Failure of internal fixation of intertrochanteric fractures is associated with delayed union or malunion resulting in persistent pain and diminished function. We evaluated 15 elderly patients treated with a tapered, fluted, modular, distally fixing cementless stem. At an average follow-up of 2.86 years, mean Harris hip score improved from 35.90 preoperatively to 83.01 (P < .01). Fourteen stems had stable bony on growth, and one stem was loose. Distal fixation with a tapered, fluted, modular cementless stem allows stable fixation with good functional outcome in a reproducible fashion in this challenging cohort of patients.
股骨转子间骨折内固定失败会导致延迟愈合或畸形愈合,从而引起持续疼痛和功能减退。我们评估了 15 名使用锥形、开槽、模块化、远端固定非骨水泥柄治疗的老年患者。平均随访 2.86 年后,Harris 髋关节评分从术前的 35.90 分提高到 83.01 分(P<.01)。14 个柄有稳定的骨长入,1 个柄松动。使用锥形、开槽、模块化非骨水泥柄进行远端固定,可以以可重复的方式在这一具有挑战性的患者群体中实现稳定固定和良好的功能结果。
