It is an orthosis that, without immobilising, keeps the thumb in a resting position. Thanks to its unique patented pattern, it is forgotten while helping to relieve joint pain at the base of the thumb (rhizarthrosis) and limiting traumatic micromovements. Thanks to the Epitheliumflex® system, it keeps the thumb in a resting position and has an analgesic effect by maintaining local heat. Used daily, it maintains the full functionality of the hand. Designed to adapt to the demands of everyday life, this orthosis does not incorporate any aggressive "scratches" that could damage clothing. Slim and discreet, it allows watches and jewellery to continue to be worn. Model for the left hand.
