# Wedge fracture of the radius with no dislocation

## General considerations

The wedge fragment may be intact or fragmented.

Forearm fractures are often the result of indirect mechanisms, such as a fall onto an outstretched hand, sporting activities, etc.

Often these radial fractures are located where the cross-section of the radius is circular. At this level of the radius the main stress is torsional, because the bending loads are carried by the ulna.

## Intact wedge

Radial shaft fractures where the wedge is intact are classified as AO/OTA 2R2B2.

## Fragmented wedge

Radial shaft fractures where the wedge is fragmented are classified as AO/OTA 2R2B3.
