Intended Use

The ZPLATE-ATL™ Anterior Fixation System is intended for screw/bolt fixation/ attachment 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: - Degenerative disc disease (as defined by back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies). - Pseudoarthrosis. - Spondylolysis. - Spondylolisthesis. - Fracture. - Neoplastic disease. - Unsuccessful previous fusion surgery. - Lordotic deformities of the spine. - Idiopathic thoracolumbar or lumbar scoliosis - Deformity (i.e., scoliosis, lordosis, and/or kyphosis) associated with deficient posterior elements such as that resulting from laminectomy, spina bifida, or myelomenigocele. - Neuromuscular deformity (i.e., scoliosis, lordosis, and / or kyphosis) associated with pelvic obliquity.

Device Story

ZPLATE-ATL™ Anterior Spinal Fixation System provides temporary spinal stabilization to facilitate fusion. System comprises various plates, bolts, screws, and nuts. Surgeon selects and configures components intraoperatively for individual patient anatomy. Device is implanted via anterior/anterolateral approach to T1-L5 vertebral bodies; unilateral placement required to avoid aorta and nerve roots. Provides mechanical support during bone healing. Benefits include stabilization of spinal segments in patients with degenerative, traumatic, or deformity-related conditions.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

System consists of metallic plates, bolts, screws, and nuts. Components are modular, allowing for custom construct configurations. Designed for unilateral anterolateral fixation. No specific materials or ASTM standards cited in the provided text.

Indications for Use

Indicated for patients requiring spinal stabilization from T1 to L5 for degenerative disc disease, pseudoarthrosis, spondylolysis, spondylolisthesis, fractures, neoplastic disease, failed fusion, lordotic deformities, idiopathic scoliosis, deformities due to deficient posterior elements, or neuromuscular deformity. Contraindicated for posterior element (pedicle) attachment in cervical, thoracic, or lumbar spine.

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.

#### IV. Indications

The ZPLATE-ATL™ Anterior Fixation System is intended for screw/bolt fixation/attachment 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:

- Degenerative disc disease (as defined 1. by back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies).
- Pseudoarthrosis. 2.
- 3. Spondylolysis.
- Spondylolisthesis. 4.
- న. Fracture.
- Neoplastic disease. 6.
- 7. Unsuccessful previous fusion surgery.

Dear Dr. Treharne:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (OS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
