摘要
目的：比较动力髋螺钉（ DHS）和股骨近端髓内钉（ PFN）治疗股骨转子间不稳定型骨折的疗效。方法56例股骨转子间不稳定型骨折患者按手术方法分为DHS组（28例）和PFN 组（28例），对两组疗效进行比较。结果56例均获得随访，时间6∽38个月。术后并发症：DHS组深静脉血栓形成3例，压疮3例，伤口感染2例，肺炎2例，内固定松动1例，骨不连后髋内翻畸形2例，发生率13/28；PFN组深静脉血栓形成1例，压疮2例，肺炎1例，骨不连1例，发生率5/28；两组比较差异有统计学意义（ P〈0．05）。髋关节功能Harris评分：DHS组优18例，良2例，中5例，差3例，优良率20/28；PFN组优24例，良2例，中1例，差1例，优良率26/28；PFN组优良率高于DHS组（P〈0．05）。结论 PFN治疗老年股骨转子间不稳定型骨折较DHS有更好的优良率、更低的并发症发生率。
Objective To compare the efficacy of unstable intertrochanteric fractures treated by using dynamic hip screw （ DHS） and proximal femoral nail （ PFN） . Methods 56 patients with unstable intertrochanteric fractures were divided to dynamic hip screws（DHS） group（28 cases）and proximal femoral nail（PFN）group（28 cases）,and the ef-ficacy of the two groups was compared. Results All patients were followed up for 6∽38 months. Postoperative com-plications in DHS group were deep vein thrombosis for 3 cases, 3 cases of bedsore, 2 cases of wound infection, 2 ca-ses of pneumonia, 1 case with internal fixation loosening, 2 cases of bone nonunion after hip varus deformity, the in-cidence was 13/28;PFN group complications were 1 case of deep vein thrombosis, 2 cases of bedsore, 1 case of pneumonia, 1 case of bone nonunion, the incidence was 5/28;the difference was statistically significant（P〈0. 05）. According to Harris evaluation standard,the excellent-good rate of DHS group was 20/28,18 cases were excellent, good in 2, fair in 5, and poor in 3;the excellent-good rate of PFN group was 26/28, 24 cases were excellent, good in 2, fair in 1, and poor in 1. PFN group was significantly higher than DHS group for the excellent-good rate （ P 〈0. 05）. Conclusions Compared with DHS group, PFN group has better excellent-good rate and lower incidence rate of complications.
