The rigid rest orthosis EPITACT® is recommended for nighttime use, or whenever you are in a resting position (with limited hand movements). Regular use of this orthosis helps relieve joint pain at the base of the thumb, and thanks to its pre-molded anatomical reinforcements, it limits the progression of rhizarthrosis. Lightweight and ultra-thin, you won't even know you're wearing it! The orthosis is hand washable at a temperature not exceeding 3°C, with water and soap. When used and handled correctly, it can last for several months. Available in 3 sizes and in two versions, for the right or left hand. Medical Device.
