Intended Use

When intended as an adjunct to fusion of the occipitocervical spine, cervical spine, and the thoracic spine, (Occiput-T3), the VERTEX® Reconstruction System is indicated for skeletally mature patients using allograft and/or autograft for the following: DDD (neck pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), spondylolisthesis, spinal stenosis, fracture, dislocation, failed previous fusion and/or tumors. The occipitocervical plate rods, plates, rods, occipital screws, and hooks are intended to provide stabilization to promote fusion following reduction of fracture/dislocation or trauma in the occipitocervical junction and the cervical spine. When used to treat these occipitocervical and cervical conditions, these screws are limited to occipital fixation only. The screws are not intended to be placed in the cervical spine. Occipitocervical constructs require bilateral fixation to C2 and below. Note: Segmental fixation is recommended for these constructs. The hooks and rods are also intended to provide stabilization to promote fusion following reduction of fracture/dislocation or trauma in the cervical/upper thoracic (C1-T3) spine. The use of multi-axial screws is limited to placement in T1-T3. The screws are not intended to be placed in the cervical spine. Titanium ATLAS® Cable System to be used with the VERTEX® Reconstruction System allows for cable attachment to the posterior cervical or thoracic spine. In order to achieve additional levels of fixation, the VERTEX® Reconstruction System may be connected to the CD HORIZON® Spinal System rods with the VERTEX® rod connectors.

Device Story

Posterior spinal fixation system consisting of plates, rods, hooks, screws, and multi-axial screws; used to stabilize occipitocervical, cervical, and upper thoracic spine (Occiput-T3) to promote fusion. Surgeon-implanted in clinical/OR setting. Components rigidly locked to rods to create patient-specific constructs. Includes Nitinol retaining rings for multi-axial screws and silicone elastomeric stakes. May be used with ATLAS® cable system or connected to CD HORIZON® system. Provides mechanical stabilization to support bone graft healing; benefits patients by correcting spinal alignment and facilitating fusion in trauma or degenerative cases.

Clinical Evidence

Bench testing only; no clinical data provided.

Technological Characteristics

Materials: Medical grade titanium, titanium alloy, cobalt chromium, Nitinol (NiTi) for retaining rings, and silicone adhesive for elastomeric stakes. System is a posterior spinal fixation orthosis. Components include plates, rods, hooks, and screws. Not compatible with stainless steel. Sterilization not specified.

Indications for Use

Indicated for skeletally mature patients requiring fusion of the occipitocervical, cervical, and thoracic (Occiput-T3) spine. Conditions include DDD, spondylolisthesis, spinal stenosis, fracture, dislocation, failed previous fusion, and tumors. Contraindicated for use with stainless steel components.

Regulatory Classification

Identification

A spinal interlaminal fixation orthosis is a device intended to be implanted made of an alloy, such as stainless steel, that consists of various hooks and a posteriorly placed compression or distraction rod. The device is implanted, usually across three adjacent vertebrae, to straighten and immobilize the spine to allow bone grafts to unite and fuse the vertebrae together. The device is used primarily in the treatment of scoliosis (a lateral curvature of the spine), but it also may be used in the treatment of fracture or dislocation of the spine, grades 3 and 4 of spondylolisthesis (a dislocation of the spinal column), and lower back syndrome.

- Proposed Proprietary Trade Name: VERTEX® Reconstruction System II.
- III. Classification Name(s): Spinal Interlaminal Fixation Orthosis; Class: II; Product Code(s): K WP and Regulation No .: 888.3050
- IV. Description: The VERTEX® Reconstruction System is a posterior system, which consists of a variety of shapes and sizes of plates, rods, hooks, screws, multi-axial screws, and connecting components, which can be rigidly locked to the rod in a variety of configurations, with each construct being tailor-made for the individual case. Titanium ATLAS® cable may be used with this system at the surgeon's discretion. See the package inserts of both of those systems for labeling limitations. The purpose of this submission is to add an adjustable Occipitocervical plate to the system.

The VERTEX® Reconstruction System is fabricated from medical grade titanium, medical grade titanium alloy, and medical grade cobalt chromium. Medical grade titanium, medical grade titanium alloy, and/or medical grade cobalt chromium may be used together. Never use titanium alloy, and or/cobalt chromium with stainless steel in the same construct. The VERTEX® Reconstruction System includes a retaining ring for the multi-axial screw made of Shape Memory Alloy (Nitinol - NiTi). Shape Memory Alloy is compatible with titanium, titanium alloy, and cobalt chromium implants only. Some components contain elastomeric stakes made of silicone adhesive commonly used in implantable medical devices. Do not use with stainless steel.

To achieve best results, do not use any of the VERTEX® Reconstruction System implant components with components from any other system or manufacturer unless specifically labeled to do so in this or another MEDTRONIC document. As with all orthopedic and neurosurgical implants, none of the VERTEX® Reconstruction System components should ever be reused under any circumstances.

#### V. Indications for Use:

When intended as an adjunct to fusion of the occipitocervical spine, cervical spine, and the thoracic spine, (Occiput-T3), the VERTEX® Reconstruction System is indicated for skeletally mature patients using allograft and/or autograft for the following: DDD (neck pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), spondylolisthesis, spinal stenosis, fracture, dislocation, failed previous fusion and/or tumors.

### Occipitocervical Components: Plate Rod/Plates/Rods/Occipital Screws/Hooks

The occipitocervical plate rods, plates, rods, occipital screws, and hooks are intended to provide stabilization to promote fusion following reduction of fracture/dislocation or trauma in the occipitocervical junction and the cervical spine. When used to treat these occipitocervical and cervical conditions, these screws are limited to occipital fixation only. The screws are not intended to be placed in the cervical spine.

Occipitocervical constructs require bilateral fixation to C2 and below. Note: Segmental fixation is recommended for these constructs.

### Hooks and Rods

The hooks and rods are also intended to provide stabilization to promote fusion following reduction of fracture/dislocation or trauma in the cervical/upper thoracic (C1-T3) spine.

### Multi-axial Screws/Connectors

The use of multi-axial screws is limited to placement in T1-T3. The screws are not intended to be placed in the cervical spine.

Titanium ATLAS® Cable System to be used with the VERTEX® Reconstruction System allows for cable attachment to the posterior cervical or thoracic spine.

In order to achieve additional levels of fixation, the VERTEX® Reconstruction System may be connected to the CD HORIZON® Spinal System rods with the VERTEX® rod connectors. Refer to the CD HORIZON® Spinal System package insert for a list of the CD HORIZON® Spinal System indications of use.

- Substantial Equivalence: Documentation was provided demonstrating that the VI. VERTEX® Reconstruction System is substantially equivalent to other commercially available posterior fixation systems and other pre-enactment devices including the VERTEX® Reconstruction System in K080805 (S.E. 4/18/08), K082728 (S.E. 1/16/09), and K052734 (S.E. 10/21/05). The results of mechanical testing performed for the subject VERTEX® Reconstruction System components were equivalent to the testing performed for the predicate VERTEX® Reconstruction System components,
