不同时间段空心加压螺钉内固定治疗老年移位型股骨颈骨折疗效分析

目的 比较急诊与延期行空心加压螺钉内固定术治疗老年移位型股骨颈骨折的临床效果。方法 回顾性分析2000年12月～2010年12月我院采用空心加压螺钉内固定治疗股骨颈骨折的患者99例，分成急诊组52例，延期组47例，比较术后的骨折复位质量、骨折愈合情况，术后1年、2年股骨头缺血坏死、塌陷发生率以及髋关节功能情况及全身并发症等治疗效果的差异性。结果 骨折愈合率、股骨头坏死率、髋关节功能优良率、急诊组股骨头坏死率较延迟组高，两组间均有显著性差异（P<0.05）。结论 对于老年移位型股骨颈骨折患者，采用闭合复位空心加压螺钉内固定治疗，急诊手术疗效优于延期手术。

Efficacy analysis of hollow compression screw internal fixation for the treatment of senile displaced femoral neck fractures at different time

Objective To compare the efficacy of hollow compression screw internal fixation for the treatment of senile displaced femoral neck fractures between emergency operations and delayed operations. Methods The clinical data of 99 patients, who received hollow compression screw internal fixation for the treatment of femoral neck fractures from December 2000 to December 2010, were analyzed retrospectively. The patients were divided into emergency group (n=52) and delayed group (n=47). The postoperative fracture reduction, fracture healing, avascular necrosis of the femoral head, the incidence of collapse, the function of hip joint, and systemic complications 1 year and 2 years after the operation were compared. Results The rate of fracture healing, the rate of avascular necrosis of the femoral head, and the excellent rate of the hip joint function, the rate of the femoral head necrosis were higher in emergency group than those in the delayed group, and the difference between the two groups was significant (P<0.05). Conclusion For senile patients with displaced femoral neck fractures, the efficacy of closed reduction with hollow compression screw fixation of emergency operation is superior to that of delayed operation.
