Arthrotomography of the unstable shoulder.

Thirty-seven patients suffering from clinically verified subluxation of the shoulder joint underwent double-contrast arthrotomography. Sixteen of these patients were operated on, 4 of whom after arthroscopy, and 1 patient had only arthroscopy. Arthrotomography readily revealed lesions of the glenoid labrum, most of them small, and also redundancy of the anterior joint capsule. The method can be recommended in the examination of the glenoid labrum in patients suffering from anterior subluxation of the shoulder.
