Recognising the Signs of a Fracture
It can be difficult for a layperson to distinguish between a fracture, a sprain, or a dislocation, but some key signs suggest a broken bone. If in doubt, it is always safest to treat the injury as a fracture. Look for severe pain, especially when a person tries
to move or put weight on the limb. Swelling, bruising, and visible deformity—like a limb appearing bent at an unnatural angle—are strong indicators. Sometimes, a snapping or grinding sound may have been heard at the time of the injury. The person may also be unable to move the affected area at all. In severe cases, especially with large bones like the thigh or pelvis, the person might show signs of shock, such as feeling faint, nauseous, or having pale, clammy skin.
The Golden Rule: Do Not Try to Realign
The single most important rule in fracture first aid is to never try to straighten a deformed limb or push a bone back into place. While it might seem helpful, attempting to realign a fracture can cause catastrophic damage. The sharp ends of broken bones can tear nerves, shred blood vessels, and damage surrounding muscles and tissues, turning a simple, closed fracture into a complex injury. If the bone has broken through the skin (an open fracture), trying to push it back in can introduce dirt and bacteria deep into the wound, leading to a serious infection. Leave alignment to medical professionals, who are trained to perform this in a controlled environment, often with the help of imaging like X-rays. Your primary job is to prevent any further harm.
What to Do Instead: Immobilise the Injury
The goal of first aid is not to set the bone, but to keep it still. This is called immobilisation. Keeping the injured part from moving reduces pain and prevents the broken bone ends from causing more damage. Encourage the person to stay as still as possible and reassure them that help is on its way. You can support the limb in the position you found it using cushions, pillows, or rolled-up jackets to prop it up and prevent movement. If you have been trained, you can apply a splint. A makeshift splint can be created from any firm object, like a rolled-up magazine, a piece of board, or even a sturdy stick. The splint should be long enough to extend past the joints above and below the suspected fracture. Pad it well with cloth and tie it securely, but not so tightly that it cuts off circulation.
Managing Other Immediate Concerns
While immobilisation is key, there are other important steps. If there is bleeding, especially from an open fracture, apply pressure to the wound with a clean cloth or sterile bandage. Crucially, apply pressure around the wound, not directly on top of any protruding bone. To manage pain and swelling for a closed fracture, you can apply a cold pack or a bag of frozen vegetables wrapped in a thin towel for 15-20 minutes. Never apply ice directly to the skin, as it can cause burns. Also, remove any rings, watches, or tight jewellery from the injured limb as soon as possible, as swelling can make them difficult to remove later and restrict blood flow.
When to Call for an Ambulance Immediately
While any suspected fracture needs medical attention, certain situations are medical emergencies that require an immediate call for an ambulance. Call for emergency help if you suspect a fracture in the head, neck, or back. A fracture of a large bone like the thigh (femur) or pelvis is also an emergency, as it can lead to severe internal bleeding and shock. If a bone is sticking out of the skin (an open fracture), there is heavy bleeding, or the limb below the injury is numb, pale, or cold, these are all signs that require urgent professional care. Do not give the injured person anything to eat or drink, as they may require surgery.
