De Quervain's Tenosynovitis Syndrome

One of the most common kinds of tendon inflammation, De Quervain's tenosynovitis syndrome causes pain at the base of the thumb when moving the thumb away from the hand. The inflammation affects the fluid-filled sheath, or synovium, that surrounds the tendon. This disorder causes difficulty in gripping or hand-twisting motions. Like carpal tunnel syndrome or tennis elbow, this injury usually results from overuse.

Symptoms

• Some people with De Quervain's tenosynovitis syndrome also experience pain and swelling on the wrist near the thumb. Pain may increase when moving either the thumb or the wrist, and people might feel pain when pressure is applied there.

Gender and Age

• Women are more likely to have De Quervain's tenosynovitis syndrome than men are, and people between 30 and 50 years old are more commonly afflicted.

Considerations

• Pregnant women are more likely to get the syndrome, as are people with diabetes or rheumatoid arthritis.

Treatment

• Treatment usually involves splinting the thumb and wrist to prevent movement. Doctors may prescribe anti-inflammatory medication to reduce pain.

Surgery

• Most people respond well to splinting and medication, but sometimes surgery is necessary to release the tendons.
