Treatment of Intertrochanteric Fracture: Comparison of Proximal Femoral Nail and Proximal Femoral Nail A

ABSTRACT

PURPOSE: To evaluate the results of fracture fixation between using Proximal Femoral Nail and using Proximal Femoral Nail A and to analyze the effectiveness of proximal femoral nail A. MATERIALS AND METHODS: We reviewed 32 patients who suffered from intertrochanteric fracture in our hospital, which were 19 cases of PFN and 13 cases of PFNA. Retrospectively we evaluated mean operation time, amount of bleeding, beginning of ambulation, average union period, changes of neck shaft angle and complication on set of telephone interview and OPD. We also evaluated postoperative capability of function and mobility using 'Social function score' and 'Mobility score'. RESULTS: PFNA showed shorter mean operation time, less bleeding, shorter average union period, earlier ambulation and less change of neck shaft angle than PFN. Although they didn't show statistical difference, postoperative capability of function and mobility showed statistical and mathematical difference on each group. CONCLUSION: PFNA showed better results of postoperative function and mobility and less complications than PFN. So treatment using PFNA is better method than that of PFN.
