De Quervain’s tenosynovitis occurs when the tendons around the base of the thumb are irritated or constricted. Swelling of the tendons, and the tendon sheath, can cause pain and tenderness along the thumb side of the wrist. This is particularly noticeable when forming a fist, grasping or gripping something, or when turning the wrist. Two of the main tendons to the thumb pass through a tunnel (or series of pulleys) located on the thumb side of the wrist.

Tendons are rope-like structures that attach muscle to bone. Tendons are covered by a slippery thin soft-tissue layer, called synovium. This layer a9llows the tendons to slide easily through a fibrous tunnel called a sheath. Any swelling of the tendons and/or thickening of the sheath, results in increased friction and pain with certain thumb and wrist movements. De Quervain’s tenosynovitis may be caused by overuse. It also is associated with pregnancy and rheumatoid disease. It is most common in middle-aged women.

Most patients experience pain over the outer part of the wrist. This is worsened by grasping maneuvers of the hand and tilting the hand away from the thumb.
The diagnosis of osteoarthritis of the knee is typically made by a combination of the patient’s history, the findings on physical examination.
Treatment of de Quervain’s tenosynovitis is aimed at relieving the pain caused by irritation and swelling, and allowing the inflammation to subside. Conservative approaches activity modification, splints, or in severe cases a cast, anti-inflammatory medication, and cortisone injections. If symptoms persist, surgery can be considered, and involves releasing the compressive sheath that constricts the tendon.
