The comfortable brace which has been described applies effective three-point pressure for the correction of spinal scoliosis. It does not unduly restrain the patient. Chest expansion is not restricted. The corrective force is obtained by tightening only one screw which is permanently attached to the brace and which transmits the force to the chest and pelvis by a very powerful leverage through a toggle bar. This brace is most effective in the correction of single flexible curves, but it is also applicable in certain cases of structural double curves which are not fixed. Operative procedure and exercises are not supplanted, but supplemented by this brace.
