The Double-reverse Traction Fracture Reducer conforms to the mechanical axis and biomechanical properties of limbs. The tractive force is consistent with the direction of muscle fibers, which conforms to the mechanical and biomechanical properties, that is, homeopathic traction. It means that mechanical methods are adopted to pull the distal bone fragment so that the direction of force becomes two opposite directions. Quick reduction can be achieved under large tractive force, which conforms to the axis and biomechanical properties of lower limbs. The product can also be used for fractures over two weeks. Design of different angles of the top-levering device makes it possible to conduct the top-levering, pulling-up, compressing and other reduction operations, easily achieving the closed reduction of the fracture.
