The efficacy of total hip arthroplasty after failed internal fixation of displaced femoral neck fractures in the elderly
Objective To investigate the effect of total hip arthroplasty(THA)after failed internal fixation of dis-placed femoral neck fracture in the elderly.Methods THA was used to treat the failed internal fixation after dis-placed femoral neck fracture in 29 elderly patients.The operative conditions and postoperative complications,pain VAS,hip Harris score and SF-36 quality of life score were recorded.Results All patients were followed up for 12～20 months.The operative time was 72～136(99.52±20.22)min,the incision length was 8.2～16.4(13.15±2.27)cm,the intraoperative blood loss was220～516(340.83±83.91)ml,and the postoperative drainage volume was 121～296(193.07±56.12)ml.The duration of hospitalization was 11～21(16.41±3.08)days.Postoperative complications occurred in 6 cases,including 2 cases of lower extremity intermuscular venous thrombosis,1 case of de-lirium,1 case of urinary retention,2 cases of prosthesis posterior dislocation,all of which were cured after symptomatic treatment.At the last follow-up,the pain VAS,Harris score and SF-36 score were significantly improved,compared with those before THA(P＜0.01).Conclusions THA is an effective measure for treatment of the failure internal fix-ation of elderly displaced femoral neck fracture,which can significantly improve hip function and quality of life of pa-tients.However,it is necessary to prevent the dislocation of prosthesis after surgery,which suggests that the surgeon should do a good job in preoperative evaluation and planning,intraoperative careful operation,postoperative standard rehabilitation exercise.
