Triquetral Fracture

• The triquetrum is the second most commonly fractured carpal (scaphoid is first).
• Fractures are usually avulsions from the dorsal surface.
• A lateral view of the hand is typically required for diagnosis.
• Soft tissue abnormalities of the dorsum of the wrist can aid in diagnosis.

Look for the fracture in the following radiographs.
Remember that the triquetrum is just distal and medial to the ulna.
