Össur Formfit Thumb Spica Splint – De Quervain's, CMC Joint & Thumb Stabilizer Brace
The Össur Formfit Thumb Spica Splint is a clinically designed thumb stabilizer brace that immobilizes the thumb and wrist to support healing from De Quervain's tenosynovitis, CMC joint arthritis, Gamekeeper's Thumb, scaphoid injuries, and thumb sprains. Available in Left and Right versions in sizes XS through XL, with a moldable stay system for a customized fit. This is the sized version — for a one-size-fits-most option, see the Formfit Universal Thumb Spica.
Sized vs. Universal — Which should I choose?
- This splint (Sized, Left/Right) — Best when a precise fit is needed, or when the clinician specifies a particular size. Available XS–XL with wrist circumference sizing.
- Universal version — One size fits most, ambidextrous. Faster to dispense in a clinical setting.
