Abstract: 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.
