Many might present with a limited range of motion, especially in .Introduction: Supraspinatus muscle atrophy is commonly associated with shoulder disease, but the effect of ageing on atrophy is not well understood. The most sensitive finding in full-thickness tears is thought to be the presence of fluid signal intensity in the location of the rotator cuff on fat-saturated T2-weighted or intermediate-weighted images 5. The fact that stronger associations were not observed in this study is expected given that muscle status is only one element among many determinants of outcome after . The purpose of this study is to evaluate whether atrophy is truly irreversible after rotator cuff repair.To assess the course of supraspinatus muscle atrophy in these 17 patients, MRI was done preoperatively, and 6 and 12 months after surgical repair during physiotherapy.

Supraspinatus atrophy was analyzed on most lateral image of scapular spine (arrowheads) in contact with scapular body (arrows) on oblique sagittal T1-weighted image.Clinical presentation. Occupation ratio of supraspinatus .Hypothesis: We hypothesize that the degree of supraspinatus atrophy, as assessed with the tangent sign will significantly correlate with increasing rotator cuff tear size. Acta Orthop Scand. Assessment is paramount in order to differentiate the structure .Postoperative supraspinatus fatty infiltration, supraspinatus atrophy, and infraspinatus fatty infiltration were moderately well associated with postoperative functional outcome measures. Therefore, it is possible to diagnose rotator cuff tear and determine the treatment method by detecting the supraspinatus fossa and muscle area through MRI as a clinical index, and then .8 months; observers 1 and 2: P < .Partial tears can be just 1 millimeter deep (only about 10 percent of a tendon), or can be 50 percent or deeper.
