目的探讨锁定加压空心钉方法与经皮加压空心钉内固定治疗股骨颈骨折的疗效比较.方法回顾分析2005年4月至2011年9月我院收治的80例中青年股骨颈骨折患者的临床资料,采取锁定加压空心钉治疗的40例患者作为观察组,采用经皮加压空心钉内固定治疗的40例患者作为对照组.比较两组患者骨折愈合、发生骨不连、股骨头坏死的情况.结果随访18个月后观察组骨折愈合率为75%,明显高于对照组的62.5%,特别是骨无菌性坏死的发生率17.5%,显著低于对照组的27.5%.结论加压空心钉锁定确能有效降低骨无菌性坏死的发生率,促进患者的愈合率,通过良好的内固定方法减少骨不连的发生进而减少骨无菌性坏死的发生是治疗此症的关键.“,”Objective: To discuss the clinical effect of reating middle-young age femoral neck fracture by cannulated screw internal fixation. Methods: Choosed 80 cases of middle-young age femoral neck fracture from Apr. 2005 to Sep. 2011 to divide into study group and controled group with 40 cases in each other. Study group were treated with cannulated screw locked, and controled group were treated with cannulated screw infernal fixed. Compared the fracture healing, nonunion and femoral head necrosis of these two groups. Results:The cure rate in study group was 75% higher than 62.5% in controled group, and the incidence of femoral head necrosis was 17.5% lower than 27.% in controled group. Conclusion:Cannulated screw locked could decrease the incidence of femoral head necrosis and promote healing. It is the key to use better infernal fixed ways to decrease nonunion and femoral head necrosis.
