18 diskectomies. I do vertebral body replacement. 19 Most of the major things that are done in spine. 20 So I would get all of their referrals. 21 In addition to that, there is a Cleveland 22 Orthopedic and Spine Hospital, that now has a 23 section on spinal surgery, which I'm one of the 24 members of. 25 Q I was going to ask you about that in a second. 0010 1 Forgive my ignorance, I don't profess to understand 2 how people become experts in their fields at 3 certain procedures. Was there a special 4 certification class or additional training past 5 your Fellowship you took to become competent in 6 fusion and instrumentation procedures, the ones you 7 are describing that your other partners don't do? 8 A For virtually every one of those things I've done, 9 except the cervical spine, I learned to do in my 10 training. All the instrumented spines and 11 techniques with the electrodes and percutaneous 12 things I have taken courses for. 13 Q The courses that you took to get you I suppose to a 14 different level of competence are not listed here 15 on your CV, correct? 16 A No. There is a huge number of courses that I have 17 had, there are too many to put on a CV. 18 Q Currently, Doctor, you have privileges at what 19 hospitals? 20 A Lutheran Hospital, Saint Vincent Charity Hospital, 21 Deaconess Hospital and Saint Michael's Hospital. 22 Q Do you perform surgeries more regularly at any one 23 of the four of those? 24 A About 90 percent of what I do has been at Lutheran 25 Hospital. 0011 1 Q The other hospitals only on occasion; is that a 2 fair statement? 3 A The other hospitals are pretty much things we get 4 through the emergency room at those hospitals, 5 consults from physicians at those hospitals. 6 Q Trauma surgery if they come in and are you on call, 7 consultations from other physicians practicing out 8 of that hospital? 9 A Yes. 10 Q I generally try to take a short deposition. I know 11 that probably shocks you, but I do. 12 Dr. Bohl, you have been sued for medical 13 negligence prior to this occasion, correct? 14 A Yes. 15 Q I don't want to know about all those cases. The 16 only thing I want to ask you is has there been any 17 other claims against you filed, I'm not talking 18 about letters of intent to sue, regarding a dorsal 19 column stimulator? 20 A No. 21 Q This is the only case that has been an issue for 22 you, correct? 23 A Yes. 24 Q Are you generally acquainted with what my 25 allegations of negligence are against you? 0012 1 A I think so. 2 Q I guess we could talk a little bit about that. I 3 like to give you a chance first before I pick 4 through the records. 5 Upon reflection, Doctor, do you agree with 6 me that in some respects the care and treatment 7 which you rendered to Jerry Lasko beginning in 8 August of 1999, continuing through September of 9 1999, did not meet the accepted standards of 10 medical care? 11 A No, not at all. 12 Q So you don't believe that there is anything which 13 you should have done differently than you did do? 14 A Not on the basis of accepted standards of medical 15 care. If you look retrospectively, you might 16 change something that did you. 17 Q We'll get into that. I wanted to see how you felt 18 about it. 19 Also I guess because I'm curious to ask the 20 question, it doesn't have anything to do with 21 medicine, Mr. Lasko seems rather fond of you, he 22 fairly communicated that to your counsel at his 23 deposition. Do you have the same feelings for 24 Mr. Lasko? He's been your patient for a pretty 25 long time, I guess I was curious? 0013 1 A Yes, I do. 2 Q Subsequent to the time Mr. Lasko had me file this 3 lawsuit, you in fact had an opportunity to 4 physically examine him; is that right? 5 A After you filed the lawsuit? 6 Q Yes. 7 A Yes, I did. 8 Q How many times have you seen him since that? I 9 don't think I have the updated portion of your 10 record. 11 MR. WILT: What date did you file 12 the lawsuit? 13 Q I filed the lawsuit February 7, 2001. 14 A Yes, I have seen him one time since then. 15 Q We will talk about that later. I do not know 16 whether or not I have your complete medical chart, 17 so let me ask this question: What is the first 18 occasion that you ever had to see Mr. Lasko as a 19 patient? 20 A I wish I could tell you. I believe it was probably 21 sometime in the late '70s. Somehow we had a large 22 number of our charts, without my permission, 23 purged. They threw out old charts. My records 24 concerning Mr. Lasko, my office records, 25 handwritten notes actually start in 1990. I had 0014 1 been seeing him at least 10 years before that. 2 Q That was my understanding. I wanted your 3 explanation on the record whey when I sent a 4 subpoena for the production of records the 5 treatment began in 1990, however you just advised 6 me somehow charts in your office got purged? 7 A Yes. 8 Q His was probably one of them? 9 A Yes. 10 Q This is a strange question to ask, do you have 11 reason to believe that there is any medical 12 information in the purged charts that would be 13 relevant to the issues that we're discussing about 14 the placement of this dorsal column stimulator? 15 A I don't think so. I'm sure there are a number of 16 his spinal surgeries and findings from them in 17 those charts. 18 Q Doctor -- 19 MR. WILT: Were you done? 20 A I don't see how they would have any relation to the 21 dorsal column stimulator. 22 Q Fair enough, so we're not worried about those 23 records being available. 24 In anticipation of today's deposition, 25 Doctor, what materials did you review? 0015 1 A My office notes, hospital records for the last 2 couple admissions, x-rays. 3 Q Did you physically look at the x-ray films? 4 A Yes. 5 Q When you say x-rays, which x-rays are you referring 6 to? 7 A The ones that were done basically on that 8 admission. 9 Q We will be able to discuss those. Did you go back 10 and look at x-rays, CT's, or MR's taken prior to 11 August 24 1999? 12 A No. 13 Q Fair enough. 14 A I may have between -- in the last year or since 15 this happened, I may have looked at them. I don't 16 recall doing that though. I didn't in order to 17 prepare for this deposition. 18 Q Do you retain those films in your office? 19 A They are normally kept down in x-ray. I happen to 20 have them signed out right now. They are in my 21 office. 22 Q For what purpose do you have them signed out? 23 A To look at them. 24 Q I was curious. 25 A Also try and organize. 0016 1 Q Fair enough. I'm assuming there is a goodly number 2 of x-rays from over the years? 3 A Yes. 4 Q Do you have any idea approximately how many x-rays 5 there are? 6 A Probably hundreds. 7 Q You didn't look at all those hundreds, did you? 8 A No. 9 Q Fair enough. Doctor, in anticipation of today's 10 deposition, did you review any medical literature? 11 A Not in preparation for today's deposition, no. 12 Q When is the first time that you, as I'll call you a 13 spine surgeon if that is okay with you, when was 14 the first time you ever inserted a dorsal column 15 stimulator? 16 A I actually didn't know. I noticed in here it was 17 about 10 years ago I first started suggesting it to 18 him. I had put in a number of them before that. I 19 would have to say more than 10 years. 20 Q I was just curious. This isn't a contest to trick 21 you, because there would be no way I would even 22 know the true answer. In the last decade, 23 approximately how many dorsal column stimulators 24 have you placed in patients? 25 A I would estimate between 20 and 30. 0017 1 Q So not a huge number, maybe two or three a year? 2 A Correct. 3 Q What is the purpose of a dorsal column stimulator? 4 A Used for people who have pain, usually lower 5 extremity or back pain, which you are not able to 6 relieve by other methods, by further surgery, or in 7 some cases the pain isn't due to a spinal problem, 8 may be due to a vascular problem, or one of my 9 recent patients had a knee operation, had a reflex 10 sympathetic dystrophy over a four year period of 11 time, couldn't be helped. The purpose is primarily 12 pain relief. 13 Q Is a dorsal column stimulator something that a 14 physician recommends when they believe that their 15 patient has intractable pain syndrome? 16 A It can be one of the things they might recommend. 