Instability in distal clavicle fractures with impaired integrity of the coracoclavicular (CC) ligament poses a serious risk of nonunion, necessitating surgical intervention. Despite a consensus on the need for surgery in cases of unstable distal clavicle fractures, various surgical techniques are available. The aim of this study is to evaluate the radiological and functional outcomes of CC augmentation using the suture Endobutton technique for Neer type 2b clavicle fractures were evaluated.
In this retrospective study, 42 patients who met the criteria were divided into two groups: group 1 (locking plate with CC augmentation) and group 2 (locking plate without CC augmentation). Demographic data, Constant-Murley score (CMS), union time, range of motion, complications, and implant failures during the follow-up period were recorded.
Among study patients, 13 (31.0%) were female and 29 (69.0%) were male. The mean age was 40.5±11.5 years. Significant differences were found in union time (week) (t(40)=-2.11, P=0.04) and the 6-month CMS (t(40)=4.19, P=0.01). Significant difference was not observed in postoperative complications between the groups (P>0.05).
CC augmentation with a suture Endobutton in type 2b distal clavicle fractures resulted in more favorable short-term functional and radiological outcomes. Level of evidence: III.
喙锁韧带完整性受损的锁骨远端骨折不稳定会带来骨不连的严重风险，因此需要手术干预。尽管对于不稳定的锁骨远端骨折需要手术已达成共识，但仍有多种手术技术可供选择。本研究的目的是评估使用缝线纽扣钢板技术进行喙锁韧带增强术治疗Neer 2b型锁骨骨折的放射学和功能结果。
在这项回顾性研究中，42例符合标准的患者被分为两组：第1组（带喙锁韧带增强的锁定钢板）和第2组（不带喙锁韧带增强的锁定钢板）。记录人口统计学数据、Constant-Murley评分（CMS）、愈合时间、活动范围、并发症以及随访期间的植入物失败情况。
在研究患者中，女性13例（31.0%），男性29例（69.0%）。平均年龄为40.5±11.5岁。在愈合时间（周）（t(40)=-2.11，P=0.04）和6个月时的CMS（t(40)=4.19，P=0.01）方面发现有显著差异。两组之间术后并发症未观察到显著差异（P>0.05）。
对于2b型锁骨远端骨折，使用缝线纽扣钢板进行喙锁韧带增强术可带来更有利的短期功能和放射学结果。证据等级：III级。
