摘要
目的探讨加压空心钉内固定治疗股骨颈骨折,取出空心钉后发生股骨头坏死的可能影响因素。方法 1997年1月至2009年12月,本组收治363例股骨颈骨折患者,其中采用加压空心螺钉内固定者233例,获得随访并最终取出空心钉者157例,统计分析发生股骨头坏死例数及相关因素的相关性。结果经24～60个月的随访,影像学评估加临床症状证实,本组发生股骨头坏死24例。影响股骨头坏死的因素:股骨头坏死发生与性别(女性)、年龄(60岁以上),骨折分型(Ⅲ,Ⅳ型),骨密度(≤-2.5SD)、复位质量呈显著相关。结论股骨颈骨折应尽量达到解剖复位,必要时须行开放复位。对于GardenⅢ、Ⅳ型股骨颈骨折,和由各种因素引起的骨密度下降(骨质疏松)患者,关节置换可能是一种更为理想的治疗方式。
Objective To find out factors related to avascular necrosis （AVN） of femoral head after the cannulated screws has been removed. Methods In our department from January 1997 to December 2009, 157 cases of femoral neck fracture were treated with cannulated screws which had been removed later on. All these patients were followed up and analyzed statistically by rank sum test and logistic multiple regression. Results Factors that might have an impact on avascular necrosis of femoral head were： gender, age, fracture type, bone mineral density, and quality of reduction. Conclusions Femoral neck fracture should have anatomic reduction by open reduction when necessary. For patients of Garden Ⅲ and type Ⅳ femoral neck fracture, and decreased bone mineral density caused by various factors （osteoporosis） patients, joint replacement may be a more ideal treatment.
