De Quervain tenosynovitis is characterised by pain localised to the wrist joint, specifically near the base of the thumb. The tendons responsible for extending and abducting the thumb experience constriction in a tight tunnel, leading to progressive inflammation caused by friction and repetitive tendon gliding.
The exact cause of de Quervain tenosynovitis has not been established. However, inflammation of the tendons has been associated with repetitive trauma or overuse of the thumb and wrist in daily activities, such as:
​Most patients experience pain at the side of the wrist, particularly near the base of the thumb. It usually occurs after recent increased activities involving the wrist and hand. It begins as an aching sensation and progresses to a point when any movement of the wrist or thumb produces sharp pain in the affected area. Swelling in that area of the wrist may occur intermittently. Some individuals may experience difficulties with activities that involve pinching, lifting the thumb or turning the wrist (e.g., wringing towel, cutting with scissors and stapling)
Doctors usually initiate non-surgical treatment methods, which may involve wearing a splint or taking oral anti-inflammatory medication. In some cases, an injection of steroids may also be administered.
