[Rotator cuff rupture. Diagnostic imaging]

Abstract

Conventional radiography, ultrasound, Magnetic Resonance (MR), Arthrography Computed Tomography (Arthro-CT) and Arthrography Magnetic Resonance (Arthro-MR) are available for diagnosis of rotator cuff tears. Our purpose is to assess the specificity and sensitivity of these examinations and if they could give to the surgeon all the informations to select the more accurate treatment. We have evaluated retrospectively the images of 68 patients, 43 male and 25 female (average age 51 years), which then have been surgically treated for rotator cuff pathology. On the basis of our findings, we think that conventional radiography and ultrasound are excellent in a first evaluation. MR images, particularly in the coronal and sagittal oblique planes, are able to demonstrate partial or complete rotator cuff tears. The use of intra-articular contrast medium (arthro-CT, arthro-MR) should be reserved for partial lesions on specific cases.
