Splinting is used to immobilize injured extremities to reduce pain and prevent further damage. There are different types of splints that can be used depending on the injury. Guidelines for splinting include covering wounds, splinting above and below the injury, elevating the extremity, applying ice, and seeking medical help for certain symptoms. Slings are used to support injured arms, using triangular bandages or improvised materials. Specific splinting techniques are described for different body parts like the shoulder, humerus, elbow, wrist, pelvis, femur, knee, lower leg, ankle and foot.
