〔Abstract〕 Objective To investigate the effect of joint capsulotomy on neck femoral fracture healing. Methods A total of 96 patients with femoral neck fracture treated in Xinlicheng Angang General Hospital from May 2016 to May 2020 were enrolled. The patients were divided into an observation group and a control group by random number table method. The observation group underwent joint capsulotomy, and the control group did not undergo joint capsulotomy. The perioperative indicators, fracture healing time, hip joint function recovery, femoral head necrosis rate and incidence of complications were compared between the two groups. Results The operation time and intraoperative blood loss of the observation group were significantly more than those of the control group, and the differences were statistically significant (P < 0.05). There was no significant difference in the time of get out of bed activity and hospitalization time between the two groups (P > 0.05). The fracture healing time of the observation group was (5.08 ± 0.85) months, significantly shorter than (5.89 ± 0.91) months of the control group, and the femoral head necrosis rate of the observation group was 4.17 %, significantly lower than 25.00 % of the control group, the differences were statistically significant (P < 0.05). The Harris scores of the two groups increased significantly with time, and the Harris scores of the observation group at 1, 6 and 12 months after operation were higher than those of the control group, and the differences were statistically significant (P < 0.05). The total incidence of incision infection, deep vein thrombosis, pressure ulcer and other complications in the observation group was significantly lower than that in the control group, and the difference was statistically significant (P < 0.05). Conclusion Joint capsulotomy for patients with femoral neck fracture can promote healing efficiency and reduce the incidence of femoral head necrosis.
