PFNA治疗老年性股骨粗隆骨折疗效观察

Effect observation of PFNA in treating senile femoral intertrochanteric fracture

目的：综合观察PFNA（股骨近端髓内钉系统）治疗老年性股骨粗隆骨折疗效，为治疗老年性股骨粗隆骨折患者提供科学的参考数据。方法：选取在我院2012年3月—2015年3月收治的老年性股骨粗隆骨折患者临床资料72例作为研究对象，随机分为实验组与对照组，每组36例。实验组应用PFNA治疗方法，对照组应用DHS（髋螺钉）治疗方法。结果：实验组平均手术时间为（84.9±13.8）min、平均住院时间为（20.4±3.5）d、平均术中出血量为（200.5±7.8）mL、平均骨性愈合时间为（11.3±1.5）周、并发症发生率为2.8%（1/36）；对照组平均手术时间为（93.3±12.9）min、平均住院时间为（27.5±2.2）d、平均术中出血量为（284.3±15.5）mL、平均骨性愈合时间为（13.4±1.9）周、并发症发生率为8.3%（3/36）；实验组平均手术时间、平均住院时间、平均术中出血量、平均骨性愈合时间以及并发症发生率远远短于对照组（P＜0.05）；两组患者均经过6～12个月的随访，实验组优良率为94.44%（34/36），对照组优良率为80.56%（29/36），实验组优良率远远高于对照组（P＜0.05）。结论：PFNA治疗老年性股骨粗隆骨折疗效较为理想，显著提高术后优良率。

Objective: To observe the therapeutic effect of PFNA (Proximal femoral nail system) in treating senile femoral intertrochanteric fracture and to provide scientific references for the treatment of senile femoral intertrochanteric fracture. Methods: 72 senile femoral intertrochanteric fracture patients treated in our hospital from March 2012 to March 2015 were selected as research subjects and randomly divided into the experiment group and the control group, with 36 cases in each group. The experiment group received PFNA treatment while the control group received DHS (dynamic hip screw) treatment. Results: For the experiment group, the mean operative time was (84.9±13.8) min, the average stay was (20.4±3.5) d, the mean intraoperative blood loss was (200.5±7.8) mL, the average bone union time was (11.3±1.5) week, the complication rate was 2.8% (1/36); for the control group, the mean operative time was (93.3±12.9) min, the average stay was (27.5±2.2) d, the mean intraoperative blood loss was (284.3±15.5) mL, the average bone union time was (13.4±1.9) week, the complication rate was 8.3% (3/36); the the mean operative time, the average stay, the mean intraoperative blood loss, the average bone union time and the complication rate of the the experiment group was significantly shorter than that of the control group (P<0.05); both groups were given a follow-up of 6～12 months, the excellent rate of the experiment group was 94.44% (34/36), which was significantly better than that of the control group 80.56%(29/36), (P<0.05). Conclusion: PFNA had ideal effect in treating senile femoral intertrochanteric fracture and it could improve postoperative excellent rate significantly.
