Description: De Quervain's TenosynovitisDe Quervains tenosynovitis is a stenosing tenosynovitis of unknown aetiology which occurs in the first dorsal compartment at the level of the radial styloid. It involves the common extensor sheath containing the tendons of abductor pollicis longus and extensor pollicis brevis. There is palpable thickening of the tendon sheath with painful limitation of extension of the thumb. Treatment frequently requires division of the thickened sheath, care being taken to avoid the adjacent superficial radial nerve. Division of the sheath produces no functional impairment.
