Intended Use

The Trinica Select Anterior Cervical Plate System is intended for anterior interbody screw fixation of the cervical spine at levels C2-T1. The System is indicated for use in the temporary stabilization of the anterior spine during the development of cervical spinal fusions in patients with degenerative disc disease (as defined by neck pain of discogenic origin of the disc confirmed by patient history and radiographic studies), trauma (including fractures), tumors, deformity (defined as kyphosis, lordosis, or scoliosis), pseudoarthrosis, and/or failed previous fusions. WARNING: This device is not approved for screw attachment to the posterior elements (pedicles) of the cervical, thoracic, or lumbar spine.

Device Story

Trinica Select Anterior Cervical Plate System provides temporary anterior spinal stabilization during fusion. System components include titanium alloy cervical plates, preassembled locking caps, and fixed/variable angle bone screws. Locking caps feature tabs to prevent screw back-out. Plates available in one-level to four-level configurations; screws available in various lengths and diameters. Device used by surgeons in clinical/OR settings to fixate cervical spine segments. Surgeon implants hardware to maintain alignment and stability while bone fusion occurs. Benefits include mechanical support for spinal segments during healing process.

Clinical Evidence

Bench testing only. No clinical data provided. Testing evaluated design modifications against established criteria to ensure safety and effectiveness.

Technological Characteristics

Materials: Titanium alloy (ASTM F136). Surface treatment: Titanium anodization (AMS 2488 Type II). Components: Cervical plates, locking caps, fixed/variable angle bone screws. Form factor: 22mm-92mm plate lengths; 10mm-18mm screw lengths. Mechanical fixation principle.

Indications for Use

Indicated for patients requiring temporary anterior cervical spine stabilization (C2-T1) during fusion. Conditions include degenerative disc disease, trauma (fractures), tumors, deformity (kyphosis, lordosis, scoliosis), pseudoarthrosis, and failed previous fusions. Contraindicated for posterior element (pedicle) attachment.

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.

{1}------------------------------------------------

#### Device Description:

The Trinica Select Anterior Cervical Plate System is a fixation device consisting of cervical plates, locking caps, fixed bone screws and variable angle bone screws made from titanium alloy in conformance with ASTM F136. The locking cap is preassembled onto the plate and is designed with tabs that prevent bone screws from backing out. The plates and locking caps are treated with titanium anodization per AMS (Aerospace Material Specification) 2488 Type II. Bone screws are subjected to a color anodizing process to differentiate the screw type and diameter

Plates are offered in one-level, two-level, and four-level fusion configurations (22 mm through 92 mm). Bone screws are available in lengths from 10mm through 18mm in 1mm increments. The screws have either a 4.2 inch 4.6 inch diameter. Fixed angle and variable angle screws are available.

#### Intended Use:

The Trinica Select Anterior Cervical Plate System is intended for anterior interbody screw fixation of the cervical spine at levels C2-T1. The System is indicated for use in the temporary stabilization of the anterior spine during the development of cervical spinal fusions in patients with degenerative disc disease (as defined by neck pain of discogenic origin of the disc confirmed by patient history and radiographic studies), trauma (including fractures), tumors, deformity (defined as kyphosis, lordosis, or scoliosis), pseudoarthrosis, and/or failed previous fusions.

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

#### Comparison of Required Technological Characteristics

The Trinica Select™ Anterior Cervical Plate System is substantially equivalent to the predicate Synthes anterior cervical spine system (K945700, concurrence date July 20, 1995). The table below provides a comparison of equivalency characteristics.

| Characteristics | Equivalency |
|-----------------------------------|--------------------------|
| Intended Use | Identical |
| Anatomical Sites | Identical |
| Target Population | Identical |
