Abstract：Objective To observe the influence of three dimensional memory fixator in repair of posterior wall frac-ture complicated with posterior dislocation of joint on curative effect and hip joint function recovery.Methods 91 cases of patients with posterior wall fracture complicated with posterior dislocation of joint treated in our hospital were se-lected as the study objects.According to different internal fixations,the patients were divided into three-dimensional memory group(45 cases)and reconstructive plate group(46 cases).The three-dimensional memory group underwent three dimensional memory internal fixators repair,and the reconstructive plate group underwent reconstruction plate in-ternal fixation.Clinical indicators,hip function,clinical efficacy were observed in the two groups,and the incidence of complications was calculated.Results Operation time,intraoperative blood loss in three-dimensional memory group were significantly lower than those in the reconstructive plate group(P<0.05).After 1 year treatment,joint deformity, mobility,pain degree and limb function score were significantly higher than those before treatment in the two groups (P<0.05).Those in the three-dimensional memory group were significantly higher than those in the reconstructive plate group(P<0.05).The excellent and good rate of the three-dimensional memory group was 91.30%,slightly high-er than that of 82.22% of the reconstructive plate group(P>0.05).Complication rate of 3D memory group was 4. 35%,slightly lower than that of 13.33% in the reconstructive plate group(P>0.05).Conclusion Three dimensional memory fixator in Repair of posterior wall fracture complicated with posterior dislocation of joint,it can effectively pro-mote the recovery of hip joint function,with less complications and definite clinical effect.
