[The sonography of rotator cuff ruptures. The correlation of the sonographic, arthrographic and intraoperative findings in rotator cuff ruptures].

We have compared the findings of sonography, arthrography and at surgery in 66 cases of rotator cuff rupture in order to clarify the sonographic and radiological signs. Preoperative sonography was better than arthrography at demonstrating a partial rupture and at showing the extent of the lesion.
