Multifragmentary, fragmentary segmental fracture of both bones

When both bones are fractured, they are classified independently according to the morphology of each fracture.

For example, the injury illustrated is AO/OTA 2R2C3 2U2C3.

Multifragmentary fractures are usually the result of higher energy trauma, such as motor vehicle accidents, falls from heights, high velocity gunshot injuries, etc. Multifragmentary fractures of both bones are rare and associated with significant soft-tissue damage and should be given high priority.
