摘要 目的对动力髋螺钉(DHS)及股骨近端髓内钉(PFN)内固定股骨粗隆间骨折失败的原因进行分析,为临床应用DHS和PFN内固定治疗股骨粗隆间骨折提供理论依据。方法回顾性分析自2003-08—2008-12采用DHS和PFN内固定治疗股骨粗隆间骨折术后发生内固定失效的15例临床资料,总结失效原因。结果 DHS头颈加压钉切割出股骨颈、侧板拔出3例,髋内翻4例,头颈钉自滑槽滑出2例,头颈钉断裂1例,DHS钢板断裂1例,DHS钢板固定螺钉断裂2例;PFN髓内钉断裂1例,PFN髓内钉近端锁钉切割1例。结论骨折复位不良、内固定选择不当、螺钉位置不正、骨质疏松等因素均可导致DHS和PFN内固定失效,术前全面分析、术中精确操作是保证DHS和PFN内固定手术成功的关键。
