De Quervain's tenosynovitis causes pain in tendons around the base of the thumb, on the inside of the wrist and forearm. Both terms refer to inflammation along the thumb. When the tendons around the base of the thumb are irritated or constricted, they swell.
This tendon straightens the end joint of the thumb and also helps pull the thumb in towards the index finger. In this area it is confined to a tight tunnel. See diagram.
Our hands connect us with the world. We work with our hands and communicate with our hands. The wear and tear from all that use can sometimes cause painful conditions, and women are particularly prone to develop two of these: de Quervain's pronounced deh-KWER-vins tenosynovitis and stenosing tenosynovitis or trigger finger.
Back to Health A to Z. If any of the tendons in your hand are damaged, surgery may be needed to repair them and help restore movement in the affected fingers or thumb. Tendons are tough cords of tissue that connect muscles to bones.
The ring finger is often one of the fingers affected. The condition is also known as stenosing tenosynovitis. Tendons are bands of tissue that attach muscles to bones.
Tendonitis usually occurs when you repeatedly injure or overuse a tendon. Tendons are the tissue that attach your muscles to your bones. Tendonitis in your finger can occur from repetitive straining due to leisure or work-related activities.
De Quervain's tenosynovitis refers to inflammation of the tendons in the thumb. The condition makes it painful when a person moves their thumb. There are some exercises that people can do at home to help alleviate the symptoms.
A deep cut on the palm side of your fingers, hand, wrist, or forearm can damage your flexor tendons, which are the tissues that help control movement in your hand. A flexor tendon injury can make it impossible to bend your fingers or thumb. Tendons are tissues that connect muscles to bone. When muscles contract, tendons pull on bones.
If any of the tendons in your hand are damaged, surgery may be needed to repair them and help restore movement in the affected fingers or thumb. Tendons are tough cords of tissue that connect muscles to bones. When a group of muscles contract tightenthe attached tendons will pull on certain bones, allowing you to make a wide range of movements.
In human anatomythe extensor pollicis longus muscle EPL is a skeletal muscle located dorsally on the forearm. It is much larger than the extensor pollicis brevisthe origin of which it partly covers and acts to stretch the thumb together with this muscle. The extensor pollicis longus arises from the dorsal surface of the ulna and from the interosseous membrane next to the origins of abductor pollicis longus and extensor pollicis brevis. Passing through the third tendon compartment,  lying in a narrow, oblique groove on the back of the lower end of the radius it crosses the wrist close to the dorsal midline before turning towards the thumb using Lister's tubercle on the distal end of the radius as a pulley.
