De Quervain's tenosynovitis (DQT) is a painful, stenosing condition of the first dorsal compartment of the wrist, where the and extensor pollicis brevis (EPB) tendons reside . It is primarily characterized by thickening and swelling of the extensor retinaculum, which causes increased friction and restricts the smooth gliding of these tendons. Key Characteristics & Etiology

While often called "inflammation," modern research suggests it may be a degenerative process (tendinosis) rather than a purely inflammatory one.

Most common in women (especially aged 30–50) and frequently associated with postpartum care (lifting infants). Other triggers include repetitive thumb activities like texting, gaming, golfing, or racquet sports.
