Wedge fracture of one bone, with a simple or wedge fracture of the other
When both bones are fractured, they are classified independently according to the morphology of each fracture.
Forearm fractures are often the result of indirect mechanisms, such as a fall onto an outstretched hand, sporting activities, etc.
When both bones are fractured there is increased instability of each of the fractures. They may very rarely be associated with an instability of the distal radioulnar joint (DRUJ) or of the radiocapitellar joint.
