摘要 目的评价逆行髋臼前柱拉力螺钉内固定治疗髋臼前柱骨折的生物力学结果,探讨其临床应用效果。方法选则成人干燥髋骨标本10对。通过测量髋臼前柱不同截面,确定逆行髋臼前柱拉力螺钉的进针点、进针方向、螺钉直径和长度。采用逆行髋臼前柱拉力螺钉内固定术治疗髋臼前柱骨折患者17例。结果耻骨螺钉进针点位于耻骨嵴中点下方(8.5±0.5)mm处,螺钉长度(71.1±5.7)mm,直径(8.1±0.6)mm;髋臼螺钉进针点位于耻骨前缘闭孔嵴上,距耻骨结节(25.5±2.3)mm,螺钉长(86.8±6.2)mm,直径(9.8±1.0)mm。17例患者疗效满意。结论逆行髋臼前柱拉力螺钉内固定技术固定稳定、可靠,治疗髋臼前柱骨折安全、有效,且创伤小、便于操作。
