Intended Use

The Cervical Plate is intended for anterior interbody screw fixation of the cervical spine. The system is indicated for use in the temporary stabilization of the anterior spine during development of a solid fusion in patients with the following conditions: - 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. However, this device is not intended for screw attachment or fixation to the posterior elements (pedicles) of the cervical, thoracic, or lumbar spine

Device Story

System consists of titanium alloy plates and self-tapping cortical screws; used for anterior interbody fixation of cervical spine. Surgeon implants device to provide temporary stabilization during bone fusion. Fixation achieved by inserting screws through plate holes into vertebral bodies. Used in clinical/surgical settings by orthopedic or neurosurgeons. Benefits patient by maintaining spinal alignment and stability during healing process. Device is purely mechanical; no electronic or software components.

Clinical Evidence

Bench testing only; performed according to ASTM F1717 standards.

Technological Characteristics

Materials: Anodized titanium alloy (Ti-6Al-4V) per ASTM F136. Components: Plates and 4.0mm self-tapping cortical screws. Principle: Mechanical fixation via screw-plate construct. No software or electronic components.

Indications for Use

Indicated for patients requiring temporary anterior cervical spine stabilization during fusion for degenerative disc disease, spondylolisthesis, trauma (fracture/dislocation), spinal stenosis, deformities (scoliosis, kyphosis, lordosis), tumor, pseudoarthrosis, or failed previous fusion. Contraindicated for posterior element (pedicle) fixation.

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.

Submitter Scient'x Batiment Calypso Parc Ariane 3 78284 Guyancourt FRANCE Contact person J.D. Webb 1001 Oakwood Blvd Round Rock, TX 78681 512-388-0199 Trade Name Cervical Plate Common name Anterior cervical plate Classification name Class II per 21 CFR section 888.3060 Product Code KWQ Equivalent Device Scient'x Anterior Cervical Plate (K013439).

#### Device Description

The Cervical Plate system consists of multiple sized plates and screws. All components are fabricated from anodized titanium alloy (Ti-6Al-4V) that conforms to ASTM F136. Fixation is provided by inserting screws through holes in the plate into the vertebral bodies of the cervical spine.

The screws utilized in the Cervical Plate are of the self tapping cortical type and are available in 04.0mm and a variety of lengths.

#### Intended Use

The Cervical Plate is intended for anterior interbody screw fixation of the cervical spine. The system is indicated for use in the temporary stabilization of the anterior spine during development of a solid fusion in patients with the following conditions:

- · degenerative disc disease (DDD) (defined as neck pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies),
- · s pondylolisthesis,
- · trauma (i.e., fracture or dislocation),
- · s pinal stenosis.
- · d eformities or curvatures (i.e., scoliosis, kyphosis, and/or lordosis),
- tumor,
- · p seudoarthrosis, and
- · failed previous fusion.

However, this device is not intended for screw attachment or fixation to the posterior elements (pedicles) of the cervical, thoracic, or lumbar spine

## Summary of Technological Characteristics Compared to Predicate Device

The Cervical Plate is similar in indications, material, design, geometry, screw locking mechanism, length, strength, and screw diameter, length and thread form.

#### Summary Nonclinical Tests

Testing was performed according to ASTM F1717.
