Abstract
The authors studied the short-term outcomes of total hip arthroplasty (THA) performed using large diameter femoral heads or bipolar arthroplasty (BA) in physiologically active elderly patients with displaced intracapsular femoral neck fractures. The THA group included 14 males and 66 females with a mean age of 75.5 years, and the BA group included 16 males and 73 females with a mean age of 77.6 years. Surgical procedures were performed by one surgeon using a modified Hardinge approach. Mean operation times were significantly longer in the THA groups. Pain, mobility, and walking ability scores were significantly better in the THA group than in the BA group. Despite no range of motion limitation during the early postoperative period, no dislocation was encountered in either group. The present study suggests that for displaced femoral neck fractures, THA with a large diameter femoral head results in less pain and better function than BA.
