Objective To compare the efficacy of total hip arthroplasty(THA)for treatment of femoral neck fracture via Hardinge approach and SuperPATH approach.Methods The 100 patients with femoral neck fractures were divid-ed into SuperPATH group(treated with SuperPATH approach THA)and Hardinge group(treated with Hardinge ap-proach THA),according to random number table method,with 50 cases in each group.Operation conditions,acetabu-lar abduction angle and its safe zone ratio,anterior inclination angle and its safe zone ratio,offset and its recovery rate,length difference of both lower limbs and the incidence of complications were recorded in the two groups.Hip function was assessed by Harris score.Results All patients were followed up was 12～16 months.Incision length,intraopera-tive blood loss,start walking time without weight-bearing and length of hospital stay in SuperPATH group were all shorter(less)than those in Hardinge group(P<0.05).The operation time of SuperPATH group was longer than that of Hardinge group(P<0.05).At 6 months after operation,there were no statistical differences in acetabular abduction angle and its safe zone ratio,acetabular anterior inclination angle and its safe zone ratio,offset and its recovery rate,and lower limb length difference between the two groups(P>0.05).The excellent-good rate of Harris score:at 6 months after operation,SuperPATH group was higher than Hardinge group(P>0.05),and two groups had no differ-ence at 12 months postoperation(P<0.05).Conclusions Compared with Hardinge approach,although SuperPATH approach has a certain learning curve for the treatment of femoral neck fracture,it can accurately insert prosthesis,and has the advantages of less trauma,fewer complications,faster recovery,and better short-term efficacy.
