Most patients with distal clavicle osteolysis (DCO) present with pain over the distal end of the clavicle and acromioclavicular (AC) joint, which is usually described as a dull ache. Patients with an etiology of trauma report a specific event as the start of their symptoms. In patients with repetitive/overuse injuries, pain is exacerbated by athletic or work activity. In weightlifters, most symptoms occur with the bench press and related exercises. [9]


Physical Examination

On physical examination, patients have point tenderness over the affected AC joint, and cross-chest maneuvers elicit pain. Usually, the AC joint is not unstable; however, crepitation may be present. Range of motion (ROM) of the glenohumeral joint should be full.
