Chronology of injuries, surgery conducted and symptoms
4The plaintiff was born in December 1963. He was 42 at the time of the fall and 50 at the time of trial. He left school after Year 9 and went to work in various labouring and unskilled jobs. In about 1988, when he was about 24, he was employed by a stonemason as a marble fixer's assistant. While he was working at Botany Cemetery he injured his back, as a result of which he was off work for an extended period and was paid workers compensation.
5He underwent a laminectomy at L4/5 in July 1989 as a result of the injury in 1988. He returned to work afterwards. In October 1991 he suffered a further back injury when a vehicle in which he was travelling hit a dip in the road. A CT of the lumbar spine showed recurrence of the L4/5 disc prolapse with a large disc prolapse at L5/S1 which encroached on his nerve roots. In December 1991 he had further surgery to remove degenerative disc material and relieve compression of nerves at L4/5.
6After this time, he had various jobs, including as a security officer and a truck driver. The periods of employment were sporadic although he worked for the Department of Conservation and Land Management for about two years continuously. By 1992 it had become apparent that Mr Borg would never be able to work again as a labourer or in a position that required him to perform heavy duties.
7Mr Borg married in 1992. His first child, Sarah, was born in 1994 and his son, James, was born in 1998.
8By about 1993 Mr Borg reported that he was depressed as a result of his back condition and its effect on his ability to earn. He gave a history to Dr Metcalf in May 1993 of crankiness, irritability, restless sleep, subjective depression and suicidal ideation.
9In November 1995 Mr Borg was assaulted while working as a security guard. He was struck on the back of the head, knocked to the ground and kicked. He suffered concussion and injured his back. An MRI scan taken in April 1996 showed a posterior protrusion of the L4/5 disc.
10In March 1998 Mr Borg underwent a two-level spinal fusion. Cages were inserted at L4/5 and L5/S1. However he was dissatisfied with the results of the surgery. In November 1998 the cages were removed and a complete laminectomy over the two lowermost discs was performed. According to Mr Borg he was unable to work for about a year.
11Later, in about 1999, he started doing some security work. He worked as a security guard with Image Security at Hill Street Tavern for three shifts a week of between 7-8 hours each.
12Mr Borg's back was still giving him trouble. He consulted a further surgeon who advised him to have another operation, which was to be performed in February 2005. However, on 8 December 2004 he was involved in an altercation in the course of his employment as a security guard as a result of which he injured his right shoulder. An ultrasound scan revealed a full thickness tear involving the mid and posterior aspect of the supraspinatus tendon with tendon retraction of about 1.7 cms. The back operation was deferred.
13In February 2005 Mr Borg had surgery to his right shoulder that included arthroscopic acrominoplasty, rotator cuff repair and an evaluation of the glenohumeral joint. After the surgery he was admitted to the psychiatric unit at Sutherland Hospital for about five days due to the side effects of the medication.
14In about March 2005 he fell in the bathroom at home and tore his right rotator cuff again.
15In May 2005 he had further surgery to the right shoulder to revise the rotator cuff repair. According to Mr Borg neither of these operations was particularly successful.
16A fifth back operation was ultimately performed in December 2005, at which time a solid fixation was performed from L4 to the sacrum.
17According to Mr Borg, this back operation was very successful and assisted him greatly. He gave evidence that he was no longer required to take pain-killing medication for his back although he had, prior to the operation, taken Endone, Oxycontin and liquid morphine. He said that following the operation he required only Panadeine Forte for his shoulder. For reasons given below I do not accept Mr Borg's evidence unless it is corroborated or amounts to a statement against interest. I am satisfied that although his back was improved after the operation it continued to cause him difficulty.
18In any event, he was at that time disabled for work because of his right shoulder. An MRI scan taken in June 2006 demonstrated a complete re-tear of the supraspinous and infraspinatus muscle as well as atrophy. Professor Sonnabend, to whom Mr Borg was referred by Dr Kirsh, described his presentation at the end of August 2006 in the following terms, which I accept:
He is a big strong man with a major disability as a result of extensive disruption of his re-repaired right rotator cuff. His strength of forward flexion is scarcely anti-gravity, and his has virtually no active external rotation. This weakness interferes with various activities of daily living, and precludes him from working as a bouncer or a security guard.
19Because the earlier operations on his right shoulder had not achieved the desired result, Mr Borg was to have an arthroscopy on his shoulder on 8 November 2006 with a view to ascertaining whether it could be repaired. Following the arthroscopy, but before any repair was conducted, he fell from the operating table. This fall is the subject of these proceedings. At the time of the fall Mr Borg had not done any paid work for two years.
