人工股骨头置换治疗股骨颈骨折远期随访结果

Long-Term Results of Hemiarthroplasty for Femoral Neck Fractures Long Term Results in 62 cases.

作者１９８０～１９８５年主要以Ａｕｓｔｉｎ－Ｍｏｏｒｅ型人工股骨头治疗９０例股骨颈骨折。随诊８年以上６２例，手术时平均年龄６４．７岁，平均随诊１０年７个月，疗效满意率９６．８％。３７例Ｘ线片检查：１９例髋臼完好，１５例髋臼缘骨质增生，中心性脱位３例占８．１％。３０例有系列Ｘ线片者，下沉２１例占７０％，多数为轻度下沉。随诊结果说明：单极人工股骨头长期使用并不造成中心性脱位，髋臼缘骨质增生与负重使用相关，中心性脱位与头臼比例不当，应力集中相关。

Of 90 cases underwent hemiarthroplasty for femoral neck fracture from 1980 to 1985, 62 cases were followed up more than 8 years, with an average of ten years and seven months. The average age of the patients at the surgery was 64.7 years. Sixty cases were treated with Austin-Moore prosthesis. 96.8% of the patients had excellent or good results at the final follow up study. Radiological examinations showed that 19 cases had perfect acetabula, 15 cases had acetabular osteophytes and only 3 cases (8.1%) had pelvic central protrusion. Thirty cases had serial roentgenograms, there were 21 cases(70%) with stem sinking. The long term results indicate that hemiarthroplasty does not cause acetabular erosion. Acetabular osteophytes is related to weight bearing, while acetabular erosion is possibly due to unsuitable prostheses selection.
