Objective To investigate the clinical efficacy of retrograde needle insertion reduction technique at the broken end of fracture in the treatment of midshaft clavicle comminuted fracture.Methods Totally 46 patients with midshaft clavicle comminuted fracture in our hospital from January 2018 to October 2021 were selected.They were assigned into routine group(n=23)and needle insertion group(n=23).The patients in routine group underwent routine reduction technique,and patients in needle group was treated with retrograde needle insertion reduction technique at the broken end of fracture.The length of operation,intraoperative bleeding,total incision length and complications of the two groups were recorded and compared.The shoulder pain was evaluated by visual analogue scale(VAS)at 1 day,1 month and 3 months after operation.The shoulder function was evaluated by Constant-Murley score(CMS)for shoulder function at 1,3 and 12 months after operation.Results The length of operation,intraoperative bleeding and surgical incision in needle insertion group were significantly decreased than those of routine group(P<0.05).The complications of fracture nonunion,poor wound healing and brachial plexus injury in the routine group were significantly increased than those of needle insertion group(P<0.05).The 13-15 month follow-up was performed.The CMS scores at 1,3 and 12 months after operation in needle insertion group were significantly higher than those of the routine group(P<0.05),but the VAS scores at 1 day,1 month and 3 months after operation in needle insertion group were significantly lower than those of the routine group(P<0.05).Conclusion Compared with the routine reduction technique,the retrograde needle insertion reduction technique at the broken end of fracture in the treatment of midshaft clavicle comminuted fracture has shorter length of operation,less surgical trauma,fewer complications and better postoperative functional recovery.
