Subcoracoid Impingement: Diagnosis and Ultrasound-guided Injection in Throwing Athletes
Abstract
Subcoracoid impingement is a rare condition, therefore, its diagnosis poses a challenge to the orthopedic surgeon. It manifests with dull pain in the subcoracoid region and pain on palpation in the coracoid process as a result of impingement of the subscapularis muscle between the coracoid process and the lesser tubercle of the humerus. The objective of this technical note is to describe an alternative diagnosis and ultrasound-guided injection for throwing athletes with subcoracoid impingement.Downloads
