Partial articular, frontal/coronal, capitellum and trochlea

This fracture type is classified by the AO/OTA as 13B3.3.

These fractures are often associated with impaction of the posterior part of the lateral column, and/or the posterior trochlea.

Most apparently isolated capitellar fractures are more complex than they initially appear.
Computed tomography - particularly 3D CT - can help to define the fracture anatomy and facilitate planning of the surgery.
