Compression of the ulnar nerve by an aneurysm. A case of late complication after a supracondylar fracture

Abstract

A 26-year-old man with a history of a supracondylar fracture of the left humerus 10 years ago had weakness and tingling of the fourth and fifth fingers of the left hand due to ulnar-nerve entrapment confirmed by electromyography. Angiography revealed complete obstruction of the brachial artery at the elbow and an aneurysm in the ulnar collateral artery at the medial epicondyle of the humerus. After reconstruction of the brachial artery and resection of the aneurysm, recovery was uneventful. Electromyography 6 months postoperatively was normal. © 1992 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
