De Quervain’s Tenosynovitis is an inflammation of the tendon sheath of two thumb tendons: the extensor pollicis brevis and abductor pollicis longus. It typically presents with chronic and intense wrist pain during thumb extension and abduction, often radiating to the forearm, making daily activities difficult.

The decision for surgery is made during an orthopedic consultation. A patient interview identifies symptoms and their triggers, followed by a physical examination to assess tenderness, thumb and wrist mobility limitations, and perform the Finkelstein test.

De Quervain’s surgery aims to relieve pain and restore hand function by decompressing the tendons near the wrist. After preparing the surgical site and administering local anesthesia, the surgeon makes a small incision near the wrist and cuts the constricted pulley and tendon sheath to release the compressed thumb tendons. The procedure lasts 20–30 minutes and does not require hospitalization.

Immediately after surgery, the hand may be slightly swollen and tender. Elevating the hand, e.g., in a sling, is recommended to reduce swelling. Full recovery typically takes 4–6 weeks. Postoperative rehabilitation is advised to improve thumb and wrist range of motion.
