[X-ray computed tomography in the study of anterior instability of the shoulder. Study of a series of 23 cases].

The place of standard CT scan imaging more particularly when combined with double contrast arthrography, is defined in the preoperative screening of patients with anterior instability of the shoulder. The joint scan provides complete data on the anatomic elements of the shoulder lesion, particularly with reference to the glenoidal labrum and the anterior capsular structure. It is also of major diagnostic value in painful subluxations.
