经皮空心加压螺钉内固定术治疗老年人股骨颈骨折57例临床分析

目的 观察经皮空心加压螺钉内固定治疗股骨颈骨折的临床效果.方法 102例股骨颈骨折患者随机分为两组,观察组57例采用经皮空心加压螺钉内固定治疗,对照组45例采用人工全髋关节置换术,比较两组的骨折愈合率.结果 术后随访时间6个月至3年,平均（2.3±0.7）年,无钉孔感染或因手术死亡病例.功级评定：观察组优16例、良25例、差8例、愈合率86.6%,对照组分别为8例、9例、14例、68.9%,两组愈合率差异有统计学意义（x2=4.33,P＜0,05）.两组股骨头缺血坏死率,差异无统计学意义（x2=1.91,P＞0.05）.结论 经皮空心加压螺钉内固定治疗股骨颈骨折,安全有效,能够明显提高患者骨折愈合率.

Clinical effect of internal fixation with hollow compression screw for old patients with femoral neck fracture

Objective To observe the clinical effect of internal fixation with hollow compression screw for old patients with femoral neck fracture.Methods 102 old patients with femoral neck fracture were randomly classified into two groups,which observation group with 57 cases were treated with internal fixation with hollow compression screw and control group with 45 cases were treated with total hip replacement.The clinical effect between the two groups were compared.Results The effective rate in observation group was significantly higher than that in control group(x2=4.33,P＜0.05).There was no significant difference in avascular necrosis between the two groups(x2=1.91,P＞0.05).Conclusion Internal fixation with hollow compression Screw for old patients with femoral neck fracture Was safe and can improve clinical effect,which could be applied in clinic.
