Intended Use

The Maxima™ 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 Story

Maxima™ Anterior Cervical Plate System is a spinal intervertebral body fixation orthosis used for anterior cervical spine stabilization. System components include main plates (various sizes/hole configurations), screws (variable and semi-fixed), sub-plates, and rivets. Sub-plates are pre-assembled to main plates to prevent screw back-out via elastic behavior. Components are color-anodized for identification. Device is non-sterile, single-use, and implanted by surgeons during spinal procedures. It provides mechanical fixation to support fusion and stabilize the cervical spine, potentially alleviating symptoms associated with DDD, trauma, or deformity.

Clinical Evidence

Bench testing only. Mechanical testing performed according to ASTM F1717-01 to validate structural integrity and performance compared to the predicate device.

Technological Characteristics

Materials: Titanium alloy (Ti-6AI-4V ELI) conforming to ASTM F 136. Components: Main plates, screws (3.5mm/4.0mm diameter), sub-plates, rivets. Features: Color-anodized components, variable and semi-fixed screw options. Mechanical testing: ASTM F1717-01. Supply: Non-sterile, single-use.

Indications for Use

Indicated for anterior cervical spine fixation in patients with degenerative disc disease, spondylolisthesis, trauma (fracture/dislocation), spinal stenosis, spinal deformities (scoliosis, kyphosis, lordosis), tumor, pseudoarthrosis, or failed previous fusion.

Regulatory Classification

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.

### Device Description

Maxima™ Anterior 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. Screws can be inserted in the center hole of Main Plate - S type. Main Plate - S type are offered in no hole, one hole, two hole, three hole and ranges from 24mm to 108mm. Screws are available in lengths from 10mm to 20mm in 1mm increments. The screws have either a 3,5mm or 4.0mm diameter. Variable screw and Semi-fixed screw are provided. Variable screw provides more rotational and translational degree of freedom than Semi-Fixed screws.

The Maxima™ Anterior 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.

### Indications for Use:

The Maxima™ 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.

### Statement of Technological Comparison:

Mechanical testing was carried out according to ASTM F1717-01 to validate the Maxima" Anterior Cervical Plate System. The testing demonstrated substantially equivalent to the ZEPHIR™ Anterior Cervical Plate System (K994239, K030327) in terms of intended use, materials, and anatomical sites.
