What is De Quervain’s tenosynovitis?
De Quervain’s disease is a painful wrist condition that affects the tendons on the thumb side of the wrist (the radial side). Symptoms may include pain, or tenderness when moving the thumb, rotating the wrist, gripping something, or forming a fist. Pain may spread to the thumb or forearm. Some people have swelling on the radial side of the wrist, or difficulty holding objects.
Other names of this syndrome include: De Quervains tenosynovitis, De Quervain’s syndrome, De Quervain’s tendonitis or wrist tendonitis.
What causes De Quervain’s tenosynovitis?
Overuse of the wrist and hand is one of the principal culprits. Two main tendons — the extensor pollicis brevis and abductor pollicis longus tendons attach the thumb to the forearm, reaching through the fibrous sheath at the wrist.
