Halo pelvic traction appliance for spinal deformities

Abstract The halo pelvic traction appliance, which has been used extensively for the correction of kyphotic and scoliotic spinal deformities, is described in detail. The appliance has been made more versatile to accommodate all shapes of spinal and pelvic deformities. Remarkable results have been achieved by this highly efficient controlled form of distraction which is carefully prescribed under medical supervision. Specifications of the appliance are given to suit a complete range of sizes and weights of patients. Also is included a novel method of measuring the applied tensile distracting force between the skull and pelvis.
