Traction involves applying a pulling force to part of the body while countertraction pulls in the opposite direction. It is used to provide alignment, reduce muscle spasms, prevent deformities, provide immobilization, and increase space between opposing surfaces. There are several types of traction including skin, skeletal, and manual traction. Skin traction applies force to the skin and soft tissues using materials like bandages and tapes. Skeletal traction applies direct force to bones using pins or wires inserted through the bone. Nursing care for patients in traction focuses on maintaining proper positioning and traction, preventing skin breakdown, and assessing neurovascular status.
