Intended Use

The Stryker Spine Aviator Anterior Cervical Plating (ACP) System is intended for use as an aid in cervical spinal fusion and is intended for unilateral fixation. The Aviator Anterior Cervical Plating System is intended for anterior intervertebral screw fixation of the cervical spine at levels C2-T1. The system is indicated for temporary stabilization of the anterior spine during the development of cervical spine fusions in patients with the following indications: - Degenerative Disc Disease (as defined by neck pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies) - Trauma (including fractures) - Tumors - Deformities or curvatures (including kyphosis, lordosis, or scoliosis) - Pseudarthrosis - Failed previous fusion - Decompression of the spinal cord following total or partial cervical vertebrectomy - Spondylolisthesis - Spinal stenosis WARNING: This device is not approved or intended for screw attachment or fixation to the posterior elements (pedicles) of the cervical, thoracic, or lumbar spine.

Device Story

Aviator Anterior Cervical Plating (ACP) System provides temporary anterior spinal stabilization during cervical fusion; intended for unilateral fixation. System comprises metal plates (1-4 levels; 12-96mm) and 4.0mm/4.35mm diameter bone screws (variable/fixed angle; self-drilling/self-tapping). Features "spring bar" anti-backout mechanism and modified screw heads. Used by surgeons in clinical settings to aid fusion at C2-T1 levels. Device provides mechanical support to spine; surgeon visualizes placement via standard radiographic imaging. Benefits include stabilization of spinal segments to facilitate fusion in patients with degenerative, traumatic, or deformity-related conditions.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Anterior cervical plating system; metallic plates and bone screws. Features "spring bar" anti-backout mechanism and modified screw heads. Variable and fixed angle screw options (self-drilling/self-tapping). Mechanical fixation device; no software or energy source.

Indications for Use

Indicated for patients requiring temporary anterior spinal stabilization during cervical fusion (C2-T1) for degenerative disc disease, trauma, tumors, deformities (kyphosis, lordosis, scoliosis), pseudarthrosis, failed fusion, post-vertebrectomy decompression, spondylolisthesis, or spinal stenosis. 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.

The Stryker Spine Aviator Anterior Cervical Plating (ACP) System is intended for use as an aid in cervical spinal fusion and is intended for unilateral fixation.

The Aviator Anterior Cervical Plating System is intended for anterior intervertebral screw fixation of the cervical spine at levels C2-T1. The system is indicated for temporary stabilization of the anterior spine during the development of cervical spine fusions in patients with the following indications:

- 트 Degenerative Disc Disease (as defined by neck pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies)
- Trauma (including fractures) 트
- 트 Tumors
- 트 Deformities or curvatures (including kyphosis, lordosis, or scoliosis)
- . Pseudarthrosis
- Failed previous fusion
- Decompression of the spinal cord following total or partial D cervical vertebrectomy
- I Spondylolisthesis
- . Spinal stenosis

WARNING: This device is not approved or intended for screw attachment or fixation to the posterior elements (pedicles) of the cervical, thoracic, or lumbar spine.

The intended use and materials of the subject anterior cervical plates are identical to those of the predicate anterior cervical plates. The predicate Reflex® Hybrid Anterior Cervical Plate (ACP) System consists of various size plates that are implanted and remain static. The subject system introduces various length plates that contain a new "spring bar" anti-backout mechanism similar to the existing Reflex Hybrid "locking ring" anti-backout mechanism. In addition to the new anti-backout mechanism
