| Summary: | 碩士 === 中山醫學院 === 醫學研究所 === 87 === To demostrate the clinical experience of hemiarthroplasty of hip at the Department of Orthopedics, Chung Shan Medical & Dental college hospital, 203 patients with 206 hemiarthroplasty of hip between January, 1978 and December, 1994 were collected & analyzed through review of medical records and clinical follow-up. Finally, there were 156 patients with 156 hemiarthroplasty included in this study and divided into two group: 93 patients with 93 hemiarthroplasty in Austin-Moore group and 60 patients with 63 hemiarthroplasty in bipolar group. For Austin-Moore group, the average age was 65.5±11.3 years and 90.3% of case were femoral neck fractures, while was 60.5±15.5 years and 87.3% in the bipolar group. The average operate time, blood loss, and duration of hospital stay for Austin-Moore group were all significently less than those in bipolar group. Both groups had a high satisfactory result base on Harris hip scores, though there was a higher incidence of Acetabular erosion in Austin-Moore. We concluded that Austin-Moore will be the choice for displaced femoral neck fracture of the elderly with poor medical conditions, while Bipolar endoprosthesis will be used for the elderly with stable medical conditions or avascular necrosis of femoral head with a decreased incidence of acetabular erosion.
