What type of splint is appropriate for a closed long-bone fracture?

• A. A soft wrap
• B. A foam pad only
• C. A rigid splint immobilizing the limb above and below the injury with padding
• D. A vertical split thread

Answer: (C)

For a closed long-bone fracture, the aim is to stop movement at the fracture site by immobilizing the limb with a rigid splint that covers the bone above and below the injury, with padding to protect the skin and soft tissues. This approach keeps the bone aligned, reduces pain, and helps preserve circulation and nerve function during transport. A soft wrap or padding alone doesn’t provide the necessary stability and can allow movement that worsens the injury or causes tissue damage. A rigid splint that extends past the joints above and below, with padding, offers the appropriate immobilization. A method like a vertical split thread isn’t a recognized or reliable way to immobilize a long-bone fracture in the field.
