DHS和PFNA治疗老年骨质疏松性股骨转子间骨折的疗效分析

目的 比较DHS和PFNA治疗老年骨质疏松性股骨转子间骨折的疗效.方法 61例老年骨质疏松性股骨转子间骨折的患者,31例应用DHS治疗股骨转子间骨折,30例应用PFNA治疗股骨转子间骨折,并对结果进行分析对比.结果 经9～18个月随访,平均12.9个月.PFNA组较DHS组在手术时间、切口长度等方面均有优势;按照Harris髋关节评分标准术后PFNA组和DHS组相比较无明显差异;术后并发症对比PFNA组较DHS组少,而PFNA组易于发生术中股骨干骨折.结论 PFNA治疗老年骨质疏松性股骨转子间骨折具有创伤小、固定牢靠、抗旋转、抗切割等优点,是理想的内固定物.

Analysis of the treatment of osteoporotic femoral intertrochanteric fracture in senile with dynamic hip screw and proximal femoral nail antirotation

Objective To discuss the clinical effects of dynamic hip screw and proximal femoral nail antirotation for osteoporotic femoral intertrochanteric fracture in senile. Methods In this study, 61 cases of osteoporotic proximal femoral fractures in senile were observed. 31 patients were treated with DHS. 30 patients were treated with PFNA.Then, the results were analyzed. Results 61 patients were followed up for 9～18 months(averaged 12.9 months). PFNA group had better effect than DHS group on many aspects such as operation time, incised length. According to Harris criterion,the results of two groups had no significant difference. PFNA group had less postoperative complications than DHS group. More femoral fractures were observed in the PFNA group. Conclusion PFNA has the advantages of less surgical trauma, stable fixation, antirotation and anticutout. So it is an ideal device in the treatment of osteoporotic femoral intertrochanteric fracture.
