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

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.
