What is Dequervain’s Tendinitis

Dr. Badia Explains

De Quervain’s tenosynovitis, also known simply as De Quervain’s tendinitis or De Quervain’s syndrome, is a painful condition that affects the tendons in the wrist and thumb. It primarily involves two tendons, the abductor pollicis longus and the extensor pollicis brevis, which are responsible for moving the thumb away from the palm and extending it.

Here’s an explanation of De Quervain’s tendinitis:

Causes: This condition typically arises due to repetitive hand and wrist movements, often associated with activities that require gripping, pinching, or twisting motions. Overuse of these tendons can lead to irritation, inflammation, and thickening of the tendons’ protective sheaths (synovial sheaths), causing pain and discomfort.
