Radiographs of the shoulders of 84 asymptomatic individuals aged between 40 and 83 years were evaluated to determine changes in 23 specific areas. Two fellowship-trained orthopaedic radiologists graded each area on a scale of 0 to II (normal 0, mild changes I, advanced changes II). Logistic regression analysis indicated age to be a significant predictor of change (p < 0.05) for sclerosis of the...

Acromioclavicular (AC) and sternoclavicular (SC) septic arthritis with contiguous pyomyositis are rare, especially in immunocompetent individuals. We report a case of septic AC joint with pyomyositis of the deltoid and supraspinatus muscles and a separate case with septic SC joint with pyomysitis of the sternocleidomastoid muscle. Both patients had similar presentations of infections with Staph...

Acromioclavicular (AC) joint instability is a common source of pain and disability. The injury is most commonly a result of a direct impact to the AC joint. The AC joint is surrounded by a capsule and has an intra-articular synovium and an articular cartilage interface. An articular disc is usually present in the joint, but this varies in size and shape. The AC joint capsule is quite thin, but ...

Dislocation is the most common injury affecting the acromioclavicular (AC) joint. Six grades of AC joint dislocation are currently described, based on the degree and direction, of displacement. Complete rupture of both the AC and coracoclavicular (CC) ligaments is considered to be necessary before complete grade 3 dislocation of the AC joint can occur. Diagnosis is made on the basis of the clin...

OBJECTIVE Shoulder complaints are frequently encountered in general practice, but precise diagnosing is challenging. This study investigated agreement of shoulder complaints diagnoses between clinicians in a primary health care setting. DESIGN Cross-sectional study. SETTING Four primary health care clinicians used patients' history and functional examination of the shoulder by selective tis...

The aim of this study was to establish a classification system for the acromioclavicular joint using cadaveric dissection and radiological analyses of both reformatted computed tomographic scans and conventional radiographs centred on the joint. This classification should be useful for planning arthroscopic procedures or introducing a needle and in prospective studies of biomechanical stresses ...
