摘要：

动力髋螺钉(DHS)系统和髓内钉(IMN)系统是治疗骨质疏松性股骨转子间骨折的常规方法,但对骨质疏松性老年患者会产生很多并发症,这与骨质疏松骨折和固定方式的生物力学特点有关。经皮加压钢板(PCCP)和Talons钢板系统不适合严重骨质疏松患者;锁定加压钢板(LCP)-DHS能降低固定失败的危险性,可用于一般情况较差、骨质疏松和骨折稳定性较差患者;Medoff滑动钢板(MSP)具有最好的应力传导优势,但其固定强度较弱。InterTan系统髓内钉、股骨近端防旋髓内钉(PFNA)、转子固定钉(TFN)、可膨胀髓内钉等均有较稳定的效果。对于不稳定型股骨转子间骨折,尤其是老年骨质疏松性骨折患者,IMN系统优于DHS系统,其手术时间短,创伤较小,更适合于此类人群。
