Abstract: Objective To explore the short-term and long-term value of hemiarthroplasty and internal fixation in elderly patients with Garden Ⅰ ~ Ⅱ femoral neck fracture. Methods The general data of 102 elderly patients with femoral neck fracture diagnosed and treated by Haikou People’s Hospital from January 2019 to June 2020 were analyzed retrospectively.They were divided into control group (51 cases) and observation group (51 cases) according to different surgical treatment methods.The control group was treated with hemiarthroplasty,and the observation group was treated with internal fixation.The operation related indexes,hip joint function,muscle injury around the hip,bone metabolic indicators and occurrence of complications. Results The operation time and hospitalization time in the observation group were significantly shorter than those in the control group ,and the intraoperative blood loss  was significantly less than those in the control group.The score of Harris Hip Rating Scale (HHS)  in the observation group was significantly lower than that in the control group  3 and 6 months after operation;The HHS scores  of the two groups had no significant difference 1 and 2 years after operation.Three days after operation,creatine kinase (CK),C-reactive protein (CRP),interleukin-6 (IL-6)  in the observation group were significantly lower than those in the control group at the same time (P＜0.05).Three months after operation,serum osteocalcin (BGP),bone alkaline phosphatase (ALP) and bone morphogenetic protein 2 (BMP-2)  in the observation group were significantly lower than those in the control group（P＜0.05）.One year after operation,there was no significant difference between the two groups in BGP,ALP,BMP-2 .There was no significant difference between the two groups in the incidence of postoperative complications (9.80% vs 15.69%) （P＞0.05）.Conclusion The long-term effect of internal fixation for elderly Garden Ⅰ~Ⅱ femoral neck fracture patients is equivalent to that of hemiarthroplasty,and the former has more advantages in terms of operation time,trauma,etc.
