Surgical Reatment of Acromioclavicular Dislocation-reconstruction of Coracoclavicular Ligament

Background: Dislocation of acromioclavicular joint is a relatively common injury, accounting for about 9% to 10% of all shoulder injuries. There are many surgical methods to treat dislocation of acromioclavicular joint, including fixation through acromioclavicular joint, intercoracoid fixation and ligament reconstruction. However, at present, more and more attention has been paid to biological reconstruction technology, and related technologies have also been greatly developed. Methods: The semitendinosus tendon from the body is used as the material for the reconstruction of the ligament. The reconstruction holes were made at the original attachment of the clavicular conical ligament and the trapezium ligament, and 10 absorbable lines were taken to pass through the lower part of the coracoid process through the two reconstruction holes respectively. The semitendinosus tendon was pruned, and the two ends were inserted through the reconstruction holes respectively to reach the lower part of the coracoid process. While pressing down on the clavicle, 10 absorbable lines were knotted on the surface of the clavicle, and the semitendinosus tendon was knotted below the coracoid process. Finally, two u-shaped loops were formed to complete the reconstruction of the coracoid ligaments. Results: The intraoperative and post-operative imaging examination indicated that acromioclavicular joint dislocation was well treated. Conclusions: This kind of surgery has many advantages over traditional plate fixation, such as reducing postoperative complications, shortening the length of hospital stay and so on.
