Extraarticular, wedge, intact or fragmentary

This fracture type is classified by the AO/OTA as 13A3.1 (intact wedge) or 13A3.2 (fragmentary wedge).

In osteoporotic bone, the distal articular fragment may be very short, and metaphyseal comminution of varying degree may be present in either the ulnar or radial column.
The most difficult task is to stabilize a very short articular fragment when the bone quality is poor.
