评估应用缝合锚钉重建喙锁韧带，治疗急性肩锁关节脱位的临床结果。

自2014年2月至2015年6月接受手术治疗的急性肩锁关节脱位患者13例，其中男性8例、女性5例；平均年龄为（40.0±15.6）岁。应用缝合锚钉重建喙锁韧带，复位固定肩锁关节。术后应用三维CT评估喙突上缝合锚钉的位置情况；通过肩关节正位片评估肩锁关节复位保持情况，并测量喙锁间距；记录肩关节的活动范围、视觉模拟评分（visual analogue scale，VAS）和Constant-Merly评分。

所有患者均顺利康复。术后肩关节前屈上举平均为171.5°，体侧外旋为70.8°，体侧内旋为T8。VAS评分为（0.3±0.6）分，Constant-Merly评分为92.4分。术后术侧的喙锁间距平均为（8.9±3.0）mm，健侧的喙锁间距平均为（7.7±1.7）mm，两者之间差异无统计学意义（P=0.119）。26枚锚钉中有23枚位置良好，1枚锚钉刺穿了喙突的下表面，2枚锚钉位置偏向内侧。1例患者肩锁关节复位完全丢失，1例患者肩锁关节复位部分丢失，其Constant-Merly评分分别为74分和84分。

通过在喙突基底部准确地置入缝合锚钉，可以解剖重建喙锁韧带，恢复肩锁关节的垂直和水平稳定性。该技术创伤小，可以取得较为满意的临床结果。

Acromioclavicular joint dislocation accounts for 9%-12% of all injuries of the shoulder. It is generally accepted that patients with grades IV and V injuries benefit from operative treatment. Although the optimal management for grade III injuries remains contentious, many authors agree that surgical treatment seems to be a feasible choice for physically active young adults. Surgical stabilization of the AC joint could prevent disabling pain, weakness, and deformity. Numerous surgical methods have been described for AC joint reconstruction. While nearly every operative method has its advantage, each one is associated with disappointing failure cases. The use of suture anchors for coracoclavicular reconstruction could potentially diminish the risk of neurovascular injury and clavicle or coracoid fracture. Also, there is no need for a secondary operation for implant removal.

To evaluate the outcome of coracoclavicular ligament reconstruction with suture anchors for the treatment of acute acromioclavicular joint dislocation.

The study involved 13 patients with acute acromioclavicular joint dislocation treated surgically from February 2014 to June 2015. There were 8 males and 5 females at average age (40.0±15.6) years. The dislocated acromioclavicular joint was reduced and maintained with suture anchors through coracoclavicular ligament reconstruction. Computed tomography with 3-D reconstruction of the injured shoulder was performed on each patient postoperatively for the assessment of the accuracy of the suture anchor placement in the coracoid process. Radiographs of both shoulders were taken for evaluating the maintenance of the acromioclavicular joint reduction and measuring the coracoclavicular distance at each follow-up visit. The range of motion of the shoulder, VAS score and Constant-Murley score were all recorded at final follow-up.

The average forward flexion of the shoulder was (171.5±9.9) °. The average external rotation was (70.8±7.6) °. The internal rotation was T8. The mean VAS score was (0.3±0.6) . The mean Constant-Murley score was (92.4±7.8) . The mean coracoclavicular distance of the affected side was (8.9±3.0) mm and that of the contralateral shoulder was (7.7±1.7) mm at the final follow up. The difference was not significant (P>0.05) . 23 of the 26 anchors implanted in the coracoid process had good position. There was one anchor inserted too deeply in a wrong angle and penetrated the under surface of the coracoid process. Both of the two anchors in one case were placed too medially. One patient developed complete loss of reduction and another had partial loss of reduction, and the Constant-Murley score were 74 and 84 respectively.

With this minimally invasive approach and limited exposure of the coracoid, a surgeon can precisely place the suture anchors at the anatomical insertions of the coracoclavicular ligament on the coracoid process. Acromioclavicular joint reduction with horizontal and vertical stability is achieved with satisfactory results.
