When properly used, this system will help provide temporary stabilization until a solid spinal fusion develops. Specific indications include: 1) Degenerative disc disease (as defined by 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 fusion 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; and/or 11) Neuromuscular deformity (i.e., scoliosis, and / or kyphosis) associated with pelvic obliquity. ## Device Story PYRAMID™ ANTERIOR PLATE Fixation System is a supplemental spinal fixation construct; consists of titanium alloy plates and screws of various sizes/shapes; used to provide temporary stabilization until solid spinal fusion occurs. Implanted anteriorly at lumbosacral level by surgeons; configurations are tailor-made for individual patient cases. System provides mechanical support to the spine; benefits patient by maintaining stability during fusion process. No software or algorithmic components. ## Clinical Evidence Bench testing only. No clinical data provided. ## Technological Characteristics Construct consists of plates and screws made of titanium alloy (Ti-6Al-4V) per ASTM F136 or ISO 5832-3. Mechanical fixation system; modular design for patient-specific configurations. Stainless steel and titanium components are incompatible. ## Regulatory Identification A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions. ## Predicate Devices - Sofamor Danek ZPLATE-ATL™ Anterior Fixation System ([K922543](/device/K922543.md)) - BUTTERFLY™ PLATE Fixation System ([K010632](/device/K010632.md)) ## Reference Devices - BONE GRAFT WASHER ([K994122](/device/K994122.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
