SplintBox Volar Slab Splint (VSS) Instructions

1. Open the SplintBox VSS, unfold the plastic liner, remove and set items aside.

2. Fold the plastic liner over the edges of the box in order to create a dipping reservoir for the plaster. Fill the box up with warm water.

3. Wrap hand and forearm with the cotton rolls. Leave the thumb free. If you are immobilizing only the wrist, the cotton and plaster should stop short of the metacarpal heads to allow active range of motion of the fingers. If you are immobilizing the finger(s), the cotton and plaster should extend to the tips of the fingers. You should aim to have >50% overlap or enough padding with the cotton so that the skin is protected from the plaster. Make sure to pad pressure points (ulnar border) with extra cotton and avoid wrinkles to prevent potential pressure sores or ulcers.

4. If needed, rip the pre-fabricated plaster slab to desired length.

5. Submerge the plaster slab in the dipping reservoir. Wring it out and slide between your index and long finger so that the holes are no longer visible in the plaster slab. Place on the volar aspect of the wrist and hand. Make sure the plaster is off skin. Provisionally secure the plaster with cotton rolls.

6. Wrap with the elastic bandage, starting distally and moving proximally. Mold as needed. Allow the plaster to fully harden.


7. Place solidifier in the dipping reservoir and then pull the plastic liner out, tie-up, and dispose. Break down the dipping reservoir box and recycle.
