Comprehensive Summary

Summary of Judgment

1. Introduction

The proceedings were an appeal to a full court of the Gauteng Division, Local Seat, Johannesburg, arising from a delictual claim for damages based on an alleged negligently performed right total hip replacement at a state hospital. The appeal was heard together with an application to reinstate a lapsed appeal.

The appellants were Professor Sebastian Keith McDonald Magobotha (an orthopaedic surgeon and head of a clinical unit at the time) and the Member of the Executive Council responsible for Health and Social Development in the Gauteng Province (the “MEC”). The respondent was Ms R (the plaintiff in the trial court), who sued for damages allegedly arising from complications following the June 2008 procedure.

The procedural history was that Ms R instituted action against Professor Magobotha (first defendant), Dr Peer (second defendant) and the MEC (third defendant). By agreement, the trial court (Van der Linde J) separated quantum from the merits, and heard and determined only negligence and causation. The trial court found in favour of Ms R on those separated issues. Professor Magobotha and the MEC appealed with leave.

The general subject-matter of the dispute concerned whether negligent surgical performance and/or supervision in the insertion of an acetabular component caused Ms R’s subsequent hip dislocations and the chain of events culminating in further surgery and septic complications, and whether such consequences were legally attributable to the alleged negligence.

2. Material Facts

It was common cause that, at the relevant time, Professor Magobotha and Dr Peer were employees of the MEC and acted within the course and scope of their employment. The MEC accepted that, if negligence were proved against either doctor and causation established, the MEC would be vicariously liable for Ms R’s proven damages.

Ms R underwent a right hip replacement at Chris Hani Baragwanath Hospital on 10 June 2008, which was not successful. Ms R’s evidence was that she had been admitted by Professor Magobotha, who undertook that he would perform the operation. She later learnt (in January 2009) that Dr Peer, rather than Professor Magobotha, had performed the surgery. Professor Magobotha’s evidence was that he assumed Dr Peer performed the operation under his direct supervision, but he could not recall details of the surgery and contemporaneous notes and immediate post-operative x-rays were not available.

On Ms R’s unchallenged evidence, about five days after the operation (15 June 2008), Professor Magobotha examined her and pressed on her right leg near the wound, whereupon the wound burst open; he diagnosed an abscess/sepsis and had her admitted to hospital for approximately ten days for treatment of septicaemia. Neither party suggested that Ms R had sepsis prior to 10 June 2008, and the defence did not contradict her account of the wound bursting open and the diagnosis of septicaemia shortly after the operation.

On 11 July 2008, approximately a month after surgery, while standing with crutches, Ms R turned her head to the right, her right leg gave way, and she fell. The hip had dislocated, and on 19 July 2008 Professor Magobotha performed a procedure successfully to relocate the hip. No party contended that this 19 July 2008 procedure caused sepsis.

In October 2009, because of severe pain, Ms R consulted a private orthopaedic surgeon, Dr Steyn, who performed two right hip operations in October and November 2009 at Glynwood Hospital. Ms R’s evidence was that Dr Steyn performed the second procedure because he advised her there was an infection and the hip had dislocated again.

Expert evidence for Ms R (Professor Van Der Jacht) relied on x-rays taken at Baragwanath on 4 July 2008, which showed that the acetabular component had been inserted at approximately 80 degrees to the horizontal, whereas (on his evidence) it should be inserted at about 45 degrees to promote stability and reduce wear. A minute authored by Professor Van Der Jacht, recording a meeting with the defendants’ retained expert (Professor Lukhele, who did not testify), reflected agreement that the operation was not optimally performed, that incorrect positioning of the acetabular component would likely have prevented dislocation and the need for revision procedures, and that the experts could not determine from available information whether later septic sequelae were consequences of the Baragwanath surgery or later private surgery.

The court treated as material that neither side’s pleadings raised sepsis as an issue, but that the evidence nonetheless included Ms R’s unchallenged account of early post-operative septicaemia and the later infection described in connection with Dr Steyn’s second procedure.

3. Legal Issues

The central legal questions the full court was required to determine were whether the trial court correctly held that there was negligence in the performance and/or supervision of the 10 June 2008 hip replacement (particularly the positioning of the acetabular cup), and whether that negligence was a legally relevant cause of Ms R’s subsequent harm.

A further central issue was the role of sepsis/infection in the causal chain, specifically whether septic complications broke the chain of causation or constituted intervening events, and whether the later infection associated with Dr Steyn’s procedures affected legal responsibility for the ultimate outcome.

These issues involved a combination of fact (what occurred during and after surgery; the cup’s positioning; the timing and onset of infection), application of law to fact (factual causation and legal causation), and an evaluative component in determining whether there was a sufficiently close connection between the negligent act (if established) and the later harm.

In addition, the court had to decide whether to reinstate a lapsed appeal, a procedural issue dependent on explanation for delay, prejudice, and the discretionary management of appellate procedure.

4. Court’s Reasoning

On negligence relating to the surgical procedure, the court treated the expert evidence about optimal acetabular cup positioning as central. It accepted that the cup should be positioned within a stability-promoting range (described by Professor Magobotha as between 40 and 60 degrees, and by Professor Van Der Jacht as about 45 degrees) and that, on the available x-rays, the cup was inserted at a markedly steeper angle (about 80 degrees). The court regarded this mal-alignment as significant to hip instability and the occurrence of dislocation.

