Luxation of the Elbow Complicated by Proximal Radio-Ulnar Translocation

Abstract

Luxation of the elbow complicated by proximal radio-ulnar translocation is a rare entity. The clue to diagosis is the reversed position of the bones of the proximal forearm. In the a.p. projection the radial head articulates with the trochlea and the ulna with the capitellum. This unexpected anatomic relationship is easily overlooked. Delayed reduction may result in permanent impairment of elbow motility. Our experience with three recent cases is presented.
