Purpose[edit | edit source]
De Quervain's Tenosynovitis is a condition involving the abductor pollicis longus and extensor pollicis brevis tendons in the first extensor compartment of the wrist[1]. Different tests has been used to identify De Quervain's disease, with the Finkelstein's test being one of the common diagnostic tests[2]. The Finkelstein's test is often confused with the Eichhoff's test[2][3], thus the Wrist hyperflexion & Abduction of the Thumb test is developed in 2014 as an alternative test for De Quervain's disease[3].
Technique[edit | edit source]
Procedure[3]:[edit | edit source]
- The patient is seated in a comfortable position.
- They are asked to actively hyperflex their wrist and abduct their thumb.
- The examiner then resists the movement with their index finger.
Interpretation[3]:[edit | edit source]
Pain reproduction indicates positive test for De Quervain's Tenosynovitis
Evidence[edit | edit source]
A study found that The WHAT test is more accurate as compared to traditional diagnostic test for De Quervain's, with a sensitivity score of 0.99 and specificity score of 0.29[3].However, the study involved a small sample size and only two experienced surgeons. Therefore, further investigations need to be done to confirm the reliability and validity of the test[3].
