Comparison of bipolar hemiarthroplasty with total hip arthroplasty for displaced femoral neck fractures: a concise four-year follow-up of a randomized trial
J Bone Joint Surg Am. 2011 Mar 2;93(5):445-50120 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, and 48 months post operation. The results from this trial indicated 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 4 year (48 months) follow-up in these patients.
