Objective To compare two different techniques of proximal pin placement for the treatment of intertrochanteric fractures in elderly patients utilizing the orthofix pertrochanteric fixator. Methods From January 2015 to December 2018, 70 elderly patients with intertrochanteric fracture caused by lowenergy trauma who received surgical treatment in our hospital were selected as the research objects. According to the placement method of proximal screw, they were divided into group A (proximal screw is convergent insertion type) and group B (proximal screw is horizontal insertion type), with 35 cases in each group.Results The mean radiographic exposure during pin insertion in Group A and Group B was 15 and 6 seconds, respectively（P＜0.05）. At 180 days after surgery, the excellent rate of Harris Hip Score in group A and group B were 94.28% and 91.42% （P＞0.05）. There was no significant difference in the incidence of postoperative complications between the two groups (P＞0.05). Conclusion Compared with the convergent placement, the parallel placement of proximal screw is more simple and feasible, which can effectively reduce radiation exposure. In addition, the way of parallel or convergent insertion of the proximal screw had no significant effect on the final surgical outcome.
