The Modabber Thumb Orthosis is made from 1/8" neoprene that provides compression. The brace fits left or right hand to reduce inventory. It has an aluminum stay and steel spiral stay that are both interchangeable and removable. The orthosis is ideal for treating basal joint arthritis, throttle thumb and thumb tendinitis. A patented elasticized patient assist tap makes one-handed application easy. Taping above the stay allows trimming for freedom of the IP joint.
