A TLSO is a rigid spinal Orthosis that spans the thoracic, lumbar and sacral spine. It is used to provide post-traumatic and post-surgical stabilization. A custom-made, rigid TLSO provides the maximum amount of exterior stabilization to the thoracic and lumbar parts of the spine.
The effective range of stabilization is from T5 – L4. An extension to the head with a cervical superstructure or to the leg with a hip joint and thigh cuff can increase the effective range of the TLSO through the entire length of the spine.
