De quervain tenosynovitis of the wrist.

De quervain disease, or stenosing tenosynovitis of the first dorsal compartment of the wrist, is a common wrist pathology. Pain results from resisted gliding of the abductor pollicis longus and the extensor pollicis brevis tendons in the fibro-osseus canal. de Quervain tenosynovitis of the wrist is more common in women than men. Diagnosis may be made on physical examination. Radiographs are helpful in ruling out offending bony pathology. Nonsurgical management, consisting of corticosteroid injections and supportive thumb spica splinting, is usually successful. In resistant cases, surgical release of the first dorsal compartment is done, taking care to protect the radial sensory nerve and identify all accessory compartments. Repair of the extensor retinaculum by step-cut lengthening or other techniques is rarely required.
