Double-contrast arthrotomography of the shoulder: correlation of radiological and surgical findings in complete rotator cuff tears.

Double-contrast arthrotomography of the shoulder appears extremely valuable; we have verified its accuracy in measurements of complete rotator cuff tears. The first 31 patients so investigated and explored surgically have been retrospectively evaluated. Accurate measurements were found in 85% of the coronal diameters and in 69% of the sagittal ones.
