Distal radial fracture (summary)

Distal radial fractures are a relatively common group of injuries that usually occur following a fall. The commonest of these fractures is a transverse extra-articular fracture and where there is associated dorsal angulation, this is termed a Colles fracture.

    • in some cases, internal fixation is needed

The commonest fracture of the distal radius is a transverse extra-articular fracture which is usually seen as a transverse lucency across the distal radius in the region of the metaphysis.

If there is impaction, the fracture may be seen as a sclerotic line.

Transverse fractures may be angulated - dorsal angulation is commonest (a Colles fracture). There may be fracture extension into the joint which is important to pick up.
