is used to diagnose DeQuervain's tenosynovitis
in people who have wrist pain
. To perform the test, the examining physician grasps the thumb and the hand is ulnar deviated sharply, as shown in the image. If sharp pain occurs along the distal radius (top of forearm, close to wrist; see image), DeQuervain's tenosynovitis is likely.
Some other doctors ask their patients to flex their thumb and clench their fist over the thumb followed by ulnar deviation for Finkelstein's test.Purpose:
Finkelstein's test is one way to determine if there is tenosynovitis
in the abductor pollicis longus
and extensor pollicis brevis
tendons of the wrist. These two tendons belong to the first dorsal compartment.
First dorsal compartment: abductor pollicis longus and extensor pollicis brevis.
Second dorsal compartment: extensor carpi radialis longus
and extensor carpi radialis brevis
Third dorsal compartment: extensor pollicis longus
Fourth dorsal compartment: extensor digitorum
and extensor indicis
Fifth dorsal compartment: extensor digiti minimi
Sixth dorsal compartment: extensor carpi ulnaris
.Origin/Background on Finkelstein:
Finkelstein's test was described by Harry Finkelstein
(1865-1939), an American surgeon
, in 1930.Finkelstein, H., (1930): Stenosing tenosynovinitis at the radial styloid process. The Journal of Bone and Joint Surgery
, 1930, 12
: 509-540. A similar test was previously described by Eichoff, in which the thumb is placed in the palm of the... Read More
