Rim rent tear of rotator cuff
Citation, DOI & article data
A rim rent tear of the rotator cuff, also known as partial articular surface tendon avulsion (PASTA), is a specific subtype of partial-thickness rotator cuff tear that involves the articular surface footprint at the site of tendon attachment into the greater tubercle 2. This sort of tear is relatively common and also can involve the infraspinatus tendon 3.
May be seen as an echogenic edge and a cortical defect at the footprint.
May be seen as a gap at the attachment (footprint).