17 Q Is it more or less an option of last resort in pain 18 management? If it isn't let me know, I'm curious 19 how you view them? 20 A Yes, I guess it would be. 21 Q In Mr. Lasko's case, what was the primary reason 22 you recommended this particular device for him? 23 A He had a number of spinal surgeries in his lower 24 back. There did not appear to be anything -- over 25 the years he would have an operation, he would get 0018 1 better and develop a new problem, because things 2 tend to shift up in the lower back. 3 At the point we did his dorsal column 4 stimulation there did not appear to be anything 5 further in his lower back treatable surgically, or 6 that he had a good chance of getting a good result 7 from. He had a lot of scar tissue you can't 8 correct, arachnoiditis. He had significant back 9 and leg pain. 10 Q You felt this was in his best interest, correct? 11 A I suggested it to him a number of times as an 12 option. He tried other things. This particular 13 time he decided to use this option. 14 Q Do you have a recollection, or it doesn't have to 15 be a recollection, something that you may have 16 reviewed in the last day or so, that would give you 17 some indication as to why on prior occasions he 18 declined your suggestion for this stimulator? 19 A Yes. 20 Q I can't read your handwriting. Not that it's bad, 21 I have faded copies. 22 A You can't tell from anything in the chart why the 23 reason is. 24 The reason is for a long period of time the 25 Bureau of Workmen's Compensation I believe was 0019 1 covering his injuries. Until very recently you 2 could not get approval from them to insert a dorsal 3 column stimulator. They wouldn't pay for it. 4 Q In the past you would be suggesting it, you would 5 be writing letters to the Bureau's medical review 6 committee saying I believe this is a necessary 7 medical procedure, they would say forget it, 8 Dr. Bohl, you can't do that, right? 9 A That's correct. 10 Q What would they, in lieu of a dorsal column 11 stimulator, allow you to do for the patient? 12 A They don't suggest other options. 13 Q They said no, didn't give you any medical options; 14 is that right? 15 A Yes, they had reasons for not allowing them, but 16 it's historical. 17 Q Fair enough. To the best of your knowledge, 18 although as you indicated it's not documented, 19 there was never a reluctance on Mr. Lasko's part to 20 follow your advice, simply that he couldn't get 21 approval for the procedure? 22 A Yes, initially. Then other times it wasn't 23 indicated. He had reasons that you could identify 24 why he was having the pain, such as the 25 degeneration would progress up to another level, he 0020 1 had instability and spinal stenosis at another 2 level. 3 Q Mr. Wilt asked Mr. Lasko a question at his 4 deposition, I'm not sure I know the answer because 5 of the records. How many surgeries did you perform 6 upon Mr. Lasko? 7 A Actually I don't know without his whole chart. I 8 know there were a number of surgeries on his 9 ankles. I know I operated on both of his 10 shoulders. He kept getting additional levels in 11 his neck. I honestly couldn't tell you. 12 Q None of us actually as we sit in this room today 13 know how many procedures he underwent with you; is 14 that right? 15 A No. 16 Q You are indicating in the general sense, first of 17 all you did his cervical spine, correct? I don't 18 want to say first as in time. 19 A First thing I ever did to him was a -- I believe it 20 was a decompression. His spinal cord was being 21 compressed by an old compression fracture at L-1 I 22 think. 23 Q Not to confuse the record. All I was indicating is 24 that over the period of time starting somewhere -- 25 couldn't have been before 1977, but from '77 0021 1 forward you operated on his lumbar spine, cervical 2 spine, you're today indicating shoulders and ankles 3 also? 4 A Both shoulders, both ankles, hands. 5 Q During the entire time that you treated him up to 6 the point that he arrives for the placement of the 7 stimulator on August 24th, did you ever have reason 8 to evaluate his thoracic spine? 9 A No. 10 Q Why was that? 11 A He really never had any symptoms that were 12 attributable to it. 13 Q Do you believe, based upon your review of the 14 records, it is obviously clear to me now you were 15 able to look at x-rays, that Mr. Lasko had 16 degenerative disk disease? 17 A Yes. 18 Q Through what areas of his body did he have 19 degenerative disk disease? 20 A Probably his entire spine. 21 Q Therein lies my question. I just asked you about 22 the thoracic. You are indicating that you really 23 didn't evaluate that because there were no specific 24 complaints to the thoracic spine, correct? 25 A That's correct. 0022 1 Q However, it would have been clear to you, prior to 2 the time that you took him in for the dorsal column 3 stimulator on August 24th, that did he in fact have 4 degenerative disk disease as you just testified 5 probably throughout his entire spine? 6 A Probably. But the disks in the thoracic spine are 7 usually very small, don't cause problems. 8 Q Sometimes do they cause problems however? 9 A They can. 10 Q I guess I'm going to -- before we get into that 11 issue, if you would look at your office notes. I 12 made it easy, I copied the ones I wanted to talk 13 about. 14 (Plaintiff's Exhibit 2 15 marked for identification.) 16 Q Doctor, I'm going to let you use this one for 17 reference so you don't have to dig for them, or you 18 can look at your original if it's better. I would 19 like to have read into the record what appears to 20 be your progress note of -- let me guess on the 21 date, July something 1999, where it says insurance 22 Anthem. 23 A Looks like July 7th. 24 Q Mine I can't tell what the date is. I do apologize 25 for that. Would you read into the record what your 0023 1 note of that date says? 2 A Pain worse, back left leg. Right leg gives way. 3 Discussed dorsal column stimulator. Surgery, 4 laminectomy to insert dorsal column stimulator 5 electrode 8-24-99. Surgery to implant dorsal 6 column stimulator 8-26-99. Vicodan ES number 50. 7 Q Let me ask you a couple questions about this note. 8 If it is as you indicate July 7, 1999, at 9 that point he's back in your office for 10 evaluation. Had you concluded what he was 11 suffering from was a failed back syndrome from your 12 surgery of the prior December? 13 A That is one name for it. 14 Q I don't want to give it the wrong name. What was 15 your diagnosis for your patient based upon his 16 symptoms of presentation on July 7, 1999? 17 A Well, failed back syndrome covers a lot of the 18 things he has. He was having symptoms from 19 arachnoiditis, scar tissues around the spinal 20 cord. Arthritic changes in the lower spinal cord. 21 Probably from some degenerative disk disease from 22 the disks themselves since he hadn't had anterior 23 fusions, except at a couple levels. 24 Q I hope I didn't seem like I was being difficult. I 25 borrowed that phrase because I saw it somewhere in 0024 1 your notes you were calling it failed back 2 syndrome. I was trying to identify. On this 3 particular date you didn't recognize a new 4 independent operable orthopedic problem that would 5 be accounting for the back left leg pain worse; is 6 that right? 7 A No. 8 Q Did you do any additional diagnostic testing at 9 that time to determine what the probable or 10 possible causes could have been for what he was 11 experiencing? 12 A Not on that date. 13 Q When prior to July 7, 1999 was the last time that 14 you performed an x-ray, CAT scan or MRI on 15 Mr. Lasko's spine? 16 A We had an x-ray March 26, 1999. 17 Q You had an x-ray done of his lower back; is that 18 correct? 19 A Yes. 20 Q Prior to July 7, 1999, at any time were you in 21 possession of diagnostic studies that indicated 22 that there was degenerative disease in the thoracic 23 spine? 24 A I don't know. 25 MR. WILT: Take a second and look, 0025 1 Doctor. 2 MS. KOLIS: You can have more than 3 a second. I know the records are voluminous, that 4 is why I'm not in a rush. 5 A Are you aware of anything in my notes? 6 Q I would love to answer questions. 7 A Sometimes I say no, then somebody points out 8 something in my notes I didn't see. 9 Q The truth of the matter is I'm not, but that 10 doesn't mean it's not there. 11 A I actually don't recall ever -- I had several 12 x-rays over the years of the L-1 area. 13 MR. WILT: There is a CT scan of 14 the thoracic spine on 10-8-90. 