In medicine, there are two types of orthopedic traction: skin traction and skeletal traction. Modern techniques continue to be developed and improved, but some of the approaches still used are: Bryant's traction, Buck's traction (hips), Dunlop's traction (kids), Russell's traction and the Milwaukee brace.
