Which type of TLSO aims specifically to prevent flexion in the thoracic spine?

The type of TLSO (thoraco-lumbo-sacral orthosis) that aims specifically to prevent flexion in the thoracic spine is the CASH TLSO (Cruciform Anterior Stabilizing Hyperextension TLSO). This orthotic device is designed to provide support for patients with conditions such as thoracic kyphosis, vertebral fractures, or post-surgical stabilization.

The CASH TLSO utilizes a unique design that creates a mechanical advantage to promote hyperextension by applying a force anteriorly at the sternum and sacrum, effectively restricting flexion movement in the thoracic area. The orthosis features a rigid frame along with adjustable components that allow healthcare providers to customize the fit and promote optimal spinal alignment in the thoracic region.

Other types of TLSOs, such as the Boston brace, Jewett TLSO, and Taylor orthosis, serve different purposes or mechanical functions. For instance, while the Jewett TLSO also prevents flexion, it primarily focuses on providing a specific hyperextension force, which might not be as universally effective in all thoracic flexion scenarios as the CASH TLSO. Similarly, the Taylor orthosis is more focused on limiting motion in both flexion and extension without the same targeted mechanism as the CASH TLS
