Skin traction is a technique commonly used in orthopedic nursing to stabilize and align fractured bones without the need for invasive surgery. It involves attaching adhesive straps or wraps to the skin around the fractured area and applying a pulling force to maintain proper alignment.

a. Skin traction does not involve the application of a cast. It is a temporary and non-invasive method used to stabilize a fracture before further treatment is provided. 

b. Skin traction is not used to reduce dislocated joints. It is specifically used for fractures. 

d. Skin traction is not a surgical procedure but rather a non-surgical intervention used in conjunction with other treatments.
