Accurate positioning way to modify minimally invasive incision in the treatment of intertrochanteric fractures with proximal femoral nail antirotation / 中国组织工程研究

ABSTRACT

BACKGROUND:Closed reduction using proximal femoral nail antirotation gradual y becomes the golden standard in the treatment of intertrochanteric fractures. OBJECTIVE:To evaluate the advantages of proximal femoral nail antirotation in the treatment of intertrochanteric fractures by a new way that accurate positioning is used to modify the skin incision. METHODS:Ninety-nine patients with intertrochanteric fractures undergoing proximal femoral nail antirotation were included in the study, including 41 cases in the modified incision group and 58 cases in the standard operation group. Length of skin incision, mean bleeding volume, mean operation time, mean hospitalization time and the Harris scores were compared between two groups postoperatively. RESULTS AND CONCLUSION:Compared with the standard incision group, the mean bleeding volume and length of skin incision were decreased by 50.9%and 44%respectively in the modified incision group, as wel as the mean operation time was also shorter in the modified incision group (P<0.05). However, there was no difference in mean hospitalization time and Harris scores at the end of fol ow-up. The modified incision is more suitable for proximal femoral nail antirotation treatment of intertrochanteric fractures, with smal er incision, less trauma, shorter operation time and less blood loss.
