“There was no evidence of trunnionosis. The cup was found to be retroverted and the anterium of the cup was prominent and was catching on the anterior structures. There were no signs to suggest wear of the head of the metal liner. The cup was well fixed and I removed it… The stem was found to be well fixed and therefore I elected to leave it in situ.”
'I myself would prefer to put it this way, that he is not guilty of negligence if he has acted in accordance with a practice accepted as proper by a responsible body of medical men skilled in that particular art . . . Putting it the other way round, a man is not negligent, if he is acting in accordance with such a practice, merely because there is a body of opinion who would take a contrary view.'
“… in my view, the court is not bound to hold that a defendant doctor escapes liability for negligent treatment or diagnosis just because he leads evidence from a number of medical experts who are genuinely of opinion that the defendant's treatment or diagnosis accorded with sound medical practice. In the Bolam case itself, McNair J. [1957] 1 W.L.R. 583, 587 stated that the defendant had to have acted in accordance with the practice accepted as proper by a ' responsible body of medical men.' Later, at p. 588, he referred to 'a standard of practice recognised as proper by a competent reasonable body of opinion.' Again, in the passage which I have cited from Maynard's case [1984] 1 W.L.R. 634, 639, Lord Scarman refers to a 'respectable' body of professional opinion. The use of these adjectives - responsible, reasonable and respectable - all show that the court has to be satisfied that the exponents of the body of opinion relied upon can demonstrate that such opinion has a logical basis. In particular in cases involving, as they so often do, the weighing of risks against benefits, the judge before accepting a body of opinion as being responsible, reasonable or respectable, will need to be satisfied that, in forming their views, the experts have directed their minds to the question of comparative risks and benefits and have reached a defensible conclusion on the matter.”
“… an entry is made into the top end of the femur, with the entry point being important for the orientation of the femoral component… The femur is then broached to compact the cancellous bone (spongy) and when rotational stability is achieved with a trial broach then it is reasonable to stop broaching in this particular system. With the trial broach in place and either the definitive liner inserted into the cup or a trial liner, a trial is performed to assess for leg length, offset and stability. When the surgeon is satisfied that the trial is satisfactory, a definitive stem is inserted and normally a further trial is performed. The appropriate head is then secured to the femoral component”
