Stabilizing the injured limb to prevent movement is key. When a limb is injured, any movement can make the damage worse—bones can shift, soft tissues and vessels can tear, and pain increases from muscle guarding. A splint holds the area in a neutral position, preventing further injury and making transport safer during prolonged care. This stabilization also reduces pain because it limits nerve and muscle irritation caused by movement. In a field or extended-care setting, keeping the limb immobilized until definitive treatment is available minimizes complications from ongoing movement and supports safer evacuation. When you apply a splint, immobilize the joints above and below if possible, pad for comfort, and secure without cutting off circulation; check distal sensation and color before and after. Do not remove the splint during evacuation. Elevating the limb can help with swelling and pain, but the main purpose of splinting is to reduce movement and pain. Tourniquets are for life-threatening bleeding, not general splinting.
