What is it?
De Quervain’s Tenosynovitis is the irritation of the two tendons that insert at the base of the thumb as they pass through the extensor sheath. The extensor pollicis brevis and the abductor pollicis longus muscles are responsible for lifting the thumb up and away from the palm. Repetitive movements of the thumb and wrist, as well as activities requiring pinching, can cause pain and swelling around the tendons. Aggravating activities include repetitive wrist movements, such as in the example above, and day-to-day activities such as writing, carrying boxes, turning keys and making the bed.
