Through repetitive movements of the thumb and wrist, the two tendons involved in these movements can swell and put pressure on nearby nerves causing pain known as De Quervain’s tenosynovitis. This pain is the result of inflammation and irritation from the friction of the thumb tendons against the bone.
Patients with De Quervain’s tenosynovitis typically have swelling at the base of the thumb, and numbness at the back of the thumb and index finger. Other symptoms usually include pain with thumb function.
De Quervain’s tenosynovitis can usually be treated without surgery. Through the use of anti-inflammatory medications, splinting, topical creams, hand therapy, and/or steroid injections. In rare cases, surgery may be necessary to release the tendon and relieve symptoms.
