DeQuervain’s Tenosynovitis (or tendinitis) is a tendinitis of the abductor tendon and short extensor tendon of the thumb as they pass through the first extensor compartment at the radial side of the wrist. Inflammation and thickening of the tendon produce a size discrepancy such that the tendon no longer glides smoothly through this sheath resulting in pain with thumb motion. In more severe cases actual popping and catching of the tendon may occur. Treatment options include rest, anti-inflammatory medications such as ibuprofen or naproxen, splinting, steroid injections, and operative release of the sheath. Dr. Fremling has been providing operative treatment for DeQuervain’s Tenosynovitis of over 20 years.
