The Double-Contrast Shoulder Arthrogram

Abstract

Experience with double-contrast arthrography indicates it is superior to the single-contrast technique. The double-contrast study provides additional information on the width of rotator cuff tears and on degeneration in the tendons in humans. This information is valuable is choosing surgical candidates and electing the best surgical incision. The air-distende capsule permits visualization of the entire intra-articular portion of the biceps tendon. Improved visualization of the articular cartilages is important in evaluating patients with previous anterior shoulder dislocations or inflammatory arthritis.
