Transverse capitellar shear fracture with interposed radial head fragment. A previously unclassified type of distal humeral fracture

Abstract

This is the first description of a transverse shear fracture on the radial capitellum. So far only fractures in the frontal plane have been classified. MRI examinations in radial head fractures type Mason II–III shows that osteocondral fractures of radial capitellum are much more common than previously thought (10–30%). Treatment of this type of fracture is similar to frontal shear fractures.
