A traction splint is a medical device used to stabilize and immobilize broken bones, particularly in the femur (thigh bone). It works by applying a pulling force to the limb, which helps align the bone fragments and reduce pain. Traction splints are commonly used in emergency situations to prevent further injury before a patient reaches a hospital. These splints are typically made of lightweight materials and consist of a long rod with adjustable straps. They are designed to be easy to apply, allowing first responders to provide immediate care. Proper use of a traction splint can significantly improve patient outcomes in cases of severe limb fractures.