20Mr Borg was under sedation from the anaesthetic at the time of the fall. The operation record prepared by Professor Sonnabend noted:
"Traction removed; changed position from lateral decubitus to "beach chair". Surgical team left theatre to reswab; patient was being prepped when (according to wardsman who was holding arm) patient slipped- first right leg, then body, then head) off right side of table. Sister and wardsman were unable to support him (~ 135 kg) and patient fell to floor. Endotracheal tube pulled out; head hit floor from a [illegible] height of approx 1 foot."
21This record was admitted without objection. In my view, it fulfils the requirements of s 69 of the Evidence Act 1995 (NSW) since it is reasonable to infer that it was prepared by Professor Sonnabend on the basis of information supplied to him from the wardsman and sister, who were both present and involved and who might therefore "reasonably be supposed to have had personal knowledge of the asserted fact". Dr Donnelly's note does not add to the detail of what happened since he was facing in the opposite direction when Mr Borg fell.
22When Mr Borg regained consciousness, he complained of a headache in the right side of his head. Some right-sided weakness was noted in his arm and his leg. He was referred for a CT scan of his head and neck and spine. A MRI of his head and neck was unremarkable. Professor Sonnabend reviewed him the following day, 9 November 2006, and found him to be neurologically grossly intact with some low back and right hip discomfort. The nursing note in ICU made at 5.30 am on 9 November 2006 recorded in part:
"Pt very difficult to assess as weakness on R side varies and pt noted to be moving all 4 limbs spontaneously equally when not being assessed. Appears to have weakness and pain on movement when being assessed. Pt's pain level also difficult to assess, c/o headache earlier which he described as 10/10, 10 being worst pain, but then he fell asleep before pain relief given."
23On 15 November 2006, Mr Borg consulted Dr Rosenberg, his treating orthopaedic surgeon for his back. He complained that he had suffered a significant injury to his neck, head and back in the fall and that he was hemiparetic when he regained consciousness. Dr Rosenberg recorded that he had been extensively investigated with angiograms, MRI scans and CT scans which were relevantly clear. No cause for the right hemiparesis was found. At that time the principal complaint was a sore back with significant right-sided pain over the sacro-iliac region with shooting pain into his right leg. There was some soft tissue swelling in the right scalp.
24When Mr Borg saw Professor Sonnabend on 24 November 2006 he reported that he was still sore following the fall. Professor Sonnabend noted that his neck was still uncomfortable when he turned to the right and that the low back pain was slowly resolving.
25Mr Borg saw Dr Kirsh on 25 January 2007 with a view to rescheduling the operation that was to have been performed in November 2006. Dr Kirsh opined that his shoulder had slowly settled down and was neurologically "fine" although his back was stirred up and that he had had a "shake-up" psychologically. He noted that he still had diminished supination (which he had had before) and felt occasional pain in the palm of his hand.
26When Dr Kirsh reviewed him again on 6 March 2007, Mr Borg reported that the right shoulder continued to bother him and that he was comfortable proceeding with reconstruction of the rotator cuff. He also complained of bad right buttock pain.
27Dr Rosenberg reviewed Mr Borg on 9 March 2007. At that time the doctor recorded that he did not seem a great deal better, the spasms had returned and he had increased discomfort and pain from the right lower spine radiating to the right leg.
28Mr Borg's evidence, which I do not accept, is that his back pain and right shoulder pain became much worse after the fall and has remained much worse ever since. This evidence is inconsistent with the contemporaneous complaints of pain made to his treating doctors, some of which are recorded above, which indicate that his principal concern was his back, which appears to have borne his weight in the fall. Although it is common ground that he suffered an aggravation to his right shoulder as a result of the fall, I do not accept that such aggravation was structural, significant, or permanent. There is no suggestion that his weight was borne by the right shoulder (as had occurred when he had previously fallen in the bathroom while conscious and apparently endeavoured to break his fall by sticking out his right arm). Indeed the mechanism of the fall from the operating table would suggest to the contrary.
29Although it appears that his back pain was worse for a period after the fall, it is common ground (notwithstanding the plaintiff's evidence) that the aggravation of the back pain was self-limiting and has ceased.
30Although Mr Borg eventually had surgery to repair his right shoulder on 27 March 2007, he said that it only made a "slight difference". I do not accept his evidence. The film taken in 2010 shows that the range of movement of his right shoulder was considerable and that he was able to move it apparently without pain. This represented a very substantial improvement when compared with the description of the restrictions in his right shoulder he gave to Professor Sonnabend when he saw him in August 2006.
31The plaintiff has not sought to make out a case that his right shoulder would have had a better outcome if the surgery had been done five months earlier, which explains the absence of any evidence to support the proposition. In any event I do not consider there to be any proper basis on which to conclude that the long term condition of his right shoulder would have been better if the operation had been performed in November 2006 rather than March 2007.
