MRI observations of the rotator cuff tear showing a high signal intensity on the supraspinatus muscle belly (SMB) were examined before and after surgery.The subjects were eleven patients a the massive and global rotator cuff tear of the shoulder aged between 52-76 years old (mean, 65.4 years old). They revealed a high signal intensity on the SMB when compared to the trapezius muscle belly in T2-weighted images using an MRT-200FX, 1.5T (Toshiba) or a GE Signa, 1.5T.Their pre- and post- operative conditions were evaluated according to their JOA score, and a high signal intensity of the SMB on MRI was observed after surgery.No remarkable changes in the intensity of the SMB on MRI in the nine cases with high post-operative JOA scores. On the other hand, in the two cases with low points, the high signal intensity had increased.A persistent tear of the rotator cuff causes fibrosis and fatty degeneration in the SMB with a high signal intensity on MRI through the post-operative periods.
