• Device Name: MODIFICATION TO VERTEX RECONSTRUCTION SYSTEM
• Applicant: Medtronic Sofamor Danek, Inc.
• Product Code: KWP · Orthopedic
• Decision Date: Oct 1, 2004
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 888.3050
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

When intended to promote fusion of the cervical spine and the thoracic spine, (C1-T3), the VERTEXTM Reconstruction System is indicated 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. 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 screws (3.5mm and 4.0mm cancellous, and 4.0mm cortical) is limited to placement in T1-T3 in treating thoracic conditions only. Screws are not intended to be placed in the cervical spine. Titanium ATLAS™ Cable used with the VERTEX™ Reconstruction System allows for cable attachment to the posterior cervical or thoracic spine.

Device Story

Posterior spinal fixation system; consists of rods, hooks, screws, multi-axial screws, and connecting components; fabricated from medical grade titanium or titanium alloy; includes Nitinol (NiTi) retaining ring for multi-axial screws. Surgeon-operated in clinical/OR setting; components rigidly locked to rods to create patient-specific constructs; provides stabilization to promote fusion. Modification includes updated tulip head design to smooth post screw, plus updated offset connector and eyebolt connection. Titanium ATLAS™ cable system optional for attachment. Not for use with stainless steel.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Materials: Medical grade titanium, titanium alloy, and Nitinol (NiTi) shape memory alloy. Components: Rods, hooks, screws (3.5mm, 4.0mm, 4.5mm), multi-axial screws, offset connectors, eyebolts. Connectivity: None. Energy source: None. Sterilization: Not specified.

Indications for Use

Indicated for patients requiring cervical and thoracic (C1-T3) spine fusion due to DDD, spondylolisthesis, spinal stenosis, fracture, dislocation, failed previous fusion, or tumors. Screws are restricted to T1-T3 thoracic use only; not for cervical spine.

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.

#### III. Description:

The VERTEX™ Reconstruction System is a posterior system, which consists of a variety of shapes and sizes of 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 tailormade for the individual case. Titanium ATLAS™ cable may be used with this system at the surgeon's discretion.

The VERTEX™ Reconstruction System is fabricated from medical grade titanium or titanium alloy. The VERTEX™ Reconstruction System also includes a retaining ring for the multi-axial screw made of Shape Memory Alloy (Nitinol - NiTi). Shape Memory Alloy is compatible with titanium or titanium alloy implants only. Do not use with stainless steel.

The purpose of this submission was to modify the existing tulip head design into a smooth post screw, and to update the offset connector and eyebolt connection.

#### IV Indications

When intended to promote fusion of the cervical spine and the thoracic spine, (CI-T3), the VERTEX™ Reconstruction System is indicated 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.

#### 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.

### Screws/Connectors

The use of screws (3.5mm, 4.0mm and 4.5mm cancellous and 4.0mm cortical) is limited to placement in T1-T3 in treating thoracic conditions only. 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.

#### V. Substantial Equivalence:

Documentation has been provided which demonstrates that the VERTEX™ Reconstruction System is substantially equivalent to VERTEX™ Reconstruction System that was previously cleared in K023555 and K003780.
