股骨近端髓内钉和动力髋螺钉治疗股骨转子间骨折的临床研究

Clinical study of proximal femoral nail anti-rotation and dynamic hip screw in the treatment of femoral intertrochanter fractures

目的:研究比较股骨近端髓内钉(PFNA)和动力髋螺钉(DHS)治疗股骨转子间骨折的临床疗效。方法:选择2012年1月至2013年12月间因单侧股骨转子间骨折于我院住院行PFNA及DHS手术治疗的患者312例,其中192例采用PFNA内固定,120例采用DHS内固定,记录手术时间、术中出血量、术后3 d VAS评分、住院时间、Harris评分,并将所记录的结果进行统计分析。结果:PFNA和DHS两组的手术时间之间差异有统计学意义,而术后3 d的VAS评分、住院时间及术后1年的Harris评分差异均无统计学意义,术中出血量的差异性仍需要进行进一步求证。结论:PFNA和DHS两种内固定方法治疗股骨转子间骨折时,手术时间PFNA优于DHS,而临床疗效两者无明显差异。

Objective： To compare the clinical effect on the treatment of femoral intertrochanter fractures with proximal femoral nail anti-rotation（ PFNA） and dynamic hip screw（ DHS）. Methods： A retrospective study with312 cases of unilateral femoral intertrochanter fractures from January 2012 to December 2013 were carried out,192 cases were treated with PFNA,while 120 cases with DHS. The data of operative time,blood loss,postoperative VAS score,hospitalization time and Harris score were recorded and statistically analyzed. Results： There were significant differences in operative time between two groups,no significant differences in VAS score,hospitalization time and Harris score,the differences of blood loss still needed further confirmation. Conclusion： In the treatment of femoral intertrochanter fractures with two methods,PFNA is superior to DHS in the operative time,but there are no significant differences in clinical effect.
