Effect of open reduction and internal fixation with closed reduction and internal fixation on femoral head necrosis and fracture healing rate

Abstract

Objective To study the effect of open reduction and internal fixation with closed reduction and internal fixation on femoral head necrosis and fracture healing rate. Methods Selected 68 cases of femoral neck fracture as the research objects, the patients were randomly divided into open reduction group and closed reduction group, 34 cases in each group, the functional recovery, fracture healing and necrosis of the femoral head were compared between the two groups. Results The excellent rate of functional recovery of open reduction group was 79.4%, which was slightly lower than that of closed reduction group (88.2%), but the difference was not significant (P>0.05). The nonunion rate of the open reduction group was 20.6%, which was slightly higher than that of the closed reduction group (14.7%), but the difference was not significant (P>0.05). The rate of necrosis of the femoral head in the open reduction group was 29.4%, which was significantly lower than that of the closed reduction group (P<0.05). Conclusions Open reduction and internal fixation with closed reduction and internal fixation in the treatment of femoral neck fracture, with a higher reduction quality, can reduce the incidence of femoral head necrosis, it is worthy of clinical application and promotion.
