This invention is an orthosis for external application to the wrist for treatment of carpal tunnel syndrome which applies sumultaneous yet independent bilateral parallel midline compression along with distal ends of the radius, the ulna, the lateral, and the medial wall of the carpal bones. The orthoses relaxes the flexor retinaculum (transverse and volar carpal ligaments), reverses anterior to posterior prolapse of the carpal tunnel, reduces stress on the median neerve, ligaments, and bursa traversing the wrist. The device is constructed to allow full and unrestricted movement of the wrist, hand, and fingers. The device utilizes a flexible substrate (34) to which are attached releasable compression elements (42, 44) for positioning at the distal end of the radius, and ulna at the lateral walls of the carpal tunnel. A cinching loop (37), and a releasable closure element (38, 48) are integrally constructed into the substrate material for securing the device to the wrist such that the compression and torsion act on the element, which are transferred to the radius and ulna ends. The device is constructed so as to be worn on either the right or left wrist and accommodates either large or small wrist circumferences.
