De quervain syndrome

[Ernesto]

De Quervain syndrome is stenosing tenosynovitis of the short extensor tendon (extensor pollicis brevis) and long abductor tendon (abductor pollicis longus) of the thumb within the first extensor compartment.
(See also Overview and Evaluation of Hand Disorders.)
De Quervain syndrome usually occurs after repetitive use (especially wringing) of the wrist, although it occasionally occurs in association with rheumatoid arthritis. It commonly manifests in parents of newborns because of repetitive lifting with wrists in radial deviation.
The major symptom of De Quervain syndrome is aching pain at the wrist and thumb, aggravated by motion. Tenderness can be elicited just proximal to the radial styloid process over the site of the involved tendon sheaths.
Diagnosis of De Quervain syndrome is highly suggested by the Finkelstein test. The patient adducts the involved thumb into the palm and wraps the fingers over the thumb. The test is positive if gentle passive ulnar deviation of the wrist provokes severe pain at the affected tendon sheaths.
