Nineteen patients who had hip arthroplasties for complications of internal fixation of intertrochanteric fractures were reviewed. There were 6 males and 13 females. The mean age was 64.1 years (range, 21-87 years) at the time of the fracture. The average interval from fracture to arthroplasty was 40.3 months (range, 2-288 months). The prosthesis types included 16 total hip arthroplasties and 3 bipolar hip arthroplasties. A standard femoral stem was used in every patient, and although the stem length did not extend well beyond the most distal screw holes, there was no stress fracture. Complications such as intraoperative fracture of the greater trochanter and postoperative dislocation were common. The Harris Hip Score significantly improved from 38.4 points before the conversion to 79.8 points after an average follow-up of 7.4 years (range, 2-18 years). There was no revision for mechanical failure.
对19例因股骨粗隆间骨折内固定并发症而行髋关节置换术的患者进行了回顾性研究。其中男性6例，女性13例。骨折时的平均年龄为64.1岁（范围21 - 87岁）。从骨折到关节置换的平均间隔时间为40.3个月（范围2 - 288个月）。假体类型包括16例全髋关节置换术和3例双极髋关节置换术。每位患者均使用标准股骨干，尽管股骨干长度未很好地延伸至最远端螺钉孔之外，但未发生应力性骨折。术中大转子骨折和术后脱位等并发症很常见。Harris髋关节评分从转换前的38.4分显著提高到平均随访7.4年（范围2 - 18年）后的79.8分。没有因机械故障而进行翻修。
