More Information

  • Directions For Use
  • - Select the correct size.
    - To fit the spring, slide splint onto finger so the proximal pad rests over the volar aspect of the metacarpal head and the distal pad rests at the distal interphalangeal joint (DIP).
    - To adjust spring tension, there are two options:
    - To increase the force of extension, spread the volar pads apart before placing on the finger.
    - To decrease the force of extension, pinch the volar pads together before placing on the finger.
  • Care Instructions
    - Splint can be cleaned by hand washing with a nonabrasive detergent.
    - Air dry before wearing.
