De Quervain's Release (Cadaver)

Abstract

De Quervain’s release is a surgical procedure performed to curatively treat stenosing extensor tenosynovitis of the first extensor compartment of the wrist, after nonoperative management fails. This procedure involves surgical release of the first dorsal compartment with care taken to fully release the abductor pollicis longus (APL) and extensor pollicis brevis (EPB) tendons from their respective sheaths, while protecting the radial sensory nerve, in order to decompress the extensor tendons. This video outlines the operative technique used by Dr. Asif Ilyas for performing a De Quervain’s release on a cadaveric wrist.
