The splint for the entire leg is a portable splint that is used to immobilize fractures that may occur to the leg of an accident victim. The splint includes two parts that are connectable when the splint is applied to the leg. An upper part functions to immobilize the femur and stabilize the hip. A lower part immobilizes the tibia and/or fibula and stabilizes the knee and foot. Straps are employed to secure the splint to the leg.
