Intended Use
The Nexus Anterior Cervical Plate System is intended for anterior fixation to the cervical spine. The specific clinical indications include: degenerative disc disease (DDD) (defined as neck pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), spondylolisthesis, trauma (i.e., fracture or dislocation), spinal stenosis, deformities or curvatures (i.e., scoliosis, kyphosis, and/or lordosis), tumor, pseudoarthrosis, and failed previous fusion.
Device Description
The Nexus Anterior Cervical Plate System consists of a variety of shapes and sizes of main plates, screws, sub-plates, rivets and associated instruments. The sub-plate is pre-assembled to the main plate and designed to prevent screws from backing out using the elastic behavior during the screw insertion. The rivets are pre-assembled to the main plate, which firmly attach the sub-plate component to the main plate. Each component is color anodized to differentiate the screw type and diameter and to facilitate the surgical process. The plates range in length to accommodate one, two, three, and four level procedures. Main plates are available from 20mm to 110mm. Screws are available in lengths from 10mm to 20mm in 2mm increments. The screws have either a 3.5mm or 4.0mm diameter. They are provided in fixed self-tapping, variable self-tapping, fixed self-drilling and variable self-drilling configurations.
More Information

No
The device description focuses on mechanical components and their physical properties, with no mention of software, algorithms, or data processing that would indicate AI/ML.

No.
A therapeutic device is typically involved in the treatment or rehabilitation of an ailment, directly addressing a health issue. This device, the Nexus Anterior Cervical Plate System, is an implant used for fixation in surgical procedures, not a device used for therapy or rehabilitation.

No

The device is an anterior cervical plate system intended for surgical fixation to the cervical spine, not for diagnosing medical conditions.

No

The device description clearly outlines physical components like plates, screws, sub-plates, rivets, and associated instruments, indicating it is a hardware device.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood, tissue, and urine, derived from the human body, solely or principally for the purpose of providing information concerning a physiological state, state of health, or disease or congenital abnormality.
  • Nexus Anterior Cervical Plate System: The description clearly states that this device is an implantable system intended for anterior fixation to the cervical spine. It is a physical device used in surgery to stabilize the spine.
  • Lack of Specimen Examination: The device description and intended use do not involve the examination of any biological specimens.

Therefore, based on the provided information, the Nexus Anterior Cervical Plate System is a surgical implant, not an In Vitro Diagnostic device.

§ 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.

Dear Mr. Palmer:

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
