A broken bone can become more dangerous if the injured area moves before medical care arrives. Splinting helps stabilize the injury, reduce pain, and lower the chance of damage to blood vessels, nerves, and surrounding tissues. The goal is not to straighten or fix the bone, but to keep the limb as still as possible.
Good emergency preparation helps students respond calmly and safely when an injury happens.
Key Facts
- Call emergency services for a suspected broken bone, especially if there is severe pain, deformity, heavy bleeding, numbness, or the bone is visible.
- Immobilize the joint above and the joint below the suspected fracture whenever possible.
- Splint length should extend past both nearby joints to reduce movement of the broken bone.
- Use padding between the limb and any rigid splint to spread pressure and protect the skin.
- Check circulation, sensation, and movement before and after splinting: color, warmth, pulse, feeling, and ability to wiggle fingers or toes.
- Do not push a bone back into place or force a bent limb straight, because this can worsen internal injury.
Vocabulary
- Splint
- A splint is a rigid or semi-rigid support used to keep an injured body part from moving.
- Fracture
- A fracture is a crack, break, or complete separation in a bone.
- Immobilization
- Immobilization means preventing movement of an injured area to reduce pain and further damage.
- Circulation
- Circulation is the movement of blood through the body, which can be checked by skin color, warmth, pulse, and capillary refill.
- Padding
- Padding is soft material placed around an injury or under a splint to reduce pressure and protect tissues.
Common Mistakes to Avoid
- Trying to straighten the injured limb is wrong because forcing the bone into a new position can damage nerves, blood vessels, and soft tissue.
- Tying cloth strips directly over the suspected fracture is wrong because pressure on the break can increase pain and worsen tissue injury.
- Making the ties too tight is wrong because it can reduce blood flow, causing numbness, swelling, or cold fingers or toes.
- Skipping circulation and sensation checks is wrong because a splint that looks secure may still be cutting off blood flow or pressing on nerves.
Practice Questions
- 1 A student has a suspected forearm fracture. The wrist is 18 cm from the elbow. If the splint must extend 5 cm beyond the wrist and 5 cm beyond the elbow, what minimum splint length is needed?
- 2 You have cloth strips that are each 60 cm long. Each tie around a padded lower leg uses 25 cm, and you need 3 ties. How many strips are needed, and how much total cloth length will be used?
- 3 A splint is applied to a lower leg injury. After tying it, the toes become pale, cold, and numb. Explain what this suggests and what should be done next.
