The VERTE-STACK TM Spinal System is a vertebral body replacement device intended for use in the thoracolumbar spine (T1-L5) to replace a collapsed, damaged, or unstable vertebral body due to turnor or trauma (i.e., fracture). The VERTE-STACK™ Spinal System is to be used with supplemental fixation. Specifically, the VERTE-STACK™ device is to be used with the Medtronic Sofamor Danek ZPLATE II Anterior Fixation System, Titanium DYNALOK™ CLASSIC Spinal System, the VANTAGE™ Anterior Fixation System, Titanium TSRH® Spinal System, Titanium CD HORIZON® Spinal System, the Titanium GDLH® Spinal System, or their successors. Additionally, the VERTE-STACK™ device is intended to be used with bone graft.

Device Description

The VERTE-STACK™ device, is a stackable PEEK spacer, which inserts between vertebral bodies in the anterior thoracic and lumbar spine. The device is intended for vertebral body replacement to aid in the surgical correction and stabilization of the spine. The construct is not intended to be employed as a stand-alone device. The VERTE-STACK™ device is fabricated and manufactured from POLYETHERETHERKETONE (PEEK OPTIMA LT) as described by ASTM F-1579. The tantalum marker used for this product is made to the voluntary standard of ASTM F-560.

The design of the VERTE-STACK™ device includes a variety of stackable components of different sizes and heights. The stackable components are designed to suit the individual patient pathology.

The VERTE-STACK™ device may be used individually, or stacked together in order to accommodate the individual anatomical requirements of the vertebral space created by the corpectomy.

The VERTE-STACK™ Spinal System must be used with additional anterior and/or posterior spinal instrumentation to augment stability.

The purpose of this submission is to include additional components to the VERTE-STACKTM Spinal System.

AI/ML Overview

The provided text describes a medical device, the VERTE-STACK™ Spinal System, and its substantial equivalence to previously cleared devices. It does not contain information about acceptance criteria, device performance, a study to prove acceptance criteria, sample sizes, ground truth establishment, or human-in-the-loop performance. The document is a 510(k) summary for a submission in 2003, which is a regulatory document affirming equivalence, not a detailed technical study report comparing performance against specific metrics.

Therefore, I cannot provide the requested information based on the input text. The information needed to complete the table and answer the study-related questions is not present in the provided document.

Dear Dr. Treharne:

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 forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

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.
