| 摘 要： | 背景:动力髋螺钉置入治疗股骨转子间骨折选择不锈钢还是钛合金材料一直无明确定论。目的:比较不锈钢动力髋螺钉和钛合金动力髋螺钉置入治疗股骨转子间骨折的生物相容性。方法:2003-07/2009-10收治股骨转子间骨折86例,分别用不锈钢动力髋螺钉和钛合金动力髋螺钉治疗各43例,两组患者在性别、年龄、致伤原因、骨折分型等方面基本相同,不锈钢动力髋螺采用00Cr18Ni14Mo3不锈钢,钛合金动力髋螺钉采用Ti6A14V钛合金,比较两组固定后的并发症、髋关节功能的恢复情况,取钉时大体观察植入物周围软组织炎症反应、增生及纤维囊壁情况。结果与结论:两组固定后并发症、髋关节功能的恢复方面差异无显著性意义,但在取钉时大体观察内固定周围软组织炎症反应、增生及纤维囊壁情况,不锈钢动力髋螺钉组明显多于钛合金动力髋螺钉组(P<0.01)。提示钛合金动力髋螺钉的生物相容性好于不锈钢动力髋螺钉,可作为永久性置入材料。
