Abstract:【Abstract】 Objective To explore the curative effect of incision reduction cannulated screw internal fixation with closed reduction and hollow screw fixation in the treatment of displaced femoral neck fractures. Methods 96 femoral neck fracture patients were divided into the incision reduction group (45 cases) and closed reduction group (51 cases), according to the different methods of reduction. All the patients adopted three cannulated screw internal fixation after reset. The general surgery, clinical curative effect and complications were observed. Results The operation time, the intraoperative blood loss, the fracture rate of good quality, Harris hip score of the last followup function and the incidence of femoral head necrosis of incision reduction group were statistically different from that of closed reduction group (P< 005). The intraoperative fluoroscopy time, the nonunion occurrence rate, the incidence of the coxa vara and the incidence of internal fixation slipping of incision reduction group and closed reduction group had no difference (P>005). Conclusion The cannulated screw internal fixation can get ideal fracture effect, reduce the incidence of femoral head necrosis and obtain more ideal forward curative effect.
