Summarize this article:

Only move someone if there is imminent danger when a bone is broken during a serious fall or from a car accident. Do not try to realign the bones or move the injured person if he is unable to move on his own. This will avoid further injury to the area.  Do not move anyone with a pelvic or hip fracture; pelvic fractures can cause massive internal bleeding into the pelvic cavity. Instead, call emergency services right away and wait for medical support. However, if a person with this kind of injury absolutely must be transported without emergency medical attention, then place a roll or pillow between the person's legs and secure the legs together. Roll the person onto a board for stabilization by rolling them as one piece. Keep the shoulders, hips and feet lined up and roll them all together while someone slides a board under her hips. The board must reach from the middle of the back to the knees.   Do not move a person with a potential broken back, neck or head. Immobilize her in the position in which you find her and call for emergency help immediately. Do not try to straighten her back or neck. Tell emergency personnel you suspect a broken head, back or neck and why. Moving the person could cause severe long-term damage, including paralysis. Care for all wounds before dealing with a broken bone. If a bone is protruding from the skin, do not touch it or try to place it inside the body. The color of bone is usually gray or light beige, not the white bone you see on Halloween and medical skeletons. If there is severe bleeding, always take care of the bleeding before dealing with the broken bone. Only provide care to the broken bone if emergency medical treatment is not expected immediately. If emergency personnel are expected immediately or you are en route to a hospital, splinting the area can do more harm than good. However, if treatment in a medical facility is not immediately available, you can help to stabilize the bone and relieve the pain using these guidelines.  Splint a broken arm or leg to give it support. Do not try to realign the bone. To make a splint you can use material you have on hand or can find nearby. Look for rigid material to make the splint, such as a board, stick, rolled up newspaper, and so on. If the body part is small enough (like a small toe or finger) it can be taped to the toe or finger next to it to provide stability and splinting.  Pad the splint with clothing, towels, blankets, pillows or anything else that is soft at hand. Extend the padded splint to beyond the joint above and below the break. For instance, if the lower leg is broken, the splint should go above the knee and lower than the ankle. Similarly, breaks on joints should be splinted to both of the bones adjacent to the joint. Secure the splint to the area. You can use a belt, rope, shoelaces, anything that is handy that will keep the splint in place. Be careful when you apply the splint not to cause further injury to the body. Pad the splint well so it doesn’t add pressure to the injured area but only immobilizes it. if the broken bone is arm or hand. This helps support the arm and avoid fatiguing the muscles. Use a piece of cloth that is approximately 40 inches square cut from a pillowcase, bedsheets or any other larger material. Fold it into a triangular piece. Place one end of the sling under the injured arm and over the shoulder while taking the other end over the other shoulder and cradling the arm. Tie the ends behind the neck.

Summary:
Don’t move an injured person as a general rule. Control any bleeding from an accident or injury. Immobilize the area. Make a sling
