Isolated Acromioclavicular Joint Pathology in the Symptomatic Shoulder on Magnetic Resonance Imaging: A Pictorial EssayGordon, Benjamin H MD*†; Chew, Felix S MD*Journal of Computer Assisted Tomography: March-April 2004 - Volume 28 - Issue 2 - p 215-222 Musculoskeletal Imaging Abstract Author Information The acromioclavicular (AC) joint is a synovial joint that is predisposed to painful syndromes because of mechanical stress or developmental variation. It is often overlooked in the evaluation of patients with shoulder pain, however. Isolated AC joint pathology was studied on magnetic resonance imaging scans of patients with symptoms suggesting rotator cuff pathology. The conditions identified included osteoarthritis, distal clavicle osteolysis, and os acromiale syndrome.
