Abstract: Objective  To observe the clinical effect of shoulder abduction brace combined with trigen interlocking intramedullary nail in the treatment of proximal humeral fractures.  Methods  55 patients with proximal humeral fractures treated in our hospital from January 2020 to January 2021 were divided into two groups according to different treatment schemes.The control group:26 patients were treated with trigen interlocking intramedullary nail.Study Group:29 cases were treated with shoulder abduction brace combined with trigen interlocking intramedullary nail.The results of reduction evaluation,clinical healing time of fracture,bone healing time of fracture,constant Murley shoulder function score and shoulder range of motion were compared.  Results  The reduction assessment of the study group were significantly better than those of the control group.The clinical healing time of fracture in the study group was shorter than that in the control group,and the bone healing time of fracture was shorter than that in the control group(P＜0.05).One year after operation,the constant Murley shoulder function score of the control group and the study group were were higher than 1 month after surgery(P＜0.05).One year after operation,the constant Murley shoulder function score of the study group was not significantly different from that of the control group(P＞0.05).Following up for 1 year,there was no significant difference between the two groups in the activities of flexion and lifting,external rotation and abduction(P＞0.05).  Conclusion  The shoulder abduction brace combined with trigen interlocking intramedullary nail is conducive to the reduction of proximal humeral fractures,shorten the clinical healing time and bone healing time of fractures,and it is conducive to improving the early shoulder joint function and range of motion.
