Objective To compare the efficacy of different surgical treatments on hip fracture and the influence on hip joint function and bone metabolism index of patients.Methods 108 patients with hip fracture were divided into the internal fixation group and the replacement group according to random number table method,with 54 cases in each group.The internal fixation group was treated with proximal femoral intramedullary nail-spiral blade internal fixation,and the replacement group was treated with artificial joint replacement surgery.Both groups were followed up for 6 months after surgery.The clinical efficacy,proprioceptive balance function related indexes,bone metabolism indexes,hip joint function and complications were compared between two groups.Results At 6 months after operation,the excellent and good rate of the replacement group was higher than that of the internal fixation group(P<0.05).Compared with before operation,at 6 months after surgery,the levels of serum osteocalcin(BGP),parathyroid hormone(PTH)and bone alkaline phosphatase(BALP),and Harris hip score and hip function recovery scale(FRS)score in two groups increased,and the replacement group was higher than the internal fixation group(P<0.05);Scores of Berg balance scale increased in two groups,but Berg balance scale scores in the replacement group were lower than those in the internal fixation group(P<0.05);Bone mineral density in the replacement group increased and was higher than that in the internal fixation group(P<0.05).During follow-up,the total complication rate in the replacement group was lower than that in the internal fixation group(P<0.05).Conclusion Proximal femoral intramedullary nail-spiral blade internal fixation can improve the balance ability of patients with hip fracture.But artificial joint replacement surgery can effectively improve the bone metabolism indexes of patients,promote the recovery of hip joint function,reduce the occurrence of complications,and has relatively better therapeutic effects.
