No
The description focuses on the mechanical components and materials of a cervical plate system, with no mention of AI or ML capabilities.
Yes
The device is intended for anterior fixation to the cervical spine to treat various spinal conditions like degenerative disc disease, trauma, and deformities, which are therapeutic interventions.
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 states it consists of physical components like plates, screws, sub-plates, and rivets, fabricated from titanium alloy. This indicates it is a hardware medical device, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is for "anterior fixation to the cervical spine." This is a surgical implant used directly on a patient's body.
- Device Description: The description details physical components like plates, screws, and rivets made of titanium alloy, designed for surgical implantation.
- Lack of IVD Characteristics: An IVD device is used in vitro (outside the body) to examine specimens (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening. This device does not perform any such function.
The information provided describes a surgical implant, not a diagnostic test performed on biological samples.

Intended Use / Indications for Use
The REX 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
Rex Cervical Plate System consists of a variety of shapes and sizes of Main Plates, screw, sub-plate, rivets and the 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 also pre-assembled to the main plate and designed to assemble the sub-plate to the main plate firmly. Each component is subjected to a color anodizing process to differentiate the screw type and diameter and to make the surgical process easy. The plates range in length to accommodate one, two, three, and four level procedures. Main plate 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 fixed self-tapping, Variable self-tapping screw, fixed self-drilling screw, Variable self-drilling and are available in lengths ranging from 10mm to 20mm in 2mm increments
The Rex Cervical Plate System components are supplied non-sterile, are single use and are fabricated from titanium alloy (Ti-6AI-4V ELI) that conforms to ASTM F 136.

§ 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)
