目的 探讨PFNA治疗股骨转子间伴或不伴外侧壁骨折的临床疗效。方法 选取2011年8月-2014年8月于我院采取PFNA治疗股骨转子间患者98例。按照术前CT三维重建图像观察，分为A组（伴外侧壁骨折组）49例，B组（不伴外侧壁骨折组）49例，对比两组患者的临床疗效。结果 手术后，外侧壁未骨折组的手术时间、住院天数明显小于外侧壁骨折组，且外侧壁未骨折组的术中出血量明显小于外侧壁骨折组，外侧壁骨折组的部分、完全负重时间、骨折愈合时间明显高于外侧壁骨折组，(P<0.05)。结论 对于股骨转子间同时伴外侧壁骨折的患者应当结合CT三维重建技术，具有较高的临床推广和应用价值。

Objective:To study the clinical effect of PFNA in patients of femoral intertrochanteric fracture with or without lateral wall fracture. Method:98 femoral intertrochanteric fracture patients of receiving PFNA from August 2011 to August 2014 in our hospital were selected. According to the preoperative observation of CT three-dimensional reconstruction imaging, the patients were divided into Group A and Group B, 49 cases each group. Group A had lateral wall fracture while Group B did not have lateral wall fracture. The clinical efficacy for two groups was compared. Result:After treatment, the operation time and hospitalization time for Group B was significantly shorter than that of Group A; during operation, the bleeding amount of Group B was fewer than that of Group A; the partial and complete weight bearing time and healing time for Group B was better than that of Group A(P＜0.05).Conclusion: For patients of femoral intertrochanteric fracture complicated with lateral wall fracture, CT three-dimensional reconstruction technology has a higher clinical promotion and application value.
