Finkelstein's test is a test used to diagnose de Quervain's tenosynovitis in people who have wrist pain. Classical descriptions of the Finkelstein's test are when the examiner grasps the thumb and ulnar deviates the hand sharply. If sharp pain occurs along the distal radius (top of forearm, close to wrist; see image), de Quervain's tenosynovitis is likely. Finkelstein's test is commonly confused with Eichhoff's test: the Eichhoff's test is typically described as the examiner grasping and ulnar deviating the hand when the person has their thumb held within their fist. If sharp pain occurs along the distal radius, Quervain's tenosynovitis is suspected. Eichhoff's test may produce false positive results, while a Finkelstein's test performed by a skilled practitioner is unlikely to produce a false positive.
