Which of the following is NOT a type of skin traction?

The correct choice is based on the understanding of the two primary categories of traction used in clinical settings: skin traction and skeletal traction. Skin traction involves the application of a pulling force to the skin and surrounding tissues, which helps alleviate pain and immobilize fractures without the need for invasive procedures.

Buck's traction is a common form of skin traction used primarily for hip fractures or knee injuries, where a pulling force is applied via straps or adhesive devices secured to the skin. Bryant's traction is another type specifically utilized for treating femur fractures in children. Pelvic traction also falls under the skin traction category, as it uses belts or straps placed on the skin to provide traction to the pelvis.

In contrast, skeletal traction involves the insertion of pins or wires into the bone itself to create a direct pull on the skeletal structure. This method allows for more significant weights and is generally used for complex fractures or in situations where more stability is required. Therefore, skeletal traction is distinct from the skin-based options and does not fit into the category of skin traction, making it the correct answer to the question.
