The REGENT Anterior Cervical Plate System is 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 history and radiographic studies) Trauma (including fractures). Tumors Deformities or curvatures (including kyphosis, lordosis or scoliosis) Pseudoarthrosis Failed previous fusion Spondylolisthesis Spinal Stenosis THIS DEVICE IS ONLY TO BE USED IN SKELETALLY MATURE PATIENTS. WARNING: THIS DEVICE IS NOT INTENDED FOR SCREW ATTACHMENT OR FIXATION TO THE POSTERIOR ELEMENTS (PEDICLES) OF THE CERVICAL, THORACIC, OR LUMBAR SPINE.

Device Story

REGENT Anterior Cervical Plate System provides temporary anterior spinal stabilization during fusion. System comprises titanium alloy (Ti-6Al-4V) plates and screws; includes both self-tapping and self-drilling screw options. Used by surgeons in clinical settings to fixate cervical spine levels C2-T1. Plates and screws are anodized. Device provides mechanical support to facilitate bone fusion; surgeon selects screw type based on preference. Benefits include stabilization of spinal segments in patients with degenerative, traumatic, or structural spinal conditions.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing per ASTM F1717.

Technological Characteristics

Materials: Titanium alloy (Ti-6Al-4V, ASTM F-136/ISO 5832-3) for implants; stainless steel for instruments. Design: Multi-level plates (1-4 levels) and fixed/variable screws. Surface: Type II anodized. Mechanical testing: ASTM F1717 static compression, bending, and torsion. No software or electronic components.

Indications for Use

Indicated for skeletally mature patients requiring temporary anterior cervical spine stabilization (C2-T1) during fusion for degenerative disc disease, trauma, tumors, deformities (kyphosis, lordosis, scoliosis), pseudoarthrosis, failed fusion, 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.

### Summary of Non-Clinical Test

The self drilling screws and the cleared REGENT Anterior Cervical Plates were tested in static compression bending and torsion. This was performed in accordance with ASTM F1717, "Standard Test Methods for Spinal Implants and Constructs of a Vertebrectomy Model ", and was considered substantially equivalent to the self tapping screws used in the previously cleared REGENT Anterior Cervical Plate System (K091134).

## Summary of Clinical Test

Not Applicable.

#### Basis for Substantial Equivalence

The basis for substantial equivalence is described in this substantially equivalent to the predicate devices based on similarities in design, intended use, and material. Performance testing, design comparisons, and functional analysis conducted on these devices demonstrate that they are equivalent to the predicate devices. The addition of the self drilling screw has the following similarities

Intended Use: The proposed system has the same intended use as the previously clear

Materials: The proposed self drilling screws are made from the same material as the self tapping screw (Ti-6Al-4V, ASTM F-136, ISO 5832-3)

Lengths of the screws: The proposed lengths of the self drilling screws are provided in the same lengths and overall diameters (4.0mm and 4.5mm).

Mechanical Testing: The mechanical test results of the proposed self drilling screw device are substantially equivalent to the self tapping screw in the cleared REGENT Anterior Cervical Plate System (K091134).

Screw to plate interface: The proximal geometry of the subject self drilling screw has an identical geometry to the self tapping screw head (K091134), and result in identical interfaces between the REGENT Anterior Cervical Plate.

Modification to the device

- The addition of an acute angle tip screw (self drilling) as an alternative to the self tapping screw . in the previously cleared REGENT ANTERIOR Cervical Plate System (K091134).
