Ossur Formfit Universal Thumb Spica Splint – De Quervain's, CMC Joint & Thumb Stabilizer Brace
The Ossur Formfit Universal Thumb Spica Splint is a clinically designed thumb spica brace that immobilizes and protects the thumb and wrist — available in a convenient universal fit that works on either hand without needing to choose a specific size. Whether your clinician recommended a De Quervain's splint, a CMC joint splint, or a wrist and thumb brace, the Formfit Universal delivers trusted Ossur quality in a simplified, one-size-fits-most design.
Universal vs. Sized — Which should I choose?
The Universal version fits most adult wrists without precise measurement. If your clinician has measured your wrist and prescribed a specific size (XS–XL), the sized Formfit Thumb Spica may provide a more precise fit.
Both versions are available in Left and Right. The Universal also comes in a Pediatric option and an X-Large for larger hands.