32Mr Borg gave evidence that, as a result of his limited use of his right shoulder, he used his left shoulder more and it, too, deteriorated.
33It was contended on Mr Borg's behalf that a causal connection between the condition of the left shoulder and the fall had been established on the following basis:
(1)The fall caused the operation to the right shoulder to be deferred for five months.
(2)Mr Borg used the left shoulder more to protect the right for that additional five months.
(3)The additional use of the left shoulder was what caused the left shoulder to be "overused" and this overuse was what made the left shoulder symptomatic.
(4)The left shoulder would not have become symptomatic or required surgery if the operation to the right shoulder had been performed, as scheduled, on 8 November 2006.
34I understood the defendants to accept propositions (1) and (2) above. However, the defendants contended that (3) and (4) had not been established on the balance of probabilities, as required by s 5E of the Civil Liability Act and that, accordingly, the damage to the left shoulder was not compensable in these proceedings.
35The defendants relied on the fact that there is no recorded complaint of pain or other symptoms in the left shoulder until some time after the operation on the right shoulder. Dr Kirsh reported to Dr Moore, Mr Borg's general practitioner, that he would have to remain in an adduction splint for six weeks to allow the repair to heal. The evidence shows that Mr Borg saw Dr Kirsh for review on 4 April 2007, 8 May 2007 and 29 May 2007 without mentioning any difficulties with his left shoulder. I infer from this that he was not suffering pain in the left shoulder during this period.
36The evidence reveals that Mr Borg first complained to Dr Kirsh of left shoulder pain at the review on 17 July 2007, which Dr Kirsh regarded as "no doubt due to overuse". I accept that the pain following overuse was occasioned because of a pre-existing defect in the left rotator cuff which had not previously been symptomatic.
37I accept the defendants' submissions. I am not satisfied that the overuse of the left shoulder that would have been occasioned by the operation had it occurred when scheduled would not have had the same effect as the overuse that occurred when the operation was in fact performed. The plaintiffs have not established to the relevant standard that the five months' delay made any material difference to the onset or extent of symptoms in his left shoulder.
38Mr Borg had an operation on his left shoulder in December 2007 to repair the rotator cuff, which was successful and restored full range of movement.
39Although I accept that Mr Borg has some aversion to hospitals and intense medical treatment as a result of the fall from the operating table, nonetheless he has been prepared to submit to surgical procedures and numerous encounters with medical practitioners since the fall. The defendants do not dispute that he suffers some anxiety as a result of having to undertake these procedures. Nonetheless the anxiety he suffers does not appear to prevent, or otherwise affect, their timely occurrence.
40Mr Borg's right shoulder continued to trouble him because of the lack of active external rotation. On 27 June 2008 Professor Sonnabend reported to Dr Kirsh that Mr Borg had told him that he had difficulty with some minor activities "such as shaving or getting a gun from a holster". The circumstances under which the latter activity was sought to be performed were not explored in the proceedings but it may be related to his former occupation as a security guard.
41On 12 February 2013 Mr Borg had a further operation to his left shoulder that involved arthroscopy, cuff repair and bursectomy.
42In early 2013 Dr Kirsh gave Mr Borg a cortisone injection in his right shoulder for what appears to be the first time. Mr Borg reported that it gave him relief that lasted at least until about May 2013. His right shoulder was reinjected in July 2013 and both shoulders appear to have been injected with cortisone shortly before Christmas.
43Although Mr Borg has had three operations since he fell from the operating table, he gave evidence that it was difficult for him to undertake them because of the stress occasioned by the fall and his resultant fear of doctors and hospitals. He said that he is now scared of heights, apparently because of the fall.
44In his statement (dated 4 February 2013 but signed on 3 October 2013), which he adopted in the witness box, Mr Borg described extreme disability. He instanced a recent attempt to peel potatoes which resulted in pain in his back and shoulders and a shooting pain down his legs, although he had only been standing at the kitchen sink for about 5 to 10 minutes. He said that he tried to mow the nature strip outside his house. He said that it took a long time and he was in severe pain for the next two days. He also said that he had had to attend two doctors' appointments in one day and that he had had to take Endone to help get him through the day and had to lie down in the car between appointments. I do not accept this evidence.
45Mr Borg continues to be paid workers compensation payments as a result of the injuries to his right shoulder and to his back. In the period immediately prior to 20 November 2013, he was paid at the rate of $130.62 under s 37 of the Workers Compensation Act 1987 (NSW). On 19 November 2013, the rate at which he was paid increased to about $940 per week, of which CGU (the insurer responsible for the 2004 right shoulder injury) paid 80% and Allianz (the insurer responsible for the 1988 back injury) paid 20%.
