Abstract

Forty five patients above the age of 60 with displaced femoral neck fractures were treated by bipolar hemiarthroplasty in Kangbuk Samsung hospital from January 1990 to January 1995. We evaluated these patients for comparison of the results between the cemented and uncemented femoral fixation, especially in elderly patients with medical illness or osteoporosis. During a follow up period of more than two years, the authors found less thigh pain(5.2% versus 38%) and slightly higher Harris hip scores(84.5 versus 80.0 points) in the cemented group in comparison with the uncemented group. Radiographic examination showed less radiolucent zones in the cemented group. Comparing the operative time(86.2 versus 83.8 minutes), hospital stay(4.7 weeks versus 5.3 weeks), blood loss(385 versus 381 ml) during the operation. The postoperative mortality rate was 2%, and the follow-up mortality rate was 11% in the first year. There was no significant difference between two groups in mortality rate. Thus in bipolar hemiarthroplasty in elderly patients with displaced femoral neck fracture, we have obtained satisfactory results despite of poor bone condition and osteoporosis except thigh pain. But the follow up period was too short to assess the late complications of the hemiarthroplasty such as acetabular erosion, implant loosening, so long-term follow up will be necessary
