ENTHESOPATHY OF THE CORACOACROMIAL LIGAME NT AND ROTATOR CUFF

Ossification of the coracoacromial ligament was looked for routinely o n the roentgenograms of 50 patients with arthrographically-documented rotator cuff tear and of 25 controls free of clinical evidence of shou lder disease. Ossification of the coracoacromial ligament was seen in none of the 25 controls versus 12 of the 50 patients. The ossification consistently arose from the acromial attachment site. A few patients developed ossification of the entire ligament bridging the gap between the acromion and coracoid process.
