Evaluated 4 consultants learning a procedure. The learning
curve was longer expected with implications for proposed
shortened training programmes and a reduction in operative
experience.
With shortened training programmes advocated, we have
established a learning curve for hip resurfacing in
experienced consultants.
We prospectively planned the placement of a hip resurfacing
prosthesis. Using CUSUM analysis we established how long it
took for consistent placement of the prosthesis to take
place.
4 experienced surgeons learning the hip resurfacing
procedure were included. Thus negating the need to learn
basic surgical skills. Evaluating the first 100 cases of
each, showed that the learning curve between planned and
achieved implant position was in the order of 50 cases.
The learning curve was longer than estimated and has huge
implications, with shortened training programmes and less
operative exposure being advocated throughout the world.
