ObjectiveTo systematically evaluate the effect of coracoclavicular ligament reconstruction and clavicular hook plate for the treatment of unstable distal clavicular fracture. MethodsThe databases of PubMed, The Cochrane Library, Embase, China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, VIP, Chinese Biomedical Literature Service System, etc., were retrieved by computer, the literature related to coracoclavicular ligament reconstruction and clavicular hook plate for the treatment of unstable distal clavicular fractures was enrolled. According to the inclusion and exclusion criteria, the eligible literature was screened, after the evaluation of the literature quality, the effective data were extracted. The RevMan 5.4 software was used for Meta-analysis. ResultsA total of 23 literature was enrolled, involving 1119 patients. The results of Meta-analysis revealed that coracoclavicular ligament reconstruction for the treatment of unstable distal clavicular fracture exerted superior aspects of shoulder joint Constant-Murley score, American Shoulder and Elbow Surgeons (ASES) score, postoperative Visual Analogue Scale score for pain, incidence rate of postoperative complications, and wound length to compare with clavicular hook plate therapy, but the former exhibited longer operation duration (P＜0.05). There was no statistically significant difference in intraoperative bleeding volume between the two surgical methods (P＞0.05). ConclusionCoracoclavicular ligament reconstruction for the treatment of unstable distal clavicular fractures is superior to clavicular hook plate in terms of restoring shoulder joint function, relieving postoperative shoulder joint pain, decreasing the incidence rate of postoperative complications, and obtaining wound aesthetics, but the former exhibits longer operation duration, whereas intraoperative bleeding volume is similar between the two surgical methods.
