Extraarticular fracture,  metaphyseal simple (AO/OTA 41A2)

Simple fractures of the proximal metaphysis are classified by the AO/OTA as 41A2 fractures. They may be low or high velocity injuries. High velocity fractures are displaced, unstable, difficult to treat and always require surgical stabilization.
