[Paraglenoid hyerostosis: shoulder arthrosis or occupational?]

Amongst 300 examinations of the shoulder in miners working with compressed air, degenerative changes were found in 44. Particularly striking was the frequency of acromioclavicular arthrosis and of paraglenoid hyperostosis. Five patients with paraglenoid hyperstosis were re-examined several years later. The authors regard these changes as a sign of shoulder arthrosis, analgous with hyperostosis of the head of the radius or of a rib and with labrum ossification of the hip joint.
