Abstract:Abstract:[Objective] We used a meta-analysis to evaluate the clinical efficacy of anterior plating and superior plating in the treatment of clavicle fracture systematically.[Methods] The Pubmed, Embase, Cochrane Library, Web of Science, Chinese biomedical literature service system, China National Knowledge Infrastructure,and Wanfang database were searched for all studies of anterior plating and superior plating in the treatment of clavicle fracture. Quality evaluation of the included literature was assessed using the Cochrane Risk Assessment Tool of and the Newcastle-Ottawa Scale (NOS). Revman 5.30 was used for meta-analysis to compare the differences of operation time, intraoperative blood loss, fracture healing time, incidence of postoperative complications and Constant-Murley Scale(CMS) .[Results] A total of eighteen articles were included, including 1576 patients(with 749 in the anterior-plating group and 828 in the superior-plating group).Compared with the superior-plating group, the anterior-plating group was associated with a lower operation time (MD=-7.25, 95%CI -13.40 ~ -1.10,P <0.05), intraoperative blood loss (MD=-13.31, 95% CI -19.72~ -6.91, P < 0.05), fracture healing time (MD=-9.98, 95% CI -15.16 ~ -4.79, P <0.05), and incidence of postoperative complications (OR=0.25, 95% CI 0.17~0.35, P < 0.05).There was no significant difference in CMS between the two groups(P>0.05).[Conclusions] Compared with the superior plating , the anterior plating can reduce the operation time, intraoperative blood loss, fracture healing time, and the incidence of postoperative complications, but the CMS is similar.
