Abstract
Isolated fracture of the humeral trochlea was originally described by Laugier in 1853 and has since been known as Laugier’s fracture.5 The trochlea rarely fractures in isolation, because it has no muscular or ligamentous attachments and the ulnohumeral joint is not subject to shear forces that occur at the radiocapitellar joint. Thus, trochlear fractures are usually accompanied by other injuries to the elbow. Grant and Miller3 reported a case of an osteochondral fracture of the trochlea occurring as part of a fracture-dislocation of the elbow.
