ROTATOR CUFF TENDINO PATHY

ROTATOR CUFF TENDINOPATHY

Partial, undersurface tear of the rotator cuff. US image shows mixed echogenicity of the undersurface of the cuff (straight arrows) that reflects torn cuff fibers and adjacent fluid. The bursal fibers are intact (curved arrows).

Staging, Grading or Classification Criteria

Partial-thickness tear of the rotator cuff. Oblique coronal T2-weighted MR image shows an undersurface tear with a

discrete flap (arrows) that was verified at surgery .

Partial rotator-cuff tear, indirect MR arthrography, oblique-coronal plane. Intravenous contrast media injection, 10-

15min motion and fat suppression shows, thinned, irregular-shaped supraspinatus tendon, concordant with

partial tearing .

ROTATOR CUFF PARTIAL THICKNESS TEAR

Large, full-thickness tear of the rotator cuff. Coronal (longitudinal) US image shows a large cuff defect filled with fluid and debris (straight arrows). Also apparent are the medially retracted edge of supraspinatus tendon (curved arrow), near apposition of deltoid muscle (D) to the humeral head, and loss of outer convexity.

Massive full-thickness tear of the rotator cuff. (A) US image demonstrates a massive rotator cuff tear, the gap filled with hypoechoic fluid (straight arrows). The underlying hyaline cartilage is exposed (naked cartilage sign) (curved arrows). (B) US image shows apposition of the deltoid muscle (D) to the underlying humeral head (solid arrows). An osseous excrescence appears at the articular

margin (open arrow).