15 MS. KOLIS: About a decade before 16 this procedure. 17 MR. WILT: What's your question? 18 MS. KOLIS: I asked if at any point 19 he was aware of degenerative disease in the 20 thoracic spine area. 21 A I would assume that he would have degenerating 22 disks in the thoracic spine. A lot of the x-rays 23 that had been taken in the area around his L-1 24 would have shown the thoracic spine. All you 25 really see on the regular x-ray is sort of a flat 0026 1 disk. 2 Q You didn't have any independent or specific MR or 3 CT studies done of the thoracic spine up to the 4 point of July 7, 1999 is that -- 5 MR. WILT: Let me object. This is 6 a CT scan of the lower thoracic spine. 7 THE WITNESS: In 1990. 8 MR. WILT: If you are saying up to 9 that point. 10 Q You had one done in 1990 evaluating what parts of 11 the body? I don't know that I have that report. I 12 may have it. 13 A Lower thoracic spine post myelogram and CT of the 14 lumbar spine. They have a section for the mid body 15 at T-9 to mid body of T-12. It says there is a 16 large calcified spur seen laterally at T-10/11 on 17 the left. Posterior bulging of the disk at the 18 T-11 level to the left of midline obliterating 19 subarachnoid space. 20 Q Can I inquire the date of that study, because I am 21 fairly certain I do not have that one? 22 A October, 1990. October 8, 1990. 23 Q To the best of your knowledge, between October 8, 24 1990, up to July 7, 1999, did you ever have another 25 occasion to examine or evaluate findings in the 0027 1 thoracic spine on Mr. Lasko? 2 A No, not that I'm aware of. 3 Q We will let counsel look for a minute. I thought I 4 had the records from 1990 through present. 5 A That particular one was directed at looking at the 6 level of the fusion. It was incidental that you 7 saw the thoracic spine. 8 Q That was going to be my next question. In terms of 9 this examination of October 8, 1990, you did not 10 order that study to evaluate the thoracic spine. 11 The thoracic spine was an incidental finding 12 because you were hooking at what was below it, 13 correct? 14 A Yes, just below it. 15 Q On July 7th you evaluate Mr. Lasko, you discuss 16 with him again regarding his pain syndrome, a 17 dorsal column stimulator, correct? 18 A Yes. 19 Q Doctor, at what point did you advise Mr. Lasko as 20 to what the risks were for the placement of a 21 dorsal column stimulator? 22 A I probably told him about them several times over 23 the -- at the different times I talked to him about 24 the dorsal column stimulator. I don't remember 25 specifically which time I did, which times I 0028 1 didn't. I would have described the procedure to 2 him at those times too. 3 Q Would you agree with me there is nothing in the 4 narrative portion of your office notes indicating 5 that you advised Mr. Lasko of risks and what those 6 risks specifically were? 7 A I would agree with that. 8 Q Have you had an opportunity to review the informed 9 consent that you had Mr. Lasko sign prior to 10 surgery? 11 A No. 12 Q Let me mark that 3. 13 (Plaintiff's Exhibit 3 14 marked for identification.) 15 Q Doctor, I'll hand you what I believe to be the 16 informed consent signed by Mr. Lasko relative to 17 this surgery. Can you identify this document? 18 A It says consent to surgery or other procedures, 19 Fairview Health System. 20 Q Lutheran Hospital was Fairview Health Systems on 21 August 17, 1999? 22 A Yes. 23 Q That is the date when he signed it, correct? 24 A Yes. 25 Q Doctor, do you have an independent recollection of 0029 1 seeing Mr. Lasko on that date, explaining to him 2 the risks of the procedure? 3 A On August 17th? 4 Q Right. I didn't see a companion office note, I was 5 curious. 6 A I wouldn't have seen him then. 7 Q Who explains the risks to the patient that allows 8 the patient to sign this document? 9 MR. WILT: Objection. 10 A I explain the risks to him in the office. 11 Sometimes I tell them about things immediately 12 pre-op if I think I've forgotten to. The nurse 13 clinicians will a lot of times explain the risks to 14 them in pre-anesthesia, where this is normally 15 signed, or actually in preadmission testings. 16 Q PAT they go through these things. 17 Would you agree with me that on the 18 particular document that Mr. Lasko signed, there is 19 not an explanation of the specific risks of this 20 procedure; would you agree with that? 21 A This is a general document that is used for all 22 surgeries. Nobody signs one that outlines all the 23 specific risks of a procedure they are undergoing. 24 Q No one at Lutheran Hospital, or no one in the 25 universe? 0030 1 A No one at Lutheran Hospital. 2 Q Let me ask you then if I can have this document 3 back, although there is no notes that confirm the 4 same, what you would have told him the risks of the 5 placement of the dorsal column stimulator were? 6 A I combine that with a description of the procedure. 7 Q Why don't you go through that for me? 8 A I tell him what we're going to do. I tell them we 9 do it under local anesthetic. The reason we do it 10 under local anesthetic is to minimize the risks 11 because we're putting something in his spinal 12 canal, there is only a only certain amount of room 13 there. We also need to do it while he's awake in 14 order to get the electrode placed optimally. If 15 you stick it in there under general, you don't know 16 if it's the right place or not. 17 We do a screening procedure then. The 18 physical therapist is the one who actually programs 19 it. Sometimes somebody from Medtronic is there to 20 help them. 21 Q Medtronic being the provider of the product itself? 22 A Yes. 23 Q Go ahead. 24 A What they do is they check -- they try different 25 settings on the electrode to see if they can get 0031 1 optimal coverage of his pain. If they can't, I 2 would move the electrode appropriately to try to 3 get that coverage. 4 I close it up. He gets off the table, goes 5 home. Doesn't go home that day. 6 What we also do is bring the electrodes 7 out through the skin. I tell them that it may be 8 we'll have to remove the electrodes, that they may 9 not work. They may have problems from the presence 10 of the electrodes. There is a fairly high risk of 11 infection because of the electrodes coming out 12 through the skin, repeating the procedure two days 13 later, where you then cut the electrodes off, bury 14 them. 15 Q Out of curiosity, once again my ignorance is 16 showing, originally as written in your office note 17 of July 7th, it looked like you were planning a two 18 part surgery. Surgery, the laminectomy to insert 19 the dorsal column electrodes was to be on the 24th? 20 A Yes. 21 Q The implantation of the stimulator itself was to be 22 two days later? 23 A That's correct. 24 Q I wanted to make sure I read it correctly, that 25 wasn't a miswrite, you really planned it that way? 0032 1 A That is the way I put them in. 2 Q Back to where we were. You explained to the client 3 that there is a very high risk of infection? 4 A Higher than other operations because we are taking 5 electrodes that come out through the skin. We put 6 special dressings on there that are never violated 7 until the second surgery. 8 Then we spend two days screening them where 9 they are actually sitting up, walking, sometimes 10 that changes things. It changes because the 11 electrode changes in position during that period. 12 So we're trying to see if we're still able to get 13 the area blocked that we're interested in. To see 14 if the patients have any problems. 15 Sometimes the patients will get pain or 16 excessive stimulation or muscle spasm in areas that 17 are uncomfortable and we can't use the electrode. 18 Q Before you fix it in a permanent position, you want 19 to make sure the stimulator is giving the patient 20 optimum relief for the symptoms that you 21 contemplated the procedure, correct? 22 A The stimulator itself is very expensive, runs 23 between 6 and 8,000. Prior to implanting the 24 stimulator itself, we want to make sure it's going 25 to work the way we want it to. There is a two-day 0033 1 screening period. 2 Under general anesthesia, we have to tunnel 3 this electrode all the way around to their 4 abdomen. I prefer they do that under general 5 anesthesia. Two days later we put them to sleep, 6 cut the skin and open the incision, put in a new 7 connector, implant the actual device. 