Evaluation and treatment of acromioclavicular joint injuries. Abstract. Injuries to the acromioclavicular AC joint are common, tending to occur secondary to traumatic injuries. Rockwood grade IV, V and VI injuries involve complete dislocation of the joint and require surgical reconstruction, with inconclusive literature on whether grade III injuries should be surgically or conservatively managed.
A biomechanically-based surgical treatment approach for high grade acromioclavicular AC joint injuries is necessary in order to restore the clavicle’s key role as a mobile strut for scapular and arm motion, the AC joint’s role as the unifying link in the screw axis mechanism that governs normal scapulohumeral rhythm, and the 3-dimensional nature of the normal kinematics of the clavicle. Primary AC joint stability can be restored by AC capsule augmentation, while position of the additional suture construct is critical. It was hypothesized that techniques that reconstruct the anterior capsular structures would restore native stability against rotations and translations. The following techniques were used to reconstruct the AC ligaments: a graft was shuttled underneath the AC joint back from anterior and again sutured to the acromial side of the joint group 1, a graft was fixed intramedullary in the acromion and distal clavicle group 2, a graft was passed over the acromion and into an acromial tunnel group.

However, recurrent dislocation is one of the main complications associated with the majority of these techniques. We report a case of postoperative AC joint redislocation. In order to overcome recurrent dislocation after revision surgery, a reconstruction of the conoid and trapezoid.
