Which orthosis can be categorized as a posterior shell TLSO?

The posterior shell TLSO, or thoracolumbosacral orthosis, is designed to provide support and immobilization to the thoracic and lumbar spine. The Spinomed orthosis is specifically characterized by its posterior shell design, which helps to stabilize the spine while allowing for some mobility. It is intended primarily for patients with osteoporosis, back pain, or to aid in spinal alignment and posture correction.

The distinguishing feature of the Spinomed is its posterior shell structure, which encompasses the back and effectively transfers pressure and support to the spine while permitting anterior flexion. This design is critical in managing conditions that involve muscle weakness or spinal misalignment.

In contrast, the CTO (Cervical Thoracic Orthosis) serves a different anatomical focus by incorporating cervical support in addition to thoracic stabilization. The CASH TLSO (Cruciform Anterior Spinal Hyperextension TLSO) includes an anterior component and is designed primarily for managing conditions like compression fractures. The Knight-Taylor orthosis combines features of both the TLSO and a cervical structure but does not strictly fit the posterior shell classification.
