Finkelstein's test

[1] Classical descriptions of the Finkelstein's test are when the examiner grasps the thumb and ulnar deviates the hand sharply.

[1] If sharp pain occurs along the distal radius (top of forearm, close to wrist; see image), de Quervain's tenosynovitis is likely.

If sharp pain occurs along the distal radius, Quervain's tenosynovitis is suspected.

[5] A similar test was previously described by Eichhoff, in which the thumb is placed in the palm of the hand and held with the fingers, and the hand is then ulnar deviated (see images), causing intense pain over the radial styloid which disappears if the thumb is released.

[8] This is significant because Eichhoff's test may create pain in other tissues to come back a false positive or may come back negative though de Quervain’s syndrome is still suspected, the patient can radially deviate against resistance to possibly reproduce pain.