8 Q So you would have told the patient risk of 9 infection. Would you have given him a percentage, 10 X percent of persons who undergo this? 11 A No. 12 Q You tell him it is higher than the average 13 operation? 14 A Yes. 15 Q Did you discuss with him there was a potential that 16 there would be no therapeutic value gained by 17 attempting to place this in there? 18 A Yes. The way I describe that actually is I say 80 19 to 85 percent of people will get a good result from 20 it. The others we have to remove the electrode. 21 Q When you are quoting him 80 to 85 percent, are you 22 relying on your personal experience as a physician, 23 or are you referring to literature that discusses 24 success rates in dorsal column stimulator 25 placement? 0034 1 A If are you looking at the way I do it, with the 2 wide electrode that is sent through the 3 laminectomy, it's both, my personal experience and 4 apparently the literature. 5 Q Do you, Doctor, have an opinion, as to the 6 percentage of persons who experience hemiplegia, 7 paraplegia, or paresthesia from the insertion of 8 these stimulators; do you know? 9 A As to paraplegia, I don't know the percentage. 10 Everybody has paresthesia, the goal is to change 11 your pain into a paresthesia. 12 Q I asked it incorrectly I suppose then. 13 In other words, you can dispute me, that is 14 why we're here, if I told you that my expert will 15 testify to, and I've confirmed it through 16 independent literature, that the risk of a person 17 becoming paraplegic from the placement of a 18 stimulator is less than .05 percent, do you have a 19 reason to dispute that figure? 20 MR. WILT: Objection. 21 A No, I don't. 22 Q Do you have any idea why it is that some people 23 experience paraplegia after the placement of these 24 stimulators? 25 A I can think of some reasons why they could. 0035 1 Q Tell me why they could. 2 A An expanding hematoma, epidural abscess, or too 3 narrow a canal where there is pressure on the 4 spinal cord. 5 Q How about the displacement of a disk that was not 6 previously known to the physician during the 7 procedure? 8 A That would be narrowing of the spinal cord or 9 narrowing of the spinal canal. 10 Q Mr. Lasko, I'm sort of jumping ahead. I like to 11 clean up details when we're there. 12 He did not, from my review of the records, 13 have an expanding hematoma subsequent to this 14 procedure; would you agree with that? 15 A Didn't appear that he did. 16 Q He did not have an epidural abscess, would you 17 agree with that? 18 A Yes. 19 Q He did in fact however have a narrowing of the 20 spinal canal? 21 A He had what is called a hard disk, which is a bony 22 spur that was quite large -- he actually had two. 23 One larger than the other, at two of the levels we 24 put the electrodes in. 25 MR. WILT: Let me take a break now 0036 1 and talk to the doctor. 2 (Recess taken.) 3 By Ms. Kolis: 4 Q Dr. Bohl, prior to placing the dorsal column 5 stimulator, you had a plan as to what level you 6 were going to do your laminectomy for the insertion 7 of the electrodes, correct? 8 A Yes. 9 Q That level was where? 10 A T-9/10. 11 Q Why did you elect that level? 12 A That is the usual level. 13 Q Good answer. 14 A I mean where you get the best distribution. 15 Q You want to insert it there so you can get maximum 16 relief for the patient should this procedure end up 17 being effective, correct? I believe the operation 18 was going to be at T-10, T-11? 19 A I'll tell you I always have to think about that. I 20 usually end up pulling a previous patient's chart 21 to get the right one. T-10/11, you slip the 22 electrode up past T-9/10. 23 Q Would you agree with me the standard of care 24 required that you know what the spinal column 25 architecture and spinal cord itself looked like in 0037 1 that area prior to performing this procedure? 2 A No. 3 Q Why do you think that is not the standard of care? 4 A Because I'm not aware of anyone anywhere who 5 recommends that that be done as a routine. A 6 thoracic spine MRI be done as a routine before you 7 put in a dorsal column stimulator. 8 Q Let me ask the question a different way. 9 Subsequent to the procedure you in fact had an MRI 10 performed that scanned the thoracic spine; is that 11 a fair statement? 12 A I don't know. 13 Q We will mark this Plaintiff's 4, MR of the thoracic 14 spine dated 8-26. 15 (Plaintiff's Exhibit 4 16 marked for identification.) 17 MR. WILT: This is interesting 18 because I got these records from you, Donna, and I 19 was never provided this MR. 20 MS. KOLIS: Pages 40 and 41. 21 MR. WILT: I don't have that. All 22 the radiology studies that I have -- 23 MS. KOLIS: It's reported in his 24 summary of the case. I'm a little surprised you 25 wouldn't have it in his chart. I think it was in 0038 1 his chart. 2 MR. WILT: Not in the hospital 3 records you gave me. 4 MS. KOLIS: In his own office 5 chart. That is where I originally got it from. 6 MR. WILT: All right. 7 A This is misdated. I never -- this is the one I 8 ordered postop. 9 Q I would -- 10 A I never ordered one pre-op. 11 Q I understand that. This is postop, dated 8-26-99. 12 A Okay. 13 Q Are you with me? 14 A Yes. 15 Q Here is my question, I'm going to try to make it 16 simple: If you had known prior to the surgery that 17 there was multiple level -- I'm reading right out 18 of the report, at the bottom says multiple level 19 diskogenic disease is present at the lower thoracic 20 spine. This is most severe at T-9/10 where there 21 is a focal right paracentral disk protrusion 22 indenting into the ventral thecal sac. Disk height 23 loss is present, yadda, yadda, yadda, et cetera. 24 That is how far I'm going to read it. 25 If you had known this disk was there in 0039 1 this presentation, would you have done something 2 differently in approaching the installation of this 3 dorsal column stimulator and/or electrodes? 4 A If it had been large enough, I probably would have 5 not done the procedure. 6 Q Explain in layman's terms why you wouldn't do the 7 procedure, quote, unquote, if it, being the disk, 8 was large enough? 9 A It might not leave enough room in the spinal canal. 10 Q For? 11 A For the electrode. 12 Q Is there some other risk that you can perceive of 13 proceeding with the insertion of dorsal column 14 electrodes in anticipation of a stimulator in the 15 face of a disk at that location? 16 A What was the question, some other reason? 17 Q In addition to you saying there might not be enough 18 room for the electrodes, the mere act of attempting 19 to place them in, do you see it causing a problem 20 with the disk of size at that level? 21 MR. WILT: Objection. I still 22 don't understand. If you don't understand, she can 23 rephrase it. 24 A I think I know what you are getting at. 25 Q Is there some other complication that can be 0040 1 encountered other than there not being enough room 2 for the electrodes if you attempt to install these 3 electrodes at that level in the face of a disk 4 described on the MR report? 5 MR. WILT: Objection. 6 A If you are not careful about taking the lamina off, 7 you can damage the spinal cord. I'm always very 8 careful as if the canal is narrow. 9 Q I'll take that back, let's talk about your op 10 report for a minute. See if I can find your 11 operative report, have that marked 5. 12 Before we do that, Doctor, as part of 13 pre-operative testing, PAT some people call it, 14 there are a number of tests you have ordered; is 15 that correct? 16 A Yes. 17 Q To make sure the person is a suitable candidate for 18 surgery; is that probably a fair statement? 19 A A reasonable candidate, yes. 20 Q In Mr. Lasko's case you would have ordered a chest 21 film, correct? 22 A Yes. 23 Q I'll mark this 5. 24 (Plaintiff's Exhibit 5 25 marked for identification.) 0041 1 Q Doctor, I'm handing you what I believe to be the 2 x-ray report from 8-17; do you agree with me that 3 is apparently what this is? 4 A Yes. 5 Q In the conclusion the radiologist says segmental 6 scarring both bases, referring to the lungs of 7 course; would you agree with that? 8 A Yes. 9 Q And then his second finding is scoliosis and 10 degenerative changes involving the thoracic spine; 11 am I reading that correctly? 