The Jewett type thoraco-lumbo-sacral orthosis has been used in patients with vertebral compression fracture. It provides a three-point pressure system consisting of posteriorly directed forces from the sternal pad and the pubic pad, and an anteriorly directed force from the thoraco-lumbar pad. But it is always recognized that the pubic area is insufficiently fixed by the pubic pad. Therefore it will not do well enough for thoraco-lumbar flexion control. For the purpose of making this better, we developed a rapidly constructable thoraco-lumbar flexion control orthosis. The orthosis has a triangular upright and the location of the pubic pad is transferred to the areas of bilateral anterior superior iliac spines, and we clinically applied our orthosis. Our orthosis has good adjustability, comfortable wearing and excellent thoraco-lumbar flexion control. Taking negative cast model or measurement is not needed for the orthosis.
