What is the primary purpose of a TLSO?

The primary purpose of a thoraco-lumbo-sacral orthosis (TLSO) is to control thoracic and lumbar motion. TLSOs are designed to limit the motion of the spine in all three planes—flexion, extension, and rotation—providing stability and support. This is particularly important in managing conditions such as scoliosis, postoperative support, and osteoporosis-related fractures. By controlling motion, the TLSO helps alleviate pain and aids in the healing process by limiting stress on the spine, which is crucial for patients recovering from spinal injuries or surgeries.

While complete immobilization of the thoracic spine might be a consideration in certain cases, the TLSO is generally designed to allow for some degree of mobility while still providing the necessary support. Decoration for patient comfort is not relevant to the functional objectives of the device, and while enhancing normal spinal posture is a beneficial outcome, it is not the primary focus of a TLSO's design. Instead, controlling motion is essential for effective management of various spinal conditions and improving patient outcomes.
