Abstract: Objective   To explore the clinical value of customized traction table in hemiarthroplasty through the direct anterior approach (DAA) for the treatment of femur neck fractures in elderly patients. Methods  A retrospective analysis of 75 elderly patients with femur neck fractures treated with hemiarthroplasty through DAA were involved in our hospital from September 2018 to December 2019. According to with or without using the traction table, the patients were divided into two groups: Group A (39 cases, DAA hemiarthroplasty with assistance of traction table) and Group B (36 cases, DAA hemiarthroplasty without traction table). There was no significant difference in gender, age, Garden classification, fracture side and other general date between the two groups (P>0.05). The operation indexes, efficacy, postoperative Harris hip score and complications were compared between the two groups.   Results    Group A had longer preoperative preparation time and less operation time than Group B (P<0.05). There was no significant difference in  anesthesia time, intraoperative blood loss and incision length between groups A and B (P>0.05). The central fixation ratio of femoral prosthesis in Group A was higher than that of Group B (P<0.05). The ratio of limb length discrepancy shortened than 10mm, time of first postoperative standing, time of first postoperative walking with crutch, time of first postoperative walking independently, and the Harris score in 1 month and 1 year after the operation were not significantly different (P>0.05). The complication rate was 12.8% (5/39) in Group A and 19.4% (7/36) in Group B (P>0.05). In Group A, lateral femoral cutaneous nerve injury was found in 2 patients, greater trochanteric fracture in 2, and incisional drainage in 1. In Group B, there were 3 patients with lateral femoral cutaneous nerve injury, 2 with greater trochanteric fracture, and 2 with incisional drainages.    Conclusions    For the treatment of femur neck fractures in elderly, hemiarthroplasty via DAA with assistance of customized traction table has remarkable effectiveness. It can significantly shorten the operation time and improve the central fixation ratio of femoral prosthesis, but it also can prolong the preoperative preparation time.
