摘要
Objective:To evaluate the early-term effectiveness of Latarjet procedure with double EndoButtons fixation for recurrent anterior shoulder dislocation by coracoid osteotomy with preserving coracoacromial ligament.
Methods:Between January 2021 and June 2023, 19 patients with recurrent anterior shoulder dislocations were treated by arthroscopic Latarjet procedure with double EndoButtons fixation, all of which underwent coracoid osteotomy with preserving the coracoacromial ligament. There were 11 males and 8 females, with an average age of 23.3 years (range, 17-32 years). Shoulder dislocations ranged from 3 to 11 times, with an average of 6.4 times. The disease duration ranged from 3 to 35 months, with an average of 12.9 months. All apprehension tests were positive. Imaging examination showed that the defect width of the ipsilateral glenoid bone was 13%-26%, with an average of 19.8%. After operation, the shoulder range of motion was examined, including flexion lift, lateral external rotation, extension 90° external rotation, and internal rotation. Shoulder joint function was evaluated by Walch-Duplay score, American Association for Shoulder and Elbow Surgery (ASES) score, and Rowe score. Imaging examinations were taken to observe the position and shaping of coracoid.
Results:All incisions healed by first intention and no nerve or vessel injury occurred. All patients were followed up 9-24 months (mean, 14.5 months). There was no recurrence of shoulder dislocation and the apprehension tests were negative during follow-up. There was no significant difference in the shoulder range of motion (flexion lift, lateral external rotation, extension 90° external rotation, and internal rotation) between preoperation and at last follow-up ( P>0.05). The Walch-Duplay score, ASES score, and Rowe score significantly improved when compared with those before operation ( P<0.05). Postoperative imaging showed that coracoid graft was at the same level with the glenoid in all cases; the center of coracoid graft was located between 3 to 5 o'clock. During follow-up, there was no glenohumeral joint degeneration, the acromiaohumeral distance was not reduced when compared with preoperation, and the coracoid bone gradually formed concentric circles with the humeral head.
Conclusion:The Latarjet procedure with double EndoButtons fixation can effectively treat recurrent anterior shoulder dislocation by coracoid osteotomy with preserving coracoacromial ligament, and the early-term effectiveness is satisfactory.
