1Preliminary remark

Comminuted fractures of the distal ulna usually occur in combination with distal radial fractures.

In multifragmentary ulnar fractures, there is instability and shortening, and bridge plating is the chosen means of stable internal fixation.

Attention should be paid to restoring correct rotation and correct length in relation to the radius.

Complete dislocation of the radiocarpal joint is often associated with disruption of the distal radioulnar joint (DRUJ).
