Abstract：Objective To analyze the related surgical indicators of three types of internal fixation surgery for intertrochanteric fractures in elder patients. Methods 93 elder patients of femoral intertrochanteric fractures were selected and divided into PFNA group, DHS group and LISS group according to different treatment methods, with 31 cases in each group, and the operation-related indicators of the three groups were compared. Results In PFNA group, the operation time was shorter than DHS group and longer than LISS group, intraoperative blood loss was less than DHS group and more than LISS group, wound size, postoperative drainage and bed rest time were better than LISS and DHS group. All of differences between groups were statistically significant（both P＜0.05）. Conclusion Proximal femoral anti-rotational intramedullary nailing is preferred for intertrochanteric fractures in elder patients. If the patients with proximal femoral lateral wall fracture or a piriform fossa fracture, an inverted minimally invasive internal fixation system in the distal femur can be selected.