12 A Yes. 13 Q Would you have seen this before you performed the 14 procedure on Mr. Lasko? 15 A No. 16 Q Why wouldn't you as a physician involved in making 17 certain a patient is ready for surgery not have 18 seen this x-ray reading? 19 A I normally don't. It's the anesthesiologist who 20 checks it before he puts the patient to sleep. The 21 operating surgeon doesn't normally look at x-ray 22 reports. 23 Q Wouldn't a copy of this have gone to you since you 24 were the doctor requesting it? 25 A It probably would have gotten into my office 0042 1 eventually, but not before the surgery. 2 Q You have no recollection of seeing that document 3 before the surgery? 4 A I didn't see it before the surgery. 5 Q If you would have seen it, would you have been 6 curious as to the nature of the degenerative 7 changes in the thoracic spine knowing that was the 8 area of the body where you would be placing the 9 dorsal column stimulator? 10 A It wouldn't have changed anything. I assumed all 11 along he has degenerative changes in his thoracic 12 spine. 13 Q You assume he did, you didn't know the nature and 14 extent of those changes; is that a fair statement? 15 A Almost everybody in Mr. Lasko's condition has 16 degenerative changes in the thoracic spine. It's 17 very unusual to have a spur that size. 18 Q That wasn't my question. You assumed he had 19 disease but did not know the nature and extent of 20 it because there weren't any diagnostic tests 21 ordered by yourself to define that prior to the 22 surgery? 23 A That's correct. 24 (Plaintiff's Exhibit 6 25 marked for identification.) 0043 1 Q This I believe, Dr. Bohl, is your operative summary 2 from Mr. Lasko from August 24th. There were a 3 couple of questions that I wanted to ask you about 4 this. 5 You had mentioned earlier in your testimony 6 that upon occasion the technicians from Medtronic 7 are in attendance at the procedure, were they in 8 attendance at Mr. Lasko's procedure? 9 A I don't remember. 10 Q You don't have any recollection of that? 11 A No. 12 Q Where it says anesthesia standby, can I assume they 13 were standby because you were only giving him a 14 local, had them ready in case anything rent wrong? 15 A They usually give him a little sedation then. Not 16 so much he can't answer the questions, can't tell 17 us he's having pain somewhere. 18 Q You didn't use the word, I used the word in 19 twilight, so he doesn't feel all the pain, he can 20 cooperate so that you know whether what you are 21 doing is effective, is that -- 22 A I would say they are less than twilight. They are 23 really pretty able to tell you what is going on. 24 Q You remember being able to talk to Mr. Lasko? 25 A I don't have an independent recollection of the 0044 1 conversation, but I know that things went okay. 2 Q If he had been unable to cooperate with you by 3 answering your questions or anything else during 4 surgery, you would have noted it some place; is 5 that right? 6 A We would have woken him up enough so he was 7 cooperative. 8 Q Fair enough. I was just asking. 9 Describe for me, if you will, exactly how 10 you did this procedure, you can read from your note 11 if you want to, then I can ask you some questions 12 about it. 13 A Normally I put in some local anesthetic. Then you 14 make an incision from the spinous process of T-10 15 to T-11. Use what is called a Cobb elevator to 16 strip the soft tissue off that level. Then I 17 normally take a rongeur to open up the space 18 between the two levels so you can get down to the 19 lamina. 20 Then what I normally do is take something 21 called a ganglion knife, which isn't really a 22 knife, very thin elevator, I try and work my way 23 down to the back of the lamina, so that I can get 24 the ganglion knife just under the back of the 25 lamina. So as not to compress anything, but so 0045 1 that I can get what is called a Kerrison punch, 2 very small instrument, just under the lamina and 3 start trimming it away. 4 Usually I trim enough lamina away so I 5 don't have to disturb the ligamentum flavum. Once 6 I have the lamina opened up, enough of a 7 laminectomy wide enough that I can put the spatula 8 in, we slip the spatula in. They are used to make 9 sure there aren't adhesions and make sure there is 10 enough room in the spinal canal to accommodate the 11 electrode. Normally the spatula slips right in. 12 Q When you are saying the spatula, in this version is 13 this the paddle or not? I wanted to be sure what 14 I'm looking at. I was with you so far, you got me 15 through the ligamentum flavum, then you are saying 16 a Medtronic syntax lead paddle, that is the same as 17 spatula? 18 A Yes, rigid plastic thing with a curve on it. 19 Q Approximately what size is the Medtronic lead 20 paddle? 21 A Approximately the size of the electrode, only you 22 can put it in further up, it's longer. 23 Q A Medtronic syntax lead paddle was inserted beneath 24 the lamina of T-10, pushing it upward, noting what 25 felt to be a block part way in. 0046 1 What do you believe that block was at the 2 time as you are in surgery? 3 A Well, it can be adhesions. It can be a narrow 4 area. 5 Q Narrow area caused by a disk? 6 A Could be. 7 Q Did you give any thought as to why it was you were 8 feeling a blockage? 9 A Well, I know it could be one of those things. It 10 was up fairly high. I didn't have any trouble 11 slipping the electrodes in. It was up above, kind 12 of at the upper end of where the paddle slipped. 13 So that I probably would not have been able to move 14 his electrodes up like you need to do in some 15 patients. I didn't have any trouble slipping them 16 into the space that was there. 17 Q So you felt this blockage. What did you do once 18 you encountered the blockage? 19 A I took the paddle out, slipped the electrode in, 20 called a syntax lead. 21 Q Today, based upon your evaluation of the records 22 and all the diagnostic tests that were done 23 subsequent to this procedure, do you know what that 24 blockage was you encountered at the time of 25 surgery? 0047 1 A I'm not sure. Could have been a spur on the T-8/9 2 disk. 3 Q Could it have been anything else? 4 A Adhesions. 5 Q Do you find any adhesions at that level when you 6 went in to do the laminectomy, diskectomy later in 7 August? 8 A You can't see that. 9 Q So you wouldn't see that. 10 According to your operative -- when I say 11 your operative report, I'm talking about this 12 typewritten report that was referred to as document 13 number 6, you indicate that following the procedure 14 the patient was transferred to the recovery room in 15 satisfactory condition. 16 Have you examined the medical records 17 sufficiently enough to show me where in the medical 18 record it shows that following the procedure 19 Mr. Lasko had motor and sensory function from T-10 20 and below? 21 MR. WILT: Other than what he is 22 stating in his operative report? 23 A I didn't follow him to the recovery room. He 24 assisted us. I put the patients on the cart 25 myself. Mr. Lasko climbed on the cart, got on the 0048 1 cart. Did not mention anything about numbness or 2 any -- certainly didn't have any weakness when he 3 was climbing on the cart, or all the while he was 4 being screened for 10 to 15 minutes. 5 Q When you say screen, you are talking still on the 6 table, you've got the electrodes inserted, you 7 are -- I don't know what word you want me to use, 8 measuring activity or monitoring the activity, is 9 that the screening portion you are discussing? 10 A What happens is the physical therapist, Medtronic 11 rep -- actually if the Medtronic rep is there the 12 physical therapist is usually there too anyway. 13 Yes, they check the different settings, try and 14 find the optimal distribution of pain. As the 15 patient is blocked, when they say yes, we think we 16 have the optimal spot, we close up, which takes 17 another probably 15 minutes, so you are talking 18 total time the electrodes are in approximately 25 19 minutes before the patient climbs himself back onto 20 the table. 21 Q Are you saying you have an independent recollection 22 following the procedure you were still in the room 23 and you saw him get onto this cart by himself? 