RESUMEN
We review the technique of double-contrast arthrotomography (DCAT) including reference to a new, superficial and bevel-oriented puncture and the use of a special density compensation filter. We have found it possible to demonstrate the varieties, size and exact location of rotator cuff tears in the coronal and sagittal planes. Adaptation of the method to studies of the glenoid labrum also yields excellent results. DCAT is now the best technique of shoulder arthrography.

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.

We describe a silicone filter that overcomes peripheral overpenetration in radiography of the shoulder. With proper angulation, its use facilitates better demonstration of the acromiohumeral window and adjacent structures.
