De Quervain tenosynovitis affects the tendons in the first dorsal extensor compartment of the wrist, namely the tendons of abductor pollicis longus and extensor pollicis brevis muscles, at the distal end of the radius. Pain and swelling occur over the radial aspect of the wrist, extending to the thumb.
De Quervain tenosynovitis often occurs in people who perform repetitive manual tasks. It commonly occurs in the postpartum period and is probably caused by repeated radial and ulnar deviation of the wrist during gripping movements (eg during breastfeeding). Less frequently, it can occur in pregnancy.
