## Indications for use
The XANTUS Anterior Lateral Supplemental Fixation System is intended for screwholt fixatiodattachment to the anterolateral intervertebral bodies from T1 to L5 only. This system is to be used only on one side and placed in such a manner as to be as far away from blood vessels such as the aorta and nerve roots as possible. When properly used, this system will provide temporary stabilization until a solid spinal fusion develops. Specific indications include: 1. Degenerative Disc Disease (DDD as defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies). 2. Pseudoarthrosis . 3. Spondylolysis. 4. Spondylolisthesis. 5. Fracture. 6. Neoplastic disease. 7. Unsuccessful previous hsion surgery. 8. Lordotic deformities of the spine. 9. Idiopathic thoracolumbar or lumbar scoliosis. 10. Deformity (i.e., scoliosis, lordosis, and/or kyphosis) associated with deficient posterior elements such as that resulting from laminectomy, spina bifida, or myelomenigocele. 11. Neuromuscular deformity (i.e., scoliosis, lordosis, and/or kyphosis) associated with pelvic obliquity.
