The IP is a novel approach to the preoperative treatment of severe spinal deformities, particularly in younger patients. Traditionally, halo gravity traction involves the application of a halo device, which requires hospital admission and fixation in the cranium. However, some patients, namely children, may face challenges with anesthesia or have families who prefer noninvasive treatment options. The IP offers a solution by enabling families to apply traction therapy at home without the need for cranial fixation. The device comprises a torso vest with shoulder straps and an optional head support attachment for children without head control. By securing the patient to a frame, gravity traction is applied to the torso, effectively addressing spinal deformities. Its noninvasive nature eliminates the risks associated with anesthesia and cranial fixation, and it offers the flexibility of home-based treatment, reducing the need for hospitalization and improving patient comfort.
