pisiform fracture

Pisiform fractures are an uncommon type of fracture involving the carpal bones.

Epidemiology

They are only thought to account for ~0.2% of all carpal fractures. Approximately 50% occur in association with other carpal fractures.

Very rarely the pisiform may be dislocated without fracture and displaced radially.

Radiographic features

Plain radiograph

Some can be occult on plain film. The pisotriquetral joint is best seen in the lateral view with 30 degrees supination or using the carpal tunnel view.

Treatment and prognosis

They are usually managed by immobilization in either a plaster cast or a wrist splint. In certain circumstances, placement of a pin-screw or excision is performed.
