Broken bones (fractures) are usually not life-threatening. A fracture may not be visible to you through the skin. Symptoms include intense pain, swelling, increased pain when trying to move the injured area, or bleeding. A broken bone always requires medical attention.
Call out for someone to get help, or call 911 yourself. Do not move or straighten the broken bone. Splinting is not necessary unless the person needs to be moved without assistance from ambulance personnel or unless the fracture has blocked blood supply to the limb. If the fracture site is deformed and the skin beyond the site of the fracture is cold, pale, and blue, pull gently lengthwise on the limb to straighten the fracture and then splint the limb.
