He will be demonstrating a Watson Scaphoid Shift Test. Would you like email updates of new search results? This article describes a stress test done with the wrist in neutral position, which actively provokes scaphoid instability. J Hand Surg Am. Kinematics of the midcarpal and radiocarpal joints in radioulnar deviation: an in vitro study. The ligaments that are thought to provide the principle support to the scaphoid are the radioscaphocapitate ligament, the scaphoid-trapezoid-trapezium ligament and the scapholunate interosseous ligament. [2][6]The hand is put into ulnar deviation and in slight dorsal flexion; in this position the scaphoid lies almost 'in line' with the ulna. For the test, the wrist needs to be in slight extension. Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare provider. There were, however, 18 patients with dynamic scapholunate instability in whom the standard films were normal but dorsal stress radiography showed gap greater than 3mm between the scaphoid and lunate. Though Watson HK. [1] Watson first described the test to the American Research in General Orthopedics conference in New Orleans in March 1978. J Hand Surg Am. Because there is only this one, small blood supply, a fracture in the center of the bone can actually sever … Locate Scaphoid tubercle. Suspected Scaphoid tubercle Fracture. The scaphoid shift test is useful for the evaluation of the sta-bility of the scaphoid in the injured wrist.1-5 It involves radial deviation of the wrist with the examiner’s thumb opposing the normal volar rotation of the distal scaphoid, causing the scaphoid to shift dorsally.6 Although this pro- scaphoid. It can be injured by a fall or a sudden load on the wrist and can occur together with a distal radius or carpal bone fracture. Thumb on Scaphoid tubercle (volar) Index finger on dorsum behind Scaphoid. Lane LB. The scaphoid test described by Watson has generally been accepted as the definitive test for scaphoid instability and uses pressure against the scaphoid tubercle as the wrist moves from ulnar to radial deviation for the evaluation. It is used to diagnose scapholunate interosseous ligament instability (SLIL). The test is found helpful during the examination of the wrist and more specifically the scaphoid. Gleeson, et al. Kitay A, Wolfe SW. Scapholunate instability: current concepts in diagnosis and management. Beside the stability, the examiner will also be able to reflect the quality of the adjoining articular surfaces.[2][3]. NIH H. Kirk Watson, et al. Wrist Injury. as compared to 60 lbs. The Watson test: painful dorsal scaphoid displacement as the wrist is moved from ulnar to radial deviation with palmar pressure on the tuberosity. Scaphoid Shift Test. on contralateral side], and right proximal forearm muscle wasting. Scaphoid fracture is not very likely when tubercle palpation does not provoke pain in the snuffbox. The scaphoid’s blood flow comes from a small vessel that enters the most distant part of the bone and flows back through the bone to give nutrition to the bone cells.

A gritty, clicking or smooth sensation gives you an idea about the state of the articular cartilage and bony form of the joint. Epub 2015 Oct 22. Use the same hand as the patient’s affected hand (suspicious of a right scaphoid problem? [2][4][7]This stress is overcome in a normal wrist (minimal movement can be tolerated), but results in a dorsal displacement ('shift') of the scaphoid in relation to the other carpal bones in the wrist of a patient with ligamentous laxity. ; 1994; Scaphoid Shift in the Uninjured Wrist; Journal of Hand Surgery, volume: 19A, 604-606 evidence level: C, Wozasek GE, Laske H; 1991; The ligaments of the scaphoid bone; Handchir Mikrochir Plast Chir. WATSON / SCAPHOID SHIFT TEST FOR SL LIGAMENT RUPTURE OF THE WRIST The scapholunate ligament is a very strong ligament between the scaphoid and the lunate and important for the stability of the wrist.
