Long nail Short nail P Blood loss ml Treatment of pertrochanteric fractures OTA A1 and A2 : long versus short cephalomedullary nailing. Conclusions Both the long and short intramedullary nails are the optional internal fixation choices for femoral intertrochanteric fracture in the aged patients older than 65 years. Several recently studies have found no differences using long or short intramedullary for femoral intertrochanter fractures in the elderly [ 6 - 8 ]. Short versus long cephalomedullary nails for the treatment of intertrochanteric hip fractures in patients older than 65 years. There were no intraoperative complications. In Clinical practice, both a long and short nail could be chosen for less osteoporosis OTA A1 and A2 fractures, while long nail fixation will be used for more severe osteoporosis OTA A1 and A2 fractures or comminuted A3 fractures in order to achieve very satisfactory results. So the overall failure rate in our study is relatively lower that their study. Postoperatively, patients were allowed to bear weight as tolerated.
