De Quervain’s tendinosis occurs when the tendons around the base of the thumb are irritated or constricted. The word “tendinosis” refers to a swelling of the tendons. 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. 

Anatomy

Two of the main tendons to the thumb pass through a tunnel (or a 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 allows 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.

Causes

De Quervain’s tendinosis may be caused by overuse. It is also associated with pregnancy and rheumatoid disease. It is most common in middle-aged women. If you are experiencing any of these symptoms, we recommend that you contact our office for a diagnosis of the signs that you are having and to begin a treatment plan to help you with the issues you are having. 

Symptoms

  • Pain may be felt over the thumb side of the wrist. As the main symptom, the pain may appear either gradually or suddenly. Pain is felt in the wrist and can travel up the forearm. The pain is usually worse when the hand and thumb are in use. This is especially true when forcefully grasping objects or twisting the wrist.
  • Swelling may be over the thumb side of the wrist. This swelling may accompany a fluid-filled cyst in this region. 
  • A “catching” or “snapping” sensation may be felt when moving the thumb. 
  • Pain and swelling may make it difficult to move the thumb and wrist.
