[VIDEO] Ultrasound-guided infiltration of De Quervain's tenosynovitis
- 11/10/2025
De Quervain's tenosynovitis is an inflammatory condition affecting the tendons at the base of the thumb in the wrist (Abductor Pollicis Longus [AL] and Extensor Pollicis Brevis [EC], specifically in the first extensor compartment). The affected tendons connect the thumb muscles to the carpal bones (wrist). Inflammation of these tendons can cause pain, swelling, and difficulty moving the thumb and wrist. Ultrasound-guided injection of local anesthetic and corticosteroids is a valid therapeutic option to relieve pain and inflammation.
