A traction splint is defined as:

• A. A device applying longitudinal force to a femur fracture
• B. A device used to immobilize the entire limb
• C. A device to compress soft tissues and control bleeding
• D. A device to immobilize joints above the knee

Answer: (A)

The main idea is that a traction splint is used to apply a longitudinal pull along the femur to help realign and stabilize a fracture. By gently pulling on the leg, the device reduces muscle spasm, decreases pain, and keeps the fracture fragments in better alignment during transport. This is different from simply immobilizing the limb, which doesn’t address the alignment of the broken bone, or from devices that compress soft tissue to control bleeding or immobilize joints above the knee. The key feature that defines a traction splint is the longitudinal force applied along the femur to realign the fracture.
