Dorsal buckle with ulnar styloid avulsion

Case contributed by Dr Jeremy Jones

Presentation

Fall from bike onto outstretched hand. Pain in the left wrist with reduced motion on passive and active movement.

Patient Data

Age: 8
Gender: Male
Modality: X-ray

On the lateral view, it is easy to see the buckle fracture of the distal radius with buckling of the dorsal cortex and an intact volar cortex.

On the frontal view, there is a transverse lucency through the ulnar epiphysis that represents an ulnar styloid avulsion.

Case Discussion

Buckle fractures are common injuries in children. It is unusual to see an accompanying ulnar styloid avulsion. These usually accompany the adult equivalent of the distal radial buckle fracture: the Colles fracture.
