Supreme PatientFORM 8"Thumb helps treat thumb injuries by holding the thumb securely in place. This particular brace includes all of the same features as the Supreme Wrist Brace, but as the brace immobilizes the wrist, it also immobilizes the thumb. Dual stabilizers restrict wrist movement while permitting full finger function, adjustable straps and five sizes ensure personalized fit, and a comfortable contoured shape and breathable fabric ensure comfort. It is ideal when MP and CMC joint immobilization is desired. The contoured design at the palmar crease allows full finger function. Removable palmar and thumb stays are easily adjusted for custom fit. Loop and lock closure included for easy adjustment. 8" length.
