Figure 24. Figures 24, 25. Large, full-thickness tear of the rotator cuff. (24) Oblique coronal T2-weighted MR image shows a large cuff defect, with the edge retracted far medially (white arrows). Fluid is within both the glenohumeral joint and subacromial-subdeltoid bursa (black arrows). The overlying deltoid muscle (D) nearly apposes the humeral head. A large, full-thickness tear of the rotator cuff was verified at surgery. (25) Oblique coronal proton-density–weighted MR image shows the edges of the torn tendon contrasted with high-signal-intensity fluid. There is delamination, with the undersurface fibers (white arrow) retracted further medially than the bursal-sided fibers (black arrows). A large, full-thickness tear of the rotator cuff was verified at surgery.
