Intended Use

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

Device Story

Anterior cervical plating system for spinal fusion; provides temporary stabilization. System consists of plates (1-4 levels, 14-96mm) and screws. Features titanium clips holding plates in 'fully open' position during implantation; clips removed post-fixation to allow 2mm translational shortening per level. Used by surgeons in clinical settings. Provides mechanical stability to facilitate bone fusion; benefits patients by maintaining alignment during healing. Same screws and locking mechanism as predicate Reflex Hybrid ACP.

Clinical Evidence

Bench testing only. No clinical data provided. Substantial equivalence supported by engineering analysis and performance testing.

Technological Characteristics

Anterior cervical plate system; materials identical to predicate. Features titanium clips for translational adjustment (2mm per level). Uses same screws and locking mechanism as Reflex Hybrid ACP. Dimensions: 1-4 level configurations, 14-96mm lengths. Non-electronic, mechanical device.

Indications for Use

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

Intended Use

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

The Reflex® Translational 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)
- 피 Trauma (including fractures)
- Tumors
- E Deformities or curvatures (including kyphosis, lordosis, or scoliosis)
- 트 Pseudarthrosis
- 트 Failed previous fusion
- Decompression of the spinal cord following total or I partial cervical vertebrectomy
- 트 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 consists of various length plates that have Titanium clips which hold the plate in the "fully open" position. After the plate is placed and secured, Titanium clips are

removed allowing the plate to decrease in size up to 2mm per level treated. This translational plate design uses the same screws and locking mechanism used in the predicate Stryker Spine Reflex® Hybrid ACP System. Engineering analysis and performance testing verify that the subject device system is substantially equivalent in terms of performance characteristics to the predicate device systems.
