股骨颈动力交叉钉系统与空心螺钉治疗股骨颈骨折的疗效对比OA

Objective To compare and analyze the clinical efficacy of femoral neck dynamic cross nail system(FNS)and traditional three cannulated screws in the treatment of femoral neck fracture.Methods A total of 50 patients with femoral neck fracture admitted to our hospital from April 2020 to August 2021 were selected and divided into group A(treated with FNS)and group B(treated with traditional three hollow screws)according to different treatment methods,with 25 cases in each group.The operation time,garden a-lignment index reduction,intraoperative fluoroscopy times,femoral neck shortening,femoral head necrosis,healing time and postoperative Harris score were recorded and compared between the two groups.The patients in the two groups were followed up for more than 12 months.The patients in group A were followed up for(22.1±6.5)months,and the patients in group B were followed up for(23.5±5.3)months.Results The inci-sions of the two groups healed by first intention.The intraoperative fluoroscopy times,Harris score at 12 months after operation and femoral neck shortening in group A were significantly better than those in group B,and the differences were statistically significant(P<0.05).Most of the femoral neck fractures in the two groups healed well,and there was no significant difference in healing time between the two groups(P>0.05).Conclusion Both FNS and hollow screw are effective methods for the treatment of femoral neck fracture.Compared with hollow screw fixation,FNS fix-ation can effectively reduce the incidence of femoral neck shortening.
