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.

Warning: This device is not approved for screw attachment to the posterior elements (pedicle) of the cervical, thoracic, or lumbar spine.

Device Description

The ZPLATE-ATL™ Anterior Spinal Fixation System consists of a variety of shapes and sizes of plates, bolts, screws and nuts, as well as ancillary products and instrument sets. The components can be locked into a variety of configurations, with each construct tailor-made for the individual case.

AI/ML Overview

The provided text is a 510(k) summary for the ZPLATE-ATL™ Anterior Spinal Fixation System, which describes a medical device, not an AI or software device. Therefore, the questions related to acceptance criteria, study design, ground truth, and expert evaluation for AI performance are not applicable to this document.

The document focuses on:

Product Description: "The ZPLATE-ATL™ Anterior Spinal Fixation System consists of a variety of shapes and sizes of plates, bolts, screws and nuts, as well as ancillary products and instrument sets. The components can be locked into a variety of configurations, with each construct tailor-made for the individual case."
Indications for Use: Listing specific spinal conditions (degenerative disc disease, pseudoarthrosis, spondylolysis, spondylolisthesis, fracture, neoplastic disease, unsuccessful previous fusion surgery, lordotic deformities, idiopathic thoracolumbar or lumbar scoliosis, deformity with deficient posterior elements, neuromuscular deformity with pelvic obliquity) for which the device can be used for "screw/bolt fixation/attachment to the anterolateral intervertebral bodies from T1 to L5 only."
Substantial Equivalence: Stating that "Documentation was provided which demonstrated the ZPLATE-ATL™ Anterior Spinal Fixation System to be substantially equivalent to itself." This implies it's either a new version of an already cleared device or a direct claim of equivalence to a predicate without listing a different predicate upfront. The FDA letter confirms the FDA's finding of substantial equivalence to "devices marketed in interstate commerce prior to May 28, 1976."

Since this is a physical medical device and not an AI/software device, the questions regarding acceptance criteria and study design for AI evaluation cannot be answered from the provided text.

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.

Regulation Number and Section

§ 888.3060 Spinal intervertebral body fixation orthosis.

(a)
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.(b)
Classification. Class II.
