Extraarticular wedge or multifragmentary fracture of the radius

These metaphyseal fractures are extraarticular, but multifragmentary. They are subclassified according to the degree of fragmentation and compression of the metaphysis:

• Impacted with axial shortening (AO/OTA 2R3A3.1)
• Angulated with a wedge fragment (AO/OTA 2R3A3.2)
• Multifragmentary fracture (AO/OTA 2R3A3.3)

These injuries may be associated with an ulnar injury. This is usually a fracture of the ulnar styloid process, but other ulnar fractures are possible.
