Abstract:Objective To investigate the application of hollow nail internal fixation combined with quadratus femoris bone flap transplantation in young patients with femoral neck fracture. Methods Totally 96 young patients with femoral neck fracture who were admitted into our hospital from October 2015 to December 2016 were enrolled and randomly divided into observation group in which patients received hollow nail internal fixation combined with quadratus femoris bone flap transplantation (n = 48), and control group in which patients received hollow nail internal fixation (n = 48). Operation related features, hemodynamics, bone metabolism, clinical efficacy and complications were recorded. Results Patients in observation group experienced increased levels of operative time and intraoperative blood loss, and decreased time duration of healing compared with control group (P < 0.05). At the 3rd month after surgery, the whole blood high shear, whole blood low shear, plasma viscosity and erythrocyte specific volume were decreased, while blood concentration of alkaline phosphatase (ALP), osteoprotegerin (OPG) and osteocalcin (BGP) were increased significantly in observation group when compared with those in control group (P < 0.05). At the 6th month after surgery, effective rate was enhanced while incidence of complications such as necrosis of femoral head was decreased in observation group compared with those in control group (95.37% vs 79.17%, 18.75% vs 37.50%, P < 0.05, respectively). Conclusions Hollow nail internal fixation combined with bone flap transplantation of quadratus femoris muscle can promote postoperative rehabilitation of young patients with bone and neck fracture, and reduce the incidence of adverse reactions.(P < 0.05).
