Osteochondroma of the first rib with pseudarthrosis with the clavicle: a rare cause for shoulder pain: a case report

Abstract

Shoulder pain with abduction is a common clinical sign associated with an impingement syndrome. This article describes a patient with an osteochondroma of the first rib that formed a pseudarthrosis with the clavicle, which limited its rotation, leading to pain with abduction of the shoulder. The available literature concerning this rare phenomenon is discussed, and the recommended treatment outlined.
