An externally-worn orthopaedic device designed to apply traction to the lumbar spine to relieve symptoms of back pain and sciatica. It consists of adjustable components worn superiorly under the rib cage, and inferiorly over the iliac crests, with rods holding the components apart that can be adjusted to apply traction forces by separation. It may include an additional attachable component intended for the treatment of scoliosis. It is intended for use in the home or a clinical setting. This is a reusable device.
