Relief of pressure will allow the scaphoid to slip back into place with a clunk. [2] [6][7] It is important to perform this technique on both wrists and compare them. The patient's wrist is then moved from ulnar to radial deviation. In young children and the elderly population scaphoid fractures are rare. Press while moving wrist from ulnar to radial deviation.

[1] Watson first described the test to the American Research in General Orthopedics conference in New Orleans in March 1978. My co-worker asked, “How should we treat this patient?” To reduce the persistent pain [6/10] H.W. That is usually the journal article where the information was first stated. WBC Differential.

It ensures stability of the scapholunate joint and helps keep the entire wrist stabilized. scaphoid shift test (Watson's test) tests for scapholunate ligament tear examiner places thumb on distal pole of scaphoid on palmar side of wrist and applies constant pressure as the wrist is radially and ulnarly deviated dorsal wrist pain or "clunk" may indicate instability 2005 Sep;30(5):937-42. doi: 10.1016/j.jhsa.2005.05.016. J Hand Surg Am. Apprehension and/or a painful clunk during the movement demonstrates dynamic subluxation. 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. The test, however, is subjective, and requires considerable experience to correlate the degree of scaphoid mobility with pathologic significance. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. If the The scaphoid bone is the most commonly fractured carpal bone. The Scaphoid Shift Test - PubMed 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. Midcarpal Instability: A Comprehensive Review and Update. 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. Maneuver. IV. Both men will be representing Nova at CSM 2016 with poster presentations. Epub 2008 Dec 23. COVID-19 is an emerging, rapidly evolving situation. 1173185. Wagner Grading System for Diabetic Foot Infections. To perform the scaphoid shift test, the patient should rest his arm with his elbow on the table and his forearm lifted. 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. Depending on the extent of ligamentous injury, there is either diffuse tenderness of the carpus or point tenderness over the scapholunate interval. J Hand Surg Am, 18(2):366-368, 01 Mar 1993 Cited by: 9 articles | PMID: 8463609. A truly positive test requires both pain on Original Editors- Rik Van der Hoeven 2015 Aug;31(3):487-93. doi: 10.1016/j.hcl.2015.04.004. The examiners thumb pressure opposes this normal rotation, causing the scaphoid to shift in relation to the other bones of the carpus. Epub 2015 Oct 22. For completeness, the test must be performed on both wrists for comparison. 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. The test is found helpful during the examination of the wrist and more specifically the scaphoid. In this test, the patient’s forearm is placed in pronation. The scapholunate interosseous ligament is an intra-articular structure (ie, synovial) composed of three regions:[1][5]. 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 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. Variations in stability can be used to grade scaphoid laxity. Hand Clin. [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. Lane LB. Indication. 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. It is used to diagnose scapholunate interosseous ligament instability (SLIL). The Watson scaphoid shift test can be helpful. 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.