The court considered Professor Magobotha’s evidence that he could not recall the procedure and that immediate post-operative x-rays and contemporaneous notes were missing. While accepting that his inability to remember was understandable given the volume of procedures, the court held that this left his evidence of limited value. It did not accept that the absence of immediate x-rays precluded a conclusion on malposition; it treated the later x-rays as sufficient to support the inference of incorrect insertion, particularly in the context of the expert evidence.

On sepsis, the court drew a distinction between inferring negligence from a poor outcome and assessing causation where infection occurs. It expressly cautioned against assuming negligence merely because sepsis followed surgery, and noted that neither Professor Van Der Jacht nor Professor Lukhele suggested negligence in relation to sepsis itself. The experts’ criticism was directed to the malpositioning of the cup, and the minute recorded that they could not determine whether septic sequelae flowed from the initial state-hospital surgery or later private surgery.

Despite this, the court placed weight on Ms R’s credible, unchallenged evidence that the wound burst open and septicaemia was diagnosed within five days of the 10 June 2008 operation, and that she required re-admission and treatment. Because the defence did not challenge or contradict this evidence, and because neither party suggested a prior sepsis problem, the court held that the “only plausible inference” was that it was probable that the sepsis started during the 10 June 2008 operation.

The court then addressed the causation debate concerning the later infection associated with Dr Steyn’s interventions. It reasoned that the fifteen-month interval between July 2008 and October 2009 made it “most improbable” that an infection originating from the earlier state-hospital surgery would have remained undetected until October 2009. On Ms R’s evidence that Dr Steyn’s second operation was prompted by infection, the court inferred that the infection problem at that stage could only have arisen during the first of Dr Steyn’s procedures. However, the court did not treat this as excluding liability for the earlier malposition.

In dealing with the interplay between malposition, dislocations, repeat procedures, and infection risk, the court reasoned that the mal-alignment in June 2008 was a cause in fact of the subsequent dislocations and that those dislocations gave rise, predictably, to the need for further surgical interventions. It treated the need for additional surgery as reasonably increasing exposure to infection risk, and held that there was a reasonable connection between the initial mal-alignment and subsequent sepsis—both the early sepsis shortly after the 10 June operation and the later infection after the October 2009 procedure—because the later events were linked to the corrective pathway initiated by the initial malposition and instability.

In reaching this conclusion, the court indicated that it was not bound by the expert’s statement that sepsis did not “come into it at this stage”, particularly given the contrary weight of reliable evidence on early post-operative infection, and it referred to authority concerning the court’s role in evaluating expert opinion against the broader evidentiary record. It also applied a flexible approach to causation by asking whether there was a sufficient, reasonable connection between the initial negligent act and the harm ultimately suffered.

On Professor Magobotha’s liability, the court held that he was liable because he was present and in a supervisory role when the cup was fitted. Given the common-cause vicarious liability position, the MEC’s liability followed if negligence and causation were established.

On reinstatement, the court accepted that the appellants’ attorney had requested the record promptly after leave to appeal, that the delay in obtaining the record was not attributable to the appellants’ attorney, and that some delay was linked to a Rule 30 irregular proceeding notice delivered and later withdrawn by the respondent’s attorney. It concluded that reinstatement should be granted, that there was no prejudice to Ms R, and that while the merits were reasonably arguable, reinstatement remained an indulgence. The court considered the respondent’s opposition reasonable and recorded that counsel for the appellants tendered costs for the reinstatement application. It further dealt with costs consequences of an earlier postponement on 24 October 2018, ordering those costs to be costs in the cause.

5. Outcome and Relief

The court ordered that the lapsed appeal be reinstated.

It ordered that the appellants pay the respondent’s costs of the reinstatement application on an opposed basis, jointly and severally.

On the merits, the court dismissed the appeal with costs, holding the appellants jointly and severally liable for those costs. The costs order included the wasted costs of 24 October 2018, which were treated as costs in the cause.

Held

The court held that the acetabular component inserted during the 10 June 2008 hip replacement was malpositioned at a markedly non-optimal angle, that this mal-alignment caused subsequent hip instability and dislocations, and that the ensuing need for further corrective procedures created a reasonably connected pathway to septic complications. It held that Professor Magobotha, as a supervisory presence when the cup was fitted, was liable, and that the MEC was vicariously liable on the common-cause employment position.

The court further held that the lapsed appeal should be reinstated, but that the appellants were to bear the costs of the reinstatement application as an opposed indulgence, and that the merits appeal itself should be dismissed with costs.

LEGAL PRINCIPLES

A court is not bound to accept an expert’s opinion where the reliable evidentiary record points in another direction; expert evidence must be weighed against proven facts and probabilities, and unchallenged credible lay evidence may justify factual inferences.

Negligence should not be inferred merely from a poor outcome (such as post-operative infection); the enquiry remains whether the conduct fell short of the standard of reasonable professional care, assessed on the evidence presented.

In causation, where an initial wrongful act necessitates further medical interventions, the court may consider whether there is a reasonable connection between the initial act and later harm, including harm arising through foreseeable risks associated with additional procedures (such as increased infection risk), applying a flexible approach to legal causation.

Where medical professionals are acting within the course and scope of employment, and negligence and causation are established, the employing authority may bear vicarious liability for the resulting damages, on the basis accepted as common cause in the proceedings.

An application to reinstate a lapsed appeal involves an evaluative discretion informed by the explanation for delay, absence or presence of prejudice, and the fact that reinstatement is an indulgence; costs may be awarded against the party seeking reinstatement notwithstanding arguable merits.
