Combined shear fractures of the trochlea and capitellum associated with anterior fracture-dislocation of the elbow.

This article presents two unusual cases of combined shear fractures of the trochlea and capitellum associated with anterior fracture-dislocation of the elbow. The mechanism of injury was thought to be a fall on the dorsum of a partially flexed forearm, in which the trochlea and capitellum are displaced by the fractured olecranon and the radial head.
