A splint is a padded support that holds part of an injured arm or leg in the best position for healing. The splint is secured in place by an elastic bandage. The purpose of a splint is to prevent movement and protect a fracture, possible fracture, or torn ligament until the swelling has gone down. When the swelling is gone, an orthopedist can apply a full cast if needed.
Most children who have a splint need it to be replaced by a cast in a few days.
