Isolated Tear of Coracobrachialis: An Unusual Presentation of Glenohumeral Internal Rotation Deficit

Abstract

AbstractAn isolated injury to the coracobrachialis is an exceedingly uncommon occurrence, with only a handful of case reports documented in the literature. The majority of the reported cases attribute the injury to either direct trauma to the affected area or the contraction of the muscle, leading to the rupture of the muscle belly. In this article, we reported a case of indirect traumatic partial rupture of the coracobrachialis muscle, accompanied by a substantial hematoma at the proximal myotendinous junction had an unusual presentation of glenohumeral internal rotation deficit. To the best of our knowledge, no other case of isolated coracobrachialis injury has been reported in a bowler/cricketer.
