Commonly fractures among the carpal bones are scaphoid (7080%), triquetral (7-20%) and trapezium (5%)\ Fractures of the pisiform are extremely rare and frequently associated with other carpal or distal radial injuries.
The intrinsic ligaments at the proximal margins of the scaphoid, lunate, and triquetral bones arrest the proximal flows of contrast, preventing communication with the radiocarpal compartment.
