Secondary arthroplasty for complications of femoral neck fracture.
We report a series of 640 consecutive cervical hip fractures which were followed prospectively for two years after primary internal fixation with two hook-pins. Secondary arthroplasties were performed as salvage procedures in 75 cases and the early outcome of these was studied retrospectively. The mean time in hospital was 25 days for prosthetic replacement, though 60% of the patients had other medical conditions considered as risk factors. Mortality was 5% after six months and 8% after one year. Dislocation was seen in 11% and additional surgery was required in 4%. There was one case of deep infection and one supracondylar femoral fracture. In some cases there was considerable delay between the primary and secondary operation due to lack of awareness of functional deterioration, but although many patients had poor mobility before the secondary operation this was greatly improved within six weeks of the arthroplasty. We conclude that elective secondary hip arthroplasty for failure of fracture fixation is a safe and successful procedure. Once the decision to perform an arthroplasty is taken, this should be done without delay to avoid deterioration of function.
