When required, the plaster should be split along the entire length.
Once the cast is hardened, mark it, then split using an oscillating saw, a hand saw, or a sharp plaster knife (1).
Take great care to avoid injury to the underlying skin.
Widen the split with a cast spreader. Then divide the underlying padding with scissors (2) and remove the protective strip to expose the skin.
Apply a crêpe bandage to protect the split cast.
When the swelling has subsided (after 5-7 days), complete the cast with a single POP bandage.
