Abstract：BACKGROUND:Internal fixations have achieved good outcomes in treatment of intertrochanteric fracture among the elderly. The commonly used internal fixation methods include extramedul ary fixation (dynamic screws) and intramedul ary fixation (proximal femoral nail). Although dynamic screws have been widely applied due to low cost and easy operations, the failure rate of internal fixation is relatively high. Intramedul ary fixation can make up for the shortcomings of extramedul ary fixation. <br> OBJECTIVE:To evaluate the feasibility of proximal femoral nail antirotation with smal incision in treatment of intertrochanteric fracture in the elder patients, and to compare with dynamic screws. <br> METHODS:From August 2012 to June 2013, 40 elderly patients with unstable intertrochanteric fractures were included in this study and were randomly divided into two groups:experimental group and control group. Patients in the experimental group were given proximal femoral nail antirotation with smal incision, while patients in the control group were treated with dynamic screws internal fixation. Postoperative index and Harris score of hip functions in the two groups were compared. <br> RESULTS AND CONCLUSION:There was no differences in the Harris score of hip functions between the two groups (P>0.05), while the experimental group showed shorter operation time and hospital stay, less blood loss and complications then the control group (P<0.05). Compared with dynamic screws internal fixation, proximal femoral nail antirotation therapy with smal incision shows good repairing effects, with fewer complications, smal trauma and high healing rate, it is suitable for the treatment of intertrochanteric fractures among the elderly patients.
