摘要 目的比较分析动力髋螺钉(Dynamic Hip Screw,DHS)和防旋股骨近端髓内钉(Proximal femoral nail antirotation,PFNA)治疗老年股骨转子间骨折的疗效。方法 68例老年股骨转子间骨折患者按治疗方法分为两组将,每组各34例。采用DHS内固定为DHS组,采用PFNA内固定为PFNA组。对比分析两组患者性别、年龄、手术时间、术中失血量、隐性失血量、卧床时间、负重活动时间、住院时间、并发症发生率、术后骨折愈合时间、术后髋关节功能评分等。结果两组患者在年龄、性别、骨折类型方面比较差异均无统计学意义。经过平均16个月随访,DHS组有5例内固定失败,PFNA组有3例不愈合或延迟愈合。PFNA组较DHS组在手术时间,术中出血,骨折愈合时间,术后并发症发生率,术后髋关节Harris评分方面有优势,但术后隐性失血多(<0.05)。两组术后卧床时间、负重活动时间、住院时间、总失血量比较差异无统计学意义。结论采用DHS和PFNA治疗股骨粗隆间骨折都可以获得良好效果。PFNA较DHS创伤小、术后并发症少、术后髋关节功能恢复好,适用于各种类型尤其是不稳定型股骨粗隆间骨折或严重骨质疏松患者。
