120 elderly patients with acute displaced femoral neck fractures were randomized to treatment with either a bipolar hemiarthroplasty or a total hip arthroplasty. Differences in the hip function and health related quality of life were measured at 4/12/24/48 months post operation. The results from this trial indicate that patients who received total hip arthroplasty presented with better hip function at all time points and the health related quality of life was significantly improved at 48 month follow-up in these patients.
