To test for midcarpal instability on the right wrist, the examiner stabilizes the patient's forearm, with the left hand in a pronated position. [10] With the patient's wrist in 15° of ulnar deviation, the examiner's right thumb exerts volarward pressure at the level of the distal capitate. The wrist is then simultaneously axially loaded at the metacarpals and ulnarly deviated. The result is positive if a painful clunk occurs that reproduces the patient's symptoms.
