Supracondylar Process of the Humerus Causing Brachial Artery Compression and Digital Embolization in a Fast-Pitch Softball Player

Abstract

The supracondylar process of the humerus is a rare abnormality found in 0.4–2.7% of the population. It has been documented to cause neurovascular compression in the upper extremity owing to its local impingement on the median nerve and brachial artery at its medial location on the humerus just proximal to the elbow. The authors report the first known case of digital ischemia from embolization of thrombus caused by local compression of the brachial artery attributed to a supracondylar process.
