Sonographic Findings in Subcoracoid Impingement Syndrome: A Case Report and Literature Review.
Subcoracoid impingement syndrome is a rare and underrecognized cause of anterior shoulder pain. Currently, subcoracoid impingement syndrome is understood to involve impingement of anatomic structures such as the subcoracoid bursa and subscapularis tendon within the coracohumeral space, and there are no reports of sonographic findings in subcoracoid impingement syndrome other than the impingement of thickened subscapularis bursa. Here we report a case of subcoracoid impingement syndrome, including a novel sonographic finding, arthroscopic findings, and a proposed pathophysiology.
