目的比较3种内固定物,股骨近端防旋髓内钉(PFNA)、动力髋螺钉(DHS)、股骨近端锁定加压钢板(LCP)在治疗老年股骨粗隆间骨折的效果评价。方法纳入研究对象的122例老年骨折患者中,采用PFNA固定的有43例,采用DHS固定的有32例,采用LCP固定的有47例,通过临床记录及随访统计手术操作时间、术中出血量、术后并发症发生率以及术后髋关节功能恢复情况。结果PFNA手术组在骨折愈合时间及髋关节功能评分上与后两组(DHS、LCP)比较差异无统计学意义,但手术操作时间、术中出血量比较差异有统计学意义。122例患者均无相关并发症。结论PFNA设计合理,固定牢固可靠,是治疗股骨粗隆间骨折的理想内固定器材,其微创操作、出血少的优点,更适合老年骨质疏松患者的骨折治疗。

Objective To investigate the therapeutic effect of proximal femoral nail anti-rotation(PFNA)、dynamic hip screw(DHS)and locking compression plate(LCP)for treatment of intertrochanteric fracturein the elderly patients. Methods 122 patients included in the study with intertrochanteric fracture weretreated with fracture fixation operation,43 cases with PFNA fixation,32 cases with DHS fixation and 47 cases with LCP fixation. The operation time,intraoperative bleeding and postoperative complications,postoperative hip joint function were recorded through follow-up and clinical records statistics. Results PFNA group had less operative time and intraoperative blood loss compared with the other two groups(DHS、LCP),There were no significant differences on the healing time and hip function score in thosegroups. There were no complications in all the 122 patients. Conclusion PFNA has the characteristicsof reasonable design and reliable fixation strength. It is the appropriate method of the treatment for femoralof intertrochanteric fracture,especially to those elderly with unstable osteoporosis intertrochantericfractures for its advantages of less bleeding and minimally invasiveness.
