The ulnohumeral arthroplasty: technical tips for safely managing the brachial artery

Abstract

One surgical option to manage idiopathic osteoarthritis of the elbow is an ulnohumeral arthroplasty. A potential complication to avoid during this procedure is inadvertent over penetration of the anterior cortex of the humerus. If this occurs, injury to the median nerve and brachial artery is possible as these structures may lie within 7 mm of the anterior humerus. This surgical technique describes technical tips in regards to patient positioning and specific instrument usage that serve to diminish the risk of this catastrophic complication occurring by allowing these critical neurovascular structures to fall away from the anterior humerus.
