Intended Use
When intended to promote fusion of the cervical spine and the thoracic spine, (CI-T3), the VERTEX® Reconstruction System is indicated for the following: DDD (neck pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), spondylolisthesis, spinal stenosis, fracture, dislocation, failed previous fusion and/or tumors. The hooks and rods are also intended to provide stabilization to promote fusion following reduction of fracture/dislocation or trauma in the cervical/upper thoracic (C1-T3) spine. The use of screws (3.5mm, 4.0mm and 4.5mm cancellous and 4.0mm cortical) is limited to placement in T1-T3 in treating thoracic conditions only. The screws are not intended to be placed in the cervical spine. Titanium ATLAS™ Cable System to be used with the VERTEX® Reconstruction System allows for cable attachment to the posterior cervical or thoracic spine.
Device Description
The VERTEX® Reconstruction System is a posterior system, which consists of a variety of shapes and sizes of rods, hooks, screws, multi-axial screws, and connecting components, which can be rigidly locked to the rod in a variety of configurations, with each construct being tailormade for the individual case. Titanium ATLAS™ cable may be used with this system at the surgeon's discretion. The VERTEX® Reconstruction System is fabricated from medical grade titanium alloy. The VERTEX® Reconstruction System also includes a retaining ring for the multi-axial screw made of Shape Memory Alloy (Nitinol – NiTi). Shape Memory Alloy is compatible with titanium or titanium alloy implants only. Do not use with stainless steel. The purpose of this submission was to add modified setscrews to the existing system.
More Information

No
The document describes a mechanical spinal reconstruction system and does not mention any software, algorithms, or AI/ML capabilities.

Yes
The device is described as a "Reconstruction System" and its stated "Intended Use / Indications for Use" are to "promote fusion of the cervical spine and the thoracic spine" for various medical conditions, including DDD, spondylolisthesis, spinal stenosis, fracture, and tumors. These are therapeutic actions aimed at treating medical conditions.

No
The document describes a surgical implant system intended for spinal fusion and stabilization, not for diagnosing medical conditions.

No

The device description explicitly details various hardware components like rods, hooks, screws, and cables, all fabricated from medical-grade titanium alloy and Shape Memory Alloy. This indicates it is a physical implant system, not a software-only device.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly describes a surgical implant system for stabilizing the cervical and thoracic spine to promote fusion. This is a therapeutic intervention performed in vivo (within the body).
  • Device Description: The device is described as a system of rods, hooks, screws, and connecting components made of titanium alloy, designed for surgical implantation.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or compatibility testing.

Therefore, the VERTEX® Reconstruction System is a surgical implant device, not an In Vitro Diagnostic device.

§ 888.3050 Spinal interlaminal fixation orthosis.

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

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.
