De-Quervain SyndromeDe-Quervian syndrome is a painful condition affecting the tendons on the thumb side of your wrist and the movements of the first finger. When making certain movements, it presents with a strong pain where the thumb joins with the wrist. Lifting and gripping movements become very painful, which requires joining of the thumb and index fingers. The cause of the syndrome is the restricted movement of tendons (abductor pollicis longus and extensor pollicis brevis) in the tunnel, which move the thumb inward and sideward. Some claim that the cause of De Quervain syndrome is use of musical instrument, knitting, and repetitive works such as baby care, resulting in edema of the tendons and their sheath. It is more common in those who mostly use their thumb, and in women.
The first-line therapy for the disease is to use a splint to restrict the movements of the thumb. This therapy is supported by anti-inflammatory medication. It will be helpful to inject corticosteroids into the painful area in cases where no improvements can be achieved. The tunnel in which the tendons lie can be relaxed surgically when these methods fail.
