The specific indications are: (1) degenerative disc disease (as defined by back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies), (2) pseudoarthrosis, (3) spondylolysis, (4) spinal deformation such as kyphosis and lordosis, (5) fracture, (6) unsuccessful previous attempts at spinal surgery, (7) tumor resection, (8) correction of severe instability and/or deformity when used in addition to a posterior spinal instrumentation system, (9) neoplastic disease, and/or (10) deformity associated with deficient posterior elements, such as laminectomy, spina bifida, or myelomeningocele. ## Device Story The LAURAIN DEWALD Anterior Fixation System is a spinal orthosis consisting of plates, screws, nuts, spacers, and staples. It is used by surgeons in an operating room setting to provide mechanical stabilization of the spine during the development of a solid spinal fusion. Components are selected and locked into configurations tailored to the individual patient's anatomy and pathology. The system acts as an internal fixation device to maintain alignment and stability while bone fusion occurs. It is intended for use in various spinal conditions, including degenerative disc disease, fractures, and deformities. ## Clinical Evidence No clinical data provided; substantial equivalence is based on design and intended use. ## Technological Characteristics System consists of metallic plates, screws, nuts, spacers, and staples. Mechanical fixation device; no energy source or software components. Sterilization method not specified. ## Regulatory Identification A spinal interlaminal fixation orthosis is a device intended to be implanted made of an alloy, such as stainless steel, that consists of various hooks and a posteriorly placed compression or distraction rod. The device is implanted, usually across three adjacent vertebrae, to straighten and immobilize the spine to allow bone grafts to unite and fuse the vertebrae together. The device is used primarily in the treatment of scoliosis (a lateral curvature of the spine), but it also may be used in the treatment of fracture or dislocation of the spine, grades 3 and 4 of spondylolisthesis (a dislocation of the spinal column), and lower back syndrome. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
