ABSTRACT
Objective To compare the clinical curative effect of proximal femoral nail anti rotation ( PFNA) and dynamic hip screw fixation in the treatment of the femoral intertrochanteric fracture,and provide reference for the development of clinical surgery scheme.Methods 74 patients with femoral intertrochanteric fracture in our hospital were selected and randomly divided into observation group and control group,37 cases in each group.The control group was treated with dynamic hip screw fixation,and the observation group was treated with PFNA therapy.Opera-tive time,bleeding volume and wound healing were compared between the two groups.The time of bone healing and complications were compared between the two groups after operation 1,3,6 months, functional recovery of hip was evaluated after operation by Harris score in the two groups.Results Intraoperative bleeding in the observation group was (115.68 ±72.38)mL,the operation time was (43.26 ±11.47)min,which were significantly less than the con-trol group(t=9.62,7.11,all P0.05).1 month after surgery,the Harris score of the observation group was (71.39 ±4.38)points, which was significantly higher than the control group (t=3.17,P0.05 ) .Conclusion PFNA had less surgical trauma,early functional exercise for patients after surgery by comparison with dynamic screw fixation.It could promote fracture and hip joint function rehabilitation.
