The purpose of this study was to compare the clinical and radiographic results for elderly patients sustaining unstable intertrochanteric fractures treated with an uncemented bipolar hemiarthroplasty using a double-tapered, rectangular cross-section stem. Thirty-seven patients (21 females, 16 males; mean age 73.5 years, range 65-88 years) who underwent bipolar hemiarthroplasty with a standard (double-tapered, rectangular cross-section) uncemented stem were followed up for a minimum of two years. At final follow-up, 27 patients (72.9%) had recovered their daily living ability (Barthel index), and 28 patients (75.6%) had recovered all walking ability at a community level (Koval's category).
本研究的目的是比较使用双锥形矩形横截面柄的非骨水泥型双极半髋关节置换术治疗老年不稳定型股骨转子间骨折的临床和影像学结果。对37例患者（21例女性，16例男性；平均年龄73.5岁，范围65 - 88岁）进行了标准（双锥形矩形横截面）非骨水泥柄双极半髋关节置换术，并至少随访两年。在末次随访时，27例患者（72.9%）恢复了日常生活能力（Barthel指数），28例患者（75.6%）恢复了社区水平的所有行走能力（Koval分级）。
