PASTA lesion
Pronunciation: PASS-tuh
Partial articular-sided supraspinatus tendon avulsion, a specific type of rotator cuff tear pattern.
Full Definition
PASTA lesion is an acronym for Partial Articular-sided Supraspinatus Tendon Avulsion, representing a specific pattern of rotator cuff pathology. This lesion involves a partial-thickness tear of the supraspinatus tendon that occurs on the articular (joint) side, typically at the tendon's insertion on the greater tuberosity. PASTA lesions are commonly seen in overhead athletes and may be associated with impingement syndrome. The tear pattern is characterized by fraying and delamination of the tendon fibers, often extending into the deeper layers while leaving the bursal surface intact. Diagnosis is typically made through MRI or arthroscopy, and treatment may range from conservative management to arthroscopic repair depending on tear size and symptoms.
Usage
Usage note: Acronym should be defined on first use; specific to supraspinatus tendon pathology.
