This is also the conclusion made by most trials about the scaphoid shift test, several trials have shown us that around 32-36% of the uninjured population have a painless positive scaphoid shift test (only mechanical parameters where measured to determine whether the test is positive or negative during the trial); note that a high correlation between asymptomatic subluxable scaphoid and generalised ligamentous laxity has been noticed. A gritty, clicking or smooth sensation gives you an idea about the state of the articular cartilage and bony form of the joint. Suspected Scaphoid tubercle Fracture. The patient's hand is slightly pronated and the examiner places his thumb on the palmar side of the scaphoid (on the scaphoid tubercule), his other fingers are wrapped around the back of the wrist at the distal part of the radius. [3][8] In the test, an examiner with great experience has been able to predict the presence of absence of the scaphoid shift with an accuracy of 82 and 88% respectively. The scapholunate interosseous ligament is an intra-articular structure (ie, synovial) composed of three regions:[1][5]. 1173185. Epub 2015 Oct 22. The scaphoid shift test. The examiners thumb pressure opposes this normal rotation, causing the scaphoid to shift in relation to the other bones of the carpus. ; 1996; Scapholunate instability - a spectrum of pathology;J. Accid Emerg Med 13:216-219 evidence level: F, S. W. Wolfe, et al. On the basis of their findings, the authors recommend that positive test results be confirmed fluoroscopically. The Watson or Scaphoid Shift Test. Beside the stability, the examiner will also be able to reflect the quality of the adjoining articular surfaces.[2][3]. Variations in stability can be used to grade scaphoid laxity. The scaphoid shift test aka midcarpal shift test is a variation of the Watson Test for scaphoid instability.

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. Use … Pain similar to the patients symptoms during a dorsal shift indicates a symptomatic subluxation of the scaphoid, pain which is less localised combined with normal or limited movement may point in the direction of periscaphoid arthritis or scapho-Iunate advanced collapse pattern. The doctor uses a technique to stabilize the lunate bone and checks for pain, grinding sounds, and/or excessive mobility of the lunotriquetral joint.  |  This scaphoid shift may be subtle or dramatic. DEPARTMENT OF TECHNIQUE The scaphoid shift test 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 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. Extensor carpi radialis at palmar crease. Wrist Injury.

The examiner places pressure on the volar distal pole of the scaphoid and the dorsal lip of the radius, and moves the wrist from ulnar toradial deviation. A truly positive test requires both pain on Orthopaedics and the US Military. [2] [6][7] It is important to perform this technique on both wrists and compare them. The scaphoid bone is the most commonly fractured carpal bone. For the test, the wrist needs to be in slight extension. [4]The scapholunate interosseous ligament(SLIL) is the link between carpal scaphoid and lunate bone. It is used to diagnose scapholunate interosseous ligament instability (SLIL). Pain at rest suggests Scaphoid tubercle Fracture. In this test, the patient’s forearm is placed in pronation. ; 1997; Kinematics of the scaphoid shift test; Journal of Hand Surgery, volume 22A: 801-806 evidence level: C, Min Jong Park; 2002; Radiographic observation of the scaphoid shift test; Journal of Bone and Joint Surgery, volume 85-B: 358-62. evidence level: C.

Scaphoid fracture is not very likely when tubercle palpation does not provoke pain in the snuffbox. [7] A study has shown that the pain associated with the subluxation is significant (p<0,05) to diagnose pathological dynamic scaphoid instability.  |  The scapholunate interosseous ligament(SLIL) is the link between carpal scaphoid and lunate bone. H.W. Clipboard, Search History, and several other advanced features are temporarily unavailable. 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. To perform the scaphoid shift test, the patient should rest his arm with his elbow on the table and his forearm lifted. 2015 Aug;31(3):487-93. doi: 10.1016/j.hcl.2015.04.004. on contralateral side], and right proximal fore-arm muscle wasting.

This will allow the examiner to put pressure on the scaphoid with his thumb. The examiner will feel a significant 'clunk' and the patient will experience pain if the test is positive. positive test seen in patients with scapholunate ligament injury or patients with ligamentous laxity, where the scaphoid is no longer constrained proximally and subluxates out of the scaphoid fossa resulting in pain when pressure removed from the scaphoid, the scaphoid relocates back into the scaphoid fossa, and typical snapping or clicking occurs Would you like email updates of new search results? A positive test can be caused by scapholunate ligament laxity or injury. Though Watson HK. Maneuver. J Hand Surg Am, 18(2):366-368, 01 Mar 1993 Cited by: 9 articles | PMID: 8463609. A.P. [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. In young children and the elderly population scaphoid fractures are rare. Aka: Scaphoid Shift Test, Watson Test. Text Author. To perform the test, the examiner grasps the wrist with their thumb over the scaphoid tubercle (volar aspect of the palm) in order to prevent the scaphoid from moving into its more vertically oriented position in ulnar deviation. complained of localized dorsoradial wrist pain [6/10], had a positive scaphoid shift test (1), mild dorsal wrist edema, a weak and painful grip [20 lbs. [1] Watson first described the test to the American Research in General Orthopedics conference in New Orleans in March 1978. Unilateral scaphoid hypermobility during the so-called scaphoid shift test is felt to represent traumatic instability, especially in the context of wrist injury. Top Contributors - Rik Van der Hoeven, Simisola Ajeyalemi, Laurien Henau, Kim Jackson and George Prudden -Rik Van der Hoeven, The scaphoid shift test is a provocative maneuver used to examine the dynamic stability of the scaphoid and reproduce a patient's symptoms. ; 2005; Severity of Scapholunate Instability Is Related to Joint Anatomy and Congruency; Journal of Hand Surgery Volume 32, Issue 1, Pages 55-60.

COVID-19 is an emerging, rapidly evolving situation. The data demonstrate that despite a high prevalence of positive scaphoid shifts among uninjured individuals, the ability to accurately detect dorsal displacement of the scaphoid using the scaphoid shift test is limited. This article describes a stress test done with the wrist in neutral position, which actively provokes scaphoid instability. In this test, the patient’s forearm is placed in pronation. The floating lunate: arthroscopic treatment of simultaneous complete tears of the scapholunate and lunotriquetral ligaments. 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. Volume 23(1):18-22 evidence level: E. Pappou IP, Basel J, Deal DN. [2][6] When there are doubts and to have clear results about the actual shift, a radioscopy and mostly a fluoroscopy are used to get clear images and information about the shift test.[3][8][9].
