Hook of hamate pull test

Hook of hamate pull test. The patient's hand is placed palm up on an examination table with the wrist in full active ulnar deviation, and the ring and little fingers flexed. The examiner then resists the patient's active flexion (of the digitorum profundus) in these two fingers. During the maneuver, pain focused at the hook of the hamate region (and sometimes radiating into the palm or wrist) suggests fracture of the hamulus.
