Objective To investigate the value of measurement from the center of femoral head to apex of greater trochanter in patients with femoral neck fracture(FNF)after total hip arthroplasty(THA).Methods A total of 300 patients with FNF were selected from Zhoukou Orthopaedic Hospital from January 2020 to December 2022,and they were randomly divided into conventional control group and research group,150 cases in each group.In the conventional control group,the length of both lower limbs was balanced by bilateral patella leveling.In the research group,the length of the lower limbs was balanced by the measurement from the center of the femoral head to the apex of the greater trochanter.Perioperative indexes,relative length difference of lower limbs,incidence of leg length discrepancy(LLD),incidence of complications,postoperative rehabilitation(fracture healing X-ray score,weight bearing of affected limb),hip function(Harris score),and ability of daily living(improved BI index)were compared between the two groups.Results There were no differences in the intraoperative blood loss,operation time and hospital stay between the research group and conventional control group(P＞0.05).After 6 months of surgery,the relative length difference of lower limbs and the incidence of LLD in the research group were lower than those in the conventional control group(P＜0.05).After 6 months of surgery,the hip Harris scores and the improved BI index in the research group were higher than those in conventional control group(P＜0.05).There was no significant difference in the incidence of postoperative complications between the research group and conventional control group(P＞0.05).Conclusion Using the measurement method from femoral head center to apex of greater trochanter to balance the length of both lower limbs during THA can reduce the incidence of postoperative LLD,effectively improve the hip function of patients after surgery,improve the ability of daily living after surgery.
