title: Pisiform and hamulus fractures: easily missed wrist fractures diagnosed on a reverse oblique radiograph.
abstract: We present a review of the current literature involving fractures of the pisiform and hook of the hamate. This is highlighted by two cases in which the fracture lines are seen only on the reverse oblique wrist radiograph, a view obtained with the wrist in a supinated rather than a pronated position. These fractures are not seen on standard two or three view wrist examination. Both of these fractures were initially missed in the emergency department. Serious sequelae can result from both of these injuries and can be avoided if diagnosed acutely. The reverse oblique radiograph can be quick, cost-effective, and diagnostic in this setting. If properly treated by immobilization or excision, the results can be excellent.
