Abstract: An orthopedic appliance apparatus for treatment of scoliosis has first and second polymer lateral shells, each formed with a curvature so that when connected together they will enclose the central portion of the body of a patient and apply an arcuate bending force to the spine opposite the lateral curvature of the spine. The shells are connected, one side with rivets and the other side with velcro straps which allows the tightening of the brace to fit the patient. Padding is positioned in predetermined positions with the greatest application of force as made against the body. One shell has a plurality of slots formed therein along one edge to allow expansion of the curvature of the shell.
