改良双Endobutton技术治疗肩锁关节脱位和锁骨远端不稳定性骨折的肩关节功能评定

Shoulder function evaluation in acromioclavicular dislocation and unstable distal clavicle fracture treated with modified double endobutton technique

目的对经典的双Endobutton技术进行改良，治疗锁骨远端不稳定性骨折和Rock—woodⅢ型以上的肩锁关节脱位，探索新术式的疗效。方法2010年3月至2011年1月就诊的18例锁骨远端不稳定性骨折和Ⅲ型以上的肩锁关节脱位的患者，予以改良的双Endobutton技术重建喙锁韧带，术后予以Constant—Murley评分。结果术后随访4～10个月，本组14例疗效为优，4例为良，优良率为100％。未发生并发症。结论改良的双Endobutton技术重构锁骨远端的生物稳定性，术式简单易行，手术时间短，疗效满意。

Objective To examine the efficacy of modified endobutton technology in treatment of Tossy type Ⅲ acromioclavicular joint dislocation and unstable distal clavicle fracture. Methods From March 2010 to January 2011,18 patients with Tossy type Ⅲ acromioclavicular joint dislocation and unstable distal clavicle fractures received reconstruction of coracoclavicnlar ligament with modified double endobutton technology. The patients were evaluated after operation according to Constant - Murley score. Results The patients undergoing the operation were followed up for 4 - 10 months. Result of all cases was rated as excellent （14 cases） or good （4 cases） without complication. Conclusion Modified double endobutton technology is an easy and effective method for treating type Ⅲ acromioclavicular joint dislocation and unsta- ble distal clavicle fracture. Function recovery of acromioclavicular joint is fast without complication.
