MR arthrography: correlation between anatomic intraarticular variants of the long head of the biceps tendon (long head biceps tendon) and superior labral anterior to posterior (SLAP) lesions

Abstract

Highlights Anatomical variants of the intraarticular portion of the long head of the biceps tendon should be studied with MR arthrography. Some anatomical variants are more frequently associated with supraequatorial lesions. The higher frequency of lesions in the presence of certain anatomical variants is probably related to the limited excursion of the intraarticular long head biceps tendon.
