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.

22-B2.1
definition

Fragmented wedge

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