Arthroscopic-assisted Acromioclavicular and Coracoclavicular Ligaments Reconstruction for Chronic Acromioclavicular Dislocations: Surgical Technique

, : Arthroscopic-assisted Acromioclavicular and Coracoclavicular Ligaments Reconstruction for Chronic Acromioclavicular Dislocations: Surgical Technique. Techniques in Hand & Upper Extremity Surgery 20(4): 172-178

NlmCategory="UNASSIGNED">Chronic acromioclavicular (AC) instability is a rare posttraumatic shoulder condition that can lead to undesirable symptoms like persistent pain, muscle fatigue, loss of strength, or even scapular dyskinesis. It is well known that in these cases the superior functional results depend on the restoration of the anatomy and stability of the AC joint in both vertical and horizontal planes. Considering the ligaments degeneration and atrophy in chronic AC joint dislocations, we present an arthroscopic-assisted reconstruction of both the coracoclavicular and AC ligaments using autograft augmentation. In details the coracoclavicular ligaments component is reconstructed using the Tightrope suspension device augmented with a palmaris longus autograft and by the nonanatomic coracoacromial ligament transfer (modified Weaver-Dunn). The AC part is restored by suturing the remainder palmaris longus autograft on the acromion and on the deltotrapezial fascia. Using the construct provided by this technique all the possible ruptured ligaments are reconstructed, optimizing the vertical and horizontal stability of the area, and promising excellent long-term radiologic and functional results.
