Cuff tear size, atrophy and fatty infiltration are related

Supraspinatus atrophy as a predictor of rotator cuff tear size: an MRI study utilizing the tangent sign

These authors performed a retrospective review assessing presence of muscle atrophy, fatty infiltration and the size of rotator cuff tear in 34 patients. The tangent sign is a simple method for characterizing the degree of muscle atrophy. These variables were related. 

These findings again help us understand the challenges faced in trying to achieve a durable, functional repair in large tears with atrophic, fatty infiltrated musculature.
