Extraarticular, simple, oblique

This fracture type is classified by the AO/OTA as 13A2.2.

This fracture may occur in a young patient with strong bone. Shear forces lead to an oblique separation of the metaphyseal/articular block from the shaft. Due to strong rotational forces at the level of the elbow, stabilization with plates on the ulnar and radial columns is preferred. The plates should be applied in a compression mode.

The obliquity of the fracture plane can be in either direction:

  • Obliquely downward and medially
  • Obliquely downward and laterally