24 A I certainly did. 25 Q So my question was, I don't see that documented any 0049 1 place other than your written summary. I was 2 curious, did you place any note in the chart, a 3 hand written note regarding that fact? 4 A Patients all do that. I don't put it in the op 5 note or anything. 6 Q When were you first aware that he had lost motor 7 and sensory function following the procedure? 8 A I think I was in another case, the one that 9 followed that one. Somebody from the recovery room 10 called me, told me that. 11 Q Is it your understanding, based on your review of 12 the records and/or your recollection, that this was 13 his situation when he actually arrived in the 14 recovery room? 15 A I don't know. I don't recall whether it was in the 16 recovery room or very shortly after. 17 Q All you are indicating to me by your answer is 18 you've not reviewed these records prior to today 19 carefully enough to know with precision at what 20 time the first report was that there was a loss of 21 motor and sensory function? 22 A I guess that is right. 23 Q From your best recollection of your own personal 24 notes, how long after you finished Mr. Lasko's case 25 do you believe that became evident to the support 0050 1 staff in the hospital? 2 MR. WILT: Objection. 3 Q You can answer it. 4 A I remember seeing some note from the recovery room 5 that looked like it was early on. Indicates that 6 it was about the time he got over or shortly after. 7 Q To the recovery room? 8 A Yes. 9 Q Doctor, when they reported to you this set of 10 symptoms, what was your belief as to what 11 Mr. Lasko's problem was? 12 A We thought it was the epidural effect of some local 13 anesthetic I just put in his wound. 14 Q In how many patients prior to Mr. Lasko had you 15 ever seen them lose motor and sensory function due 16 to epidural medication? 17 A There haven't been more than one or two patients I 18 put the additional medication in. The answer is 19 none I remember. 20 Q Sometimes I don't ask good questions. I try to. 21 Did you have anything else in what we 22 lawyers love to use the phrase differential 23 diagnosis what the cause of the problem could have 24 been at that point? 25 A Yes. 0051 1 Q What was it? 2 A In my mind the differential diagnosis initially, 3 was effect of the epidural, effect of the 4 anesthesia, or possible constriction. 5 Q Constriction due to? 6 A To not being enough space in the canal. 7 Q For? 8 A For the electrode. 9 Q Those were the two things you were thinking about? 10 A Yes, initially. 11 Q You can correct me any place I'm wrong. I really 12 prefer to do depositions this way, the stream of 13 consciousness. 14 It's my understanding based upon a review 15 both of the progress notes and then a document that 16 you typed, I think a discharge summary, there was 17 approximately a three hour period of time between 18 onset of symptoms and decision to undergo an 19 emergency removal of the epidural electrodes; am I 20 stating that accurately? 21 A Yes. 22 Q Was there a reason why you wanted to wait for three 23 hours? 24 A Yes. 25 Q What was the reason? 0052 1 A We wanted to see if it was the epidural effect. 2 What we did, we initially decided to wait an hour, 3 see what would happen. In that hour he got all of 4 his sensation back, a lot of the motor use of his 5 left leg. So, we figured, well, it's probably the 6 epidural effect. We will wait longer, see what 7 happens. We did wait longer, when it stopped 8 getting better, that is when we made the decision, 9 three hours postop. We still didn't know for sure 10 it wasn't the epidural effect, but we decided we 11 didn't want to take the risk. 12 Q So you decided to go ahead and do an emergency 13 removal of the electrodes? 14 A Took them out. 15 Q Was there any improvement in the patient's symptoms 16 that he presented with following the insertion of 17 the electrodes? 18 A There was some. 19 Q What to the best, you can refer to your notes, to 20 the best of your recollection was the improvement 21 that you experienced by removing the electrodes? 22 This isn't a hidden ball trick. Let me mark this 23 for you. Do it either way. 24 A My note following removal of the electrode, 25 sensation returned, motor still gone, voiding. It 0053 1 was primarily sensory return. 2 Q He had a sensory turn. Did he not, Doctor, I'm 3 just sort of making it faster for us, as I read 4 your note, discharge note, after you removed the 5 electrodes did he regain more motor function in the 6 left leg, none in the right; would you agree with 7 that? 8 A Yes, he did. 9 Q I think subsequent to removal of the electrodes a 10 portion of this motor use, particularly in the left 11 leg, rapidly returned, some minimal return on the 12 right side? 13 A Yes. I should make a correction. If I look at my 14 notes, apparently before we removed the electrodes 15 sensation had come back, motor had not. 16 Q Fair enough. I think the notes were 17 self-explanatory. 18 In your discharge summary you indicate, I 19 think we already looked at it, I want to go over 20 this again, MRI was done which showed a large hard 21 disk at T-10/11 interspace occluding approximately 22 half the canal. 23 A T-9/10. 24 (Plaintiff's Exhibit 7 25 marked for identification.) 0054 1 A I'm looking at the note in the chart. 2 Q We will go through both of them to make sure which 3 is correct. 4 Can you identify that is the discharge 5 summary which you prepared for Mr. Lasko? 6 A Appears to be. 7 Q It shows dictated on September 20, 1999, 8 transcribed October 14th, at the bottom your name, 9 correct? 10 A Yes. 11 Q You don't have residents who dictate these for you? 12 A No. 13 Q In that one, you're indicating on what you dictated 14 at that time, an MRI was done which showed a large 15 hard disk at T-10/11 interspace, occluding 16 approximately half the canal? 17 A Yes, T-10/11 is incorrect, it would be T-9/10. 18 Where I say I re-explored it is T-9/10. It 19 wouldn't make sense. 20 Q I was just asking. I thought I would try to find 21 out what you believed the situation was. 22 Doctor, based upon what you saw at MRI, two 23 days subsequent to this procedure, is it your 24 opinion that his loss of motor function and 25 sensation was caused by that large disk at the 0055 1 T-9/10 space? 2 A Well, initially that is what I thought it was. I 3 thought it was the pressure of the electrode, and 4 the disk compressing the spinal cord. 5 Q Fair enough to say prior to him getting up on your 6 table on August 24, 1999 he had motor and sensation 7 function T-10 and lower, correct? 8 A He had some left-sided weakness, but that was 9 residual from the previous surgery. 10 Q That immediately following the surgery -- when I 11 say immediately, let's call it within 45 minutes, 12 do you think that is fair from the time you 13 finished the procedure until it was appreciated he 14 lost motor and sensory function, correct? 15 A Yes. 16 Q So I'm asking you as we sit here, is it clear to 17 you that by pushing those electrodes or using the 18 paddle the way that you did, the disk was pushed 19 into the canal, therefore become occluded, that is 20 why this situation occurred? 21 A Actually I think that the posture had something to 22 do with it. It was an occlusion of the electrode 23 and the disk. 24 Q I'm sorry, because I have a bad habit of listening 25 and moving papers, you think it was posture? 0056 1 A When we do the surgery the patient's back is flexed 2 like this. We put the electrode in, there is 3 plenty of space, he lays there for another 20 4 minutes or so. No problem. 5 When we get him off the frame, his back 6 goes like this, his back extends, which shortens 7 the spinal canal. If the electrode happens to be 8 near the disk, it's possible by that change in 9 posture for it to actually be pushed into it. That 10 could explain why nothing happened until he got 11 over to the -- 12 Q It would be the postural change as it relates to 13 the electrodes being near the disk the causes this 14 problem? 15 A That would be the explanation for why he didn't 16 have problems on the table, but did when he got to 17 the recovery room. 18 Q Suffice it to say if the disk was not at that 19 location, that usually wouldn't be a complication; 20 would you agree with that? 21 A That is probably correct. 22 Q In retrospect, wouldn't it have been preferable to 23 have done a diskectomy at the level prior to this 24 procedure being performed? 