The Abductor Pollcis Longus (APL) and Extensor Pollcis Brevis (EPB) are muscles that start in the forearm and attach at the base of the thumb. As they pass the wrist, they go under a tendon sheath (a band of soft tissue designed to keep the tendons in place) to ensure that when you flex your wrist, the tendons don't go lax/droop. These muscles are responsible for the movement of the thumb away from the index finger, as well as important in tasks such as letting go of an item that was in grip.
With It's patent pending design, the new Ryno Lacer II provides equal tension across all laces offering supreme comfort, ease of application and superior immobilization of the wrist and thumb. New softer proprietary felt liner contains polypropylene and wicks moisture away from the skin. Memory foam padding in palm and around base of thumb enhances comfort and support.
The aluminum stays incorporated in the ManuLoc Rhizo orthosis provide secure support for the wrist and thumb. These stays are already anatomically contoured, but they can also be individually adjusted by an orthotist for optimal support. Although immobilization of the joint is paramount at the start of the treatment, it is also important to gradually exercise the muscles to ensure long-term regeneration. The thumb support can be removed on this splint as well.
