What is the primary function of a lumbosacral orthosis with steel stays?

The primary function of a lumbosacral orthosis with steel stays is to limit motion and provide stabilization. This type of orthosis is designed to restrict excessive movement in the lumbar and sacral areas of the spine, which can be crucial for individuals recovering from injuries, surgeries, or conditions that affect the stability of the lower back. By limiting motion, the device helps to protect the spine and allows the surrounding muscles and ligaments to heal properly without the added strain of movement.

Steel stays within the design enhance the orthosis's ability to maintain its structural integrity and resist deformation, ensuring continued support. This stabilization not only aids in recovery but can also help prevent further injuries by reducing strain during activities of daily living.

While other options touch upon aspects that may be addressed by a lumbosacral orthosis, they do not represent the primary function of the device. For example, enhancing posture alignment and improving mobility can be secondary benefits, but they are not the main purpose of providing stabilization through limited motion. Similarly, while supporting lordosis may be a part of the design considerations, it is not the core functionality of the orthosis with steel stays.
