What is the main purpose of a splint?

The main purpose of a splint is to immobilize a part of the body. Immobilization is crucial in the case of fractures, sprains, or other injuries as it helps prevent further movement that could exacerbate the injury or lead to additional damage. By keeping the affected area stable, a splint aids in reducing pain and allows for the natural healing process to begin without interference from movement. This is particularly important following an injury to ensure that bones, joints, and soft tissues can heal appropriately.

While enhancing mobility, promoting blood circulation, and cooling down inflammation are also relevant to injury management in certain contexts, they do not align with the primary function of a splint, which is specifically designed to restrict movement in the injured area.