25 A You would have to know there was a disk there 0057 1 first. 2 Q Of course you would. If you had known there was a 3 disk there, can you medically agree under those 4 circumstances the disk we have described in the 5 studies, a diskectomy being performed prior to the 6 insertion would have been the medically appropriate 7 way to go in this situation? 8 A You probably would not have done the insertion. 9 You probably would not have done a diskectomy to do 10 the insertion. Especially in this patient. Much 11 too high risk. 12 Q To do the diskectomy? 13 A Yes. 14 Q Therefore you could have given the client the 15 medical option not to undergo the dorsal column 16 stimulator because of the disk? 17 A That's correct. 18 Q Fair enough. That is what I wanted to know. The 19 next documents are 8A and 8B. 20 (Plaintiff's Exhibits 8A & B 21 marked for identification.) 22 Q I would like for you, Doctor -- I believe this is 23 your progress note dated 8-26, starts on this page 24 and continues; am I identifying that document 25 correctly? 0058 1 A Yes. 2 Q What we're going to do is read this progress note 3 of 8-26-99 into the record. So if you begin I'll 4 try not to interrupt you. Go back and ask you 5 questions afterwards. 6 A Sensation still good, has early pressure area left 7 heel. Have instituted decubitus precautions. 8 Yesterday had only flexion/extension of the left 9 foot. Today better active motion left foot. Some 10 recovery of other muscles. Right side now has 11 flicker of plantar flexion. No BM yet. 12 Spontaneously voids. Appears to be gradually 13 recovering. Reviewed MRI, which shows large hard 14 disk at T-9/10 protruding approximately halfway 15 across canal. Apparently flexible electrode strip 16 put in at T-10/11 slipped upward, causing 17 additional compromise of cord blood supply at upper 18 tip, resulting in anterior cord syndrome. 19 Compromise lasted about three and a half hours, 20 probably partial because deficit was not present on 21 OR table. Developed after went to recovery. Have 22 informed patient of probable scenario and 23 likelihood of at least partial recovery, although 24 no way to know if it would be complete. Reviewed 25 neurology note, laminectomy not indicated since 0059 1 source of acute compression has been removed. 2 Patient is improving, problem is anterior, not 3 posterior. At this time further trauma to cord 4 would compromise recovery. Will observe now for 5 improvement. If significant deficit persists, will 6 consider thoracotomy for removal of disk at T-9/10 7 and anterior decompression, once initial cord 8 swelling diminishes, making increased injury less 9 likely. Will taper steroids, start physical 10 therapy, bowel management, start prophylaxis, my 11 associates will follow until Monday 12 Q Were you going out of town over the weekend? 13 A Apparently. 14 Q You stand by that note as you wrote it? 15 A Yes. 16 Q It is my understanding that you then did carefully 17 watch the patient for an additional week or so in 18 looking for some additional functional recovery, 19 because that did not occur, you did make a decision 20 to perform an additional surgery; am I stating that 21 fairly? 22 A There was a precipitating event for deciding to 23 perform the additional surgery. 24 Q Tell me about that precipitating event. 25 A There was an occasion when I was called and told 0060 1 that Mr. Lasko had been put in a chair, sitting 2 upright, that when they came in, I don't know, I 3 don't know the exact circumstances, but the way it 4 boiled down he was sitting in this chair for a 5 period of time, it was noted that when they went to 6 move him he had no sensation or motor function at 7 all. The same as the time when he had come off the 8 table. 9 Q Not to be trite about it, sort of a reversal of 10 fortunes, he was making progress, then this episode 11 occurred? 12 A Yes, complete reversal. 13 Q So you made a decision in spite of what you 14 perceived to be some risk perhaps in doing a 15 diskectomy, you thought that would be his best 16 opportunity for some recovery, correct? 17 A Well, the initial thought was to wait and see how 18 much recovery he had and possibly hopefully not do 19 anything further surgery-wise. 20 This event made us realize we were not 21 going to be able to do that. We took an additional 22 period of time in which we did not allow him to the 23 sit up or get up. To allow things to still 24 improve. Then we took him to the operating room, 25 did the surgery. 0061 1 Q The first surgical procedure that you did in 2 response to the situation occurred on -- do you 3 happen to recall the date of the surgery, Doctor? 4 I might have it. 5 MR. WILT: 9-9. 6 Q He was always in the hospital, in different 7 departments. This was his return to this surgery. 8 Do you know if that surgery was done 9-9? 9 MR. WILT: Yes, 9-9. 10 Q That sounds familiar. 11 A It was 9-9. 12 Q The surgery which you were to perform on 9-9 was a 13 T-9, T-10 diskectomy, posterior decompression, 14 right? 15 A Yes. 16 Q That is what you were planning? 17 A That was the plan. 18 Q Doctor, as we both know, you ended up doing surgery 19 T-8, T-9 inadvertently is the way you phrased it on 20 the 9th; is that correct? 21 A Yes. 22 Q Tell me how that happened? 23 A We put the patient in the lateral position. I 24 asked Dr. Rastgoufard, a thoracic surgeon, since 25 this is a particularly difficult level to get to, I 0062 1 asked him to do the exposure. He did the 2 thoracotomy. 3 We had, I remember we had difficulty with 4 x-ray, we took five sets of x-rays because they had 5 a new x-ray tech, we were having difficulty with 6 visualization. There was a lot of altered anatomy. 7 Both of us decided on the level that we 8 felt was the appropriate level. Then 9 Dr. Rastgoufard -- it's just a little opening, kind 10 of take turns looking in, he went and did an 11 incision through the pleura, removed the base of 12 the rib, exposed the level that I presumed that we 13 decided on. I don't know whether he got the right 14 level or not, it was the one I thought we decided 15 on. Did the surgery. 16 There was a disk at that level. The level 17 above also had a disk on the MRI too. I wasn't 18 surprised. In fact, it was a fairly sizeable 19 disk. Did the decompression. Closed up the 20 patient, sent him to the recovery room. 21 Q The operation that you intended to do, once again, 22 was T-9, T-10, correct? 23 A Yes. 24 Q You wanted to do T-9, T-10 because you believed 25 that was the source of the problem? 0063 1 A I believe that was the primary source. 2 Q You can correct me any time. 3 I guess I'm going to have to ask this 4 question simply. Do you take responsibility for 5 the fact that a procedure occurred at the wrong 6 disk level on September 9th? 7 A Well, I realized it occurred at the wrong level. I 8 feel that at the time of surgery we did all the 9 normal things to insure that we were at the right 10 level. I don't know what Dr. Rastgoufard did when 11 he got in there. Whether he inadvertently incised 12 over the wrong rib or not. The level he exposed is 13 the one I did. It appeared to be the proper level 14 at the time I did it because there was a big spur. 15 I obviously took responsibility for it. I 16 explained the problem to Mr. Lasko, did the right 17 level. 18 Q That was truly my question. Ultimately, Doctor, 19 since you were the surgeon, is it your 20 responsibility to insure that you were operating at 21 the right level? 22 MR. WILT: Objection. 23 A It's my responsibility to take the normal 24 precautions to try and insure I'm operating at the 25 right left, yes. 0064 1 Q What made you suspect, or did anything make you 2 suspect subsequent to that surgery on September 3 9th, that you operated on an unintended disk level? 4 A The thing that made me realize it was probably the 5 wrong level was that I got -- he made a partial 6 recovery from the level I did. Then was just 7 partial recovery. 8 I subsequently got x-rays to check the 9 location of the graft and everything. When I went 10 and reviewed them with the radiologist, actually 11 the radiologist had mislabeled the levels too 12 because of his altered anatomy, I was able to 13 determine from the rib base we resected it was 14 probably the wrong level. 