Comparison of the efficacy of small-incision clamp-assisted reduction and open reduction for the treatment of femoral shaft fractures with an anterograde intramedullary nail: a retrospective study

Abstract

Background To compare the efficacy of small-incision clamp-assisted reduction with open reduction for the treatment of femoral shaft fractures by anterograde intramedullary nailing. Methods The data of 63 patients with femoral shaft fractures, treated between January 2016 and June 2021, were retrospectively analyzed. All patients received anterograde intramedullary nail fixation, and the OA/OTA classification of fractures was 32-C. The average follow-up period was 13 months (range: 11–14 months). According to the method of fracture reduction, patients were divided into a small-incision clamp-reduction group (referred to as the clamp-reduction group) and an open-reduction group. The reduction time, operative time, the number of fluoroscopy, intraoperative blood loss, postoperative VAS score, postoperative time to discharge, and the rates of intraoperative and postoperative complications were compared between the two groups. Results There were statistically significant differences in reduction time, operative time, the number of fluoroscopy, intraoperative blood loss, postoperative VAS score, postoperative time to discharge (t = 6.718, − 11.679, 18.963, − 11.609, − 22.432, − 7.187; P < 0.05). In the clamp-reduction group, there was no intraoperative blood transfusion. However, there were one case of wound infection and one case of deep vein thrombosis after operation. In the open-reduction group, ten patients received intraoperative blood transfusion, one patient developed hemorrhagic shock, two patients developed wound infection, and two patients developed bone nonunion during follow-up. Conclusions Both groups had good functional recovery after operation. However, compared with open reduction, clamp reduction is a safer reduction method with shorter operation time, less intraoperative blood loss, less postoperative pain, shorter hospital stay and fewer postoperative complications.
