Objective:To investigate the short-term clinical results of femoral neck fractures of the young and middle-aged using FNS(femoral neck system).Methods:divided 53 cases of patients with femoral neck fractures(GardenⅠ-Ⅲ)into the observation group and the control group according to the random number table method,27 cases in control group were treated with CCS,26 cases in observation group with FNS.The operation time,intraoperative blood loss,fluoroscopy frequency,VAS scores,hospitalstay,postoperative complications,full load time,fracture healing and Charnley hip function scores at postoperative 12 months were compared between the two groups.Results:Although there were no singificant differences in operative time,intraoperative blood loss,VAS scores and hospital stay between the two groups(P＞0.05),the Observation group proved singificantly superior to the Control group in terms of intraoperative times of fluoroscopy(P＜0.05).The Observation group resumed full-weight-bearing activity singificantly earlier than the Control group(P＜0.05).The total incidence of postoperative complications in the Observation group were lower than those in the Control group(P＜0.05).At 12 months,the incidence of nonunion and malunion in the Observation group were lower than those in the Control group(P＜0.05),meanwhile the Observation group was significantly superior to the Control group in terms of the Charnley hip function scores(P＜0.05).Conclusion:The FNSfor internal fixation of femeral neck fracture in young and middle-aged takes the advantages of strong fixation stability,good recovery of hip function and fast fracture healing.