15 Q A couple of questions along what you have said. 16 When you said he had a partial recovery, as 17 I read your discharge -- I believe your discharge 18 summary, the only recovery he had following the 19 surgery of September 9th was motor use of his right 20 foot; is that right? 21 A Yes, which had been very resistant to recovery 22 before. 23 Q That wasn't recovery you were expecting from doing 24 that diskectomy, correct? 25 A I was hoping to get some recovery. I didn't know 0065 1 if I would get any. There is no way of telling how 2 much damage was done. 3 Q Do you read plain film x-rays? 4 A Yes. 5 Q Do you make surgical decisions upon your 6 interpretation of them? 7 A Yes. 8 Q Did you mention anywhere in your discharge report, 9 or in a summarization note that you believed that a 10 radiologist had mislabeled the disk levels? 11 A No. Actually what I was referring to is when I was 12 reviewing them with the radiologist, she had 13 mislabeled them. I pointed out to her the correct 14 levels. There was no problem as a result of that. 15 Q That is what I -- unfortunately sometimes I hear 16 things, I say am I going to hear that at trial. 17 You are not saying the radiologist in 18 mislabeling something was a cause or contributing 19 cause to the fact the wrong disk level was operated 20 on? 21 A No. I was pointing out it was difficult to tell 22 where you were from the x-rays, even if you are a 23 radiologist in the radiology department. 24 Q Have you ever operated on the wrong disk level in 25 any other patient? 0066 1 A Once. 2 Q Did that result in a lawsuit, out of curiosity? 3 A No. 4 Q Subsequent to the correct procedure being 5 performed, Mr. Lasko did have some additional 6 improvement in his right leg; is that a fair 7 statement, after you got to the right disk? 8 A He had some improvement with the first disk and 9 second disk. 10 Q The first disk we discussed was a partial recovery 11 of the motor use of the right foot. What I'm 12 trying to make clear for the record is following 13 the diskectomy at the correct level, T-9, T-10, he 14 had more improvement? 15 A Yes, eventually he had a lot of improvement. 16 Q Eventually down the road -- we get to come back 17 full circle. When he came to see you after I filed 18 the lawsuit, did you do a physical examination? 19 A Yes, I did. 20 Q Counsel has graciously provided me with that note 21 some time in the past, it never made it into my 22 notebook. Can you tell us the date of that note 23 and read it into the record? 24 A April 11, 2001. 25 Q What does the note say? 0067 1 A It says doing better, uses wheel walker for 2 balance. Strength back to normal. Numbness gone, 3 no significant back pain. Complains of pain in 4 both knees only. That is what he told me. 5 Then the back when I actually examined him, 6 there was no specific tenderness in his back. He 7 was able to bend forward to 45 degrees, unable to 8 completely straighten. He had slight motor 9 weakness in the left foot flexors only, which is 10 what he had before surgery. It was better than 11 what he had before surgery. 12 Sensory exam was normal. I examined his 13 right knee. He had a small effusion in, tenderness 14 under the patellar facets. Range of motion 10 to 15 125 degrees. Tender joint line medially. Negative 16 McMurray sign. Left knee no effusion, tender 17 facets, range of motion 5 to 135 degrees. Unable 18 to get x-ray without referral. Discussed 19 happenings in the hospital. Would follow-up in 20 three months. 21 Q Out of curiosity, what does it mean when you say 22 discussed happenings in hospital? 23 A Actually I brought up the lawsuit with him. I 24 thought I told him it was sort of unusual that 25 somebody would come back to me after suing me. He 0068 1 said he wasn't sure he had yet. It was just being 2 looked into. I informed him in fact he had. I 3 asked him if there were some things he didn't 4 understand that I told him in the hospital, because 5 I thought we had gone over everything fairly 6 thoroughly. I reviewed that with him. 7 Q Based upon, once again I'm trying to listen and 8 look, you indicate based upon your physical 9 examination that his motor strength had returned. 10 Doctor, are you testifying under oath 11 Mr. Lasko has today all of the same motor strength 12 he had in both of his lower extremities prior to 13 the events of August and September of 1999? 14 A Well, he's got a little more strength in his foot. 15 He had dorsiflexion weakness in the foot before. I 16 couldn't say for sure he did. He may have some hip 17 weakness, it's a little hard to tell because he's a 18 little unsteady. 19 Q To the best of your recollection, or based upon 20 your documents, in terms of Mr. Lasko -- 21 A Let me add one thing. 22 Q Sure. 23 A He said his strength was back to normal. 24 Q You didn't do a physical examination to test for 25 all of that, did you? 0069 1 A Not all of it. 2 Q The reason I'm asking is, prior to the surgery, are 3 you aware of what Mr. Lasko's abilities were to 4 live independently? 5 A No, not specifically. 6 Q Do you know if he had to walk with assistance of 7 any sort? 8 A I think I recall times when he came in with a cane, 9 but I'm not sure. 10 Q That wasn't a cane you prescribed for him, was it? 11 A I don't remember. 12 Q Would it surprise you -- your attorney is going to 13 object to that -- we haven't seen all the records 14 yet, would it surprise you based upon Mr. Lasko's 15 physical status when he left the hospital, it took 16 a year plus in a nursing home to get him to the 17 point he could transfer in and out of a bed, walk 18 not incredibly long distances but walk with a four 19 wheel walker? I think what I'm getting at is in 20 your own initial note you didn't know what his 21 outcome would be given his cord had been compressed 22 for about three and a half hours initially? 23 MR. WILT: Objection. 24 A Correct. 25 Q You have not seen any medical records or notes with 0070 1 regard to his course of recovery at the nursing 2 home? 3 A I haven't seen nursing home notes, no. I did see 4 some of the notes down at the Cleveland 5 Metropolitan General Hospital when I visited him 6 there. 7 Q How many times did you visit him at Metro? 8 A Two or three times. 9 Q Who was in charge of his rehab at Metro, do you 10 recall? 11 A No, I don't recall. 12 MS. KOLIS: Doctor, I don't have 13 any further questions for you. Your attorney 14 obviously is going to tell you, you have the right 15 to read your deposition, and you are going to 16 because I won't let you waive. 17 THE WITNESS: I don't anyway. 18 (Deposition concluded at 3:44 p.m.) 19 (Signature not waived.) 20 - - - 21 22 23 24 25 0071 1 I have read the foregoing transcript from page 1 2 through 70 and note the following corrections: 3 PAGE LINE REQUESTED CHANGE 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 ____________________ 20 William Bohl, M.D. 21 Subscribed and sworn to before me this _______ day 22 of _____________________, 2002. 23 ____________________ 24 Notary Public 25 My commission expires: ___________________________. 0072 1 State of Ohio, ) ) SS: CERTIFICATE 2 County of Cuyahoga. ) 3 I, Constance Versagi, Court Reporter and Notary 4 Public in and for the State of Ohio, duly commissioned and 5 qualified, do hereby certify that the within named 6 witness, William Bohl, M.D., was by me first duly sworn to 7 testify the truth, the whole truth, and nothing but the 8 truth in the cause aforesaid; that the testimony then 9 given by him was by me reduced to stenotypy/computer in 10 the presence of said witness, afterward transcribed, and 11 that the foregoing is a true and correct transcript of the 12 testimony so given by him as aforesaid. 13 I do further certify that this deposition was 14 taken at the time and place in the foregoing caption 15 specified, and was completed without adjournment. 16 I do further certify that I am not a relative, 17 counsel, or attorney of either party, or otherwise 18 interested in the event of this action. 19 IN WITNESS WHEREOF, I have hereunto set my hand 20 and affixed my seal of office at Cleveland, Ohio, on 21 this 4th day of February, 2002. 22 23 ___________________________________________ 24 Constance Versagi, Court Reporter and Notary Public in and for the State of Ohio. 25 My Commission expires January 4, 2003.
