Objective To investigate the efficacy of percutaneous cannulated screw combined with improved sliding compression dynamic hip screw internal fixation for treatment of femoral neck fractures.Methods The 35 patients with femoral neck fractures were divided into the conventional group(The 22 cases were treated with percutaneous cannulated screw internal fixation)and the improved group(The 13 cases were treated with percutaneous cannulated screw combined with improved sliding compression dynamic hip screw internal fixation)based on different internal fixation methods.The following data were compared between two groups,including the surgical time,postoperative loading on ground time,hospitalization time,fracture healing time and occurrence of complications between the two groups.Hip joint function was evaluated with using Harris score.Results All patients were followed up for 6～36(19.57±9.45)months.There were no statistical differences between the two groups in surgical time and hospitaliza-tion time(P＞0.05);the postoperative loading on ground time and fracture healing time in the improved group were shorter than those in the conventional group(P＜0.05).There were no cases of nonunion or femoral head necrosis in both groups;the femoral neck shortening rate in the improved group was lower than that in the conventional group(P＜0.05).At the last follow-up,the excellent-good rate of Harris score in the improved group was higher than the conventional group(P＜0.05).Conclusions The improved sliding compression dynamic hip screw is in line with the anatomical and biomechanical characteristics of the femoral neck,which combined with percutaneous cannulated screws internal fixation for treatment of femoral neck fractures have the advantages of early posteroperaive time of load-ing on the ground,short fracture healing time,low femoral neck shortening rate,and good hip joint function recovery for patients.
