Double-contrast Arthrography of the shoulder.

Although single-contrast arthrography has been advocated since 1933 it is the use of water-soluble contrast agents together with the simultaneous injection of air which have made shoulder arthrography a rather painless procedure yielding much additional information. Double-contrast arthrography has been used at our institution to demonstrate or exclude lesions of the rotator cuff, the biceps tendon, the capsule, the articular surfaces of the joint and adhesive capsulitis. In this review the technique and results in 58 consecutive cases are presented.
