Answer

Answer

The ulnar styloid can be palpated along the volar ulnar aspect of the ulnar head with the wrist radially deviated. Tenderness, swelling, or ecchymosis may be present on examination of a styloid fracture. Peripheral TFCC tears of the ulna (Palmer type IB injury) cause tenderness over the ulnar styloid. TFCC tears of the ulnolunate and ulnotriquetral ligaments (Palmer type IC injury) result in tenderness over the volar aspect of the distal ulna.
