Abstract
Introduction: Hip resurfacing has undergone a resurgence of interest in the past five years. With it, the awareness of femoral neck fractures associated with this prosthesis has grown. We report the first national review of femoral neck fractures over a four-year period.
Method: All surgeons using the Birmingham hip resurfacing in Australia were contacted and asked to supply details of any femoral neck fractures they had experienced. Routine co-morbidities and demographics were collated.
Results: Fifty fractures have occurred in the time period. The fracture rate was twice as high in women than men and this was statistically significant (p< 0.001). Mean time to fracture was 15 weeks and was slightly longer in women than men. Technical difficulties included notching of the femoral neck, varus placement of the femoral prosthesis, poor exposure due to obesity and poor impaction of the femoral component.
Conclusions: The national fracture rate associated with the Birmingham hip resurfacing is 1.46%.
