This document provides guidance on splinting fractures and injuries. It describes splints as devices used to immobilize fractured bones or injured joints prior to medical treatment. The purposes of splinting are to immobilize the injured area, prevent further injury from bone fragments, reduce pain, and manage sprains and strains. General rules for splinting include using padding to support the injured area without interfering with circulation. Improvised materials like wood, cardboard or the body itself can be used to splint fractures until medical help arrives. The document provides specific guidance on splinting different areas, such as the upper arm, elbow, forearm, and lower extremities.
