Middle phalanx - Distal, unicondylar

General considerations

Unicondylar fractures of the middle phalanx can be oblique, (short or long), or comminuted. Typically they are the results of an axial load combined with lateral angulation of the finger.

These fractures are rare, but difficult to treat. There is an increased risk of joint stiffness resulting from these fractures.
