Intended Use

The NuVasive Lateral Plate System is indicated for use via the lateral or anterolateral surgical approach above the bifurcation of the great vessels in the treatment of thoracic and thoracolumbar (T1-L5) spine instability or via the anterior surgical approach, below the bifurcation of the great vessels in the treatment of lumbar and lumborsacral (L1-S1) spine instability as a result of fracture (including dislocation and subluxation), tumor, degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies), scoliosis, kyphosis, lordosis, spinal stenosis, or a failed previous spine surgery.

Device Story

The NuVasive Lateral Plate System is a spinal fixation orthosis consisting of plates, screws, bolts, and locking nuts. It is used by surgeons to provide rigid fixation and stabilization of the spine. The components are implanted via lateral, anterolateral, or anterior surgical approaches depending on the spinal level. By rigidly locking the implant components to the patient's anatomy, the system addresses spinal instability, potentially reducing pain and correcting deformities associated with the specified pathologies. The device is intended for use in a clinical/surgical setting.

Clinical Evidence

No clinical data. Bench testing only.

Technological Characteristics

Spinal intervertebral body fixation orthosis consisting of plates, screws, bolts, and locking nuts. Metallic construction. Rigid locking mechanism. Class II device under 21 CFR 888.3060.

Indications for Use

Indicated for patients requiring stabilization of the thoracic, thoracolumbar, lumbar, or lumbosacral spine (T1-S1) due to instability caused by fracture, tumor, degenerative disc disease, scoliosis, kyphosis, lordosis, spinal stenosis, or failed previous surgery.

Regulatory Classification

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.

Dear Ms. Cousin:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set
