摘要：Objective To evaluate the efficacy of reconstructing the coracoclavicular ligament using Endobutton technique for dislocations of the acromioclavicular joint. Methods From April 2009 to September 2010, 31 cases of acromioclavicular joint dislocation were treated by the Endobutton technique in our department. They were 29 males and 2 females, with a mean age of 41. 7 years old (range, 25 to 66 years). According to the Rockwood classification, there were 4 cases of type IE, 13 of type IV and 14 of type Ⅴ. Twenty-nine patients with acute dislocation underwent surgery after a mean time of 4. 6 days (range, 3 to 7 days) from injury to reconstruction. Two patients with chronic dislocation underwent surgery after a mean time of 4. 5 months (range, 4. 2 to 4. 8 months) after injury. Operation time, visual analog scale (VAS) and Constant shoulder scores, and complications of the patients were documented for analysis. Results All the patients were available for a mean follow-up of 15. 2 months (range, 6 to 23 months) . The mean VAS score of the patients was 5. 9 ± 2. 1 preoperatively, compared with 0. 2 ± 0. 4 at the final follow-up evaluation.The difference was statistically significant (t = 14. 39, P < 0. 05) . The mean Constant score was 35. 7 ± 15. 2 preoperatively, compared to 95. 9 ± 5. 8 at the final follow-up evaluation. The difference was statistically significant (t = 22. 23, P < 0. 05) . Follow-up found loosening of Endobutton plate in one case, shoulder stiffness in another and local skin numbness in 4 cases. Conclusion Endobutton technique to reconstruct the coracoclavicular ligament can achieve good outcomes in treatment of acromioclavicular joint dislocation,such as anatomical reduction, sustainable and stable fixation, consistency with bio-mechanical needs, limited invasion, fewer postoperative complications, and no need of a secondary operation to remove implants.%目的 探讨ENDOBUTTON技术重建喙锁韧带治疗肩锁关节脱位的临床疗效.方法 2009年4月至2010年9月采用ENDOBUTTON技术重建喙锁韧带治疗31例肩锁关节脱位患者,男29例,女2例;年龄25～66岁,平均41.7岁.按Rockwood分型:Ⅲ型4例,Ⅳ型13例,Ⅴ型14例.新鲜骨折脱位患者29例,受伤至手术时间为3～7 d,平均4.6 d;陈旧性肩锁关节脱位患者2例,受伤至手术时间为4.2～4.8个月,平均4.5个月.对视觉模拟评分(VAS)、肩关节Constant评分及并发症等进行随访研究.结果 31例患者术后获6～23个月(平均15.2个月)随访.末次随访时VAS评分为(0.2±0.4)分,与术前(5.9±2.1)分比较差异有统计学意义(t=14.39,P<0.05);Constant评分平均为(95.9±5.8)分,与术前(35.7±15.2)分比较差异有统计学意义(t=22.23,P<0.05).随访发现ENDOBUTTON钢板松动、移位1例,肩关节僵硬1例,局部皮肤麻木4例.结论 ENDOBUTTON技术具有解剖复位、持续稳定的固定、符合生物力学要求、手术创伤小、术后并发症少及无需二次手术取出等优点,应用其治疗重建喙锁韧带治疗肩锁关节脱位可获得满意疗效.
