De Quervain’s Tenosynovitis
De Quervain’s syndrome is a stenosing tenosynovitis of the first extensor compartment containing abductor pollicis longus and extensor pollicis brevis. Pain is felt over these tendons on the radial border of the wrist, particularly with thumb and wrist movements. Finkelstein’s test, passive adduction of the thumb into the palm and ulnar deviation of the wrist, will usually exacerbate symptoms. Injection therapy can be diagnostic and therapeutic.
