动力髋螺钉和股骨近端髓内钉两种内固定方式治疗老年股骨粗隆间骨折临床疗效

目的：比较动力髋螺钉（DHS）和股骨近端髓内钉（PFN）两种内固定方式治疗68例老年股骨粗隆间骨折临床疗效。方法：将68例股骨粗隆间骨折老年患者随机均分为两组，分别采取DHS和PFN不同内固定方式进行治疗，比较两组的术中出血量、手术时间、术后疗效及术后并发症发生率。结果：PFN组的优良率为91．18％，明显高于DHS组的70．59％（P=0．031〈0．05）；PFN组的术中出血量、手术时间及愈合时间均优于DHS组（P均〈0．05）。PFN组的并发症发生率为2．94％，低于DHS组的17．65％（P=0．046〈0．05）。结论：PFN较DHS固定方式治疗老年股骨粗隆间骨折更有效，并发症少，安全性大。

Clinical Efficacy of DHS and PFN in the Treatment of Elderly Intertrochanteric Fracture

Objective： To compare the clinical efficacy of DHS and PFN in the treatment of 68 cases of elderly intertrochanteric fracture. Methods： 68 cases of elderly intertrochanteric fracture were randomly divided into two groups,were taken with two different fix- ation methods： DHS and PFN,and compared the blood loss, operative time, postoperative efficacy and the incidence of postoperative complications. Results： The excellent rate in PFN group was 91.18%, significantly higher than 70.59% in DHS group（P=0.031〈0.05）. The blood loss, operation time and healing time in PFN group were better than that in DHS group （P〈0.05）. The incidenceof complica- tions in PFN was 2.94%, lower than 17.65% in the DHS group （P=0.046〈0.05）. Conclusion： Compare with DHS fixation, PFN in the treatment of elderly intertrochanteric fracture is more effective, fewer complications and security.
