Intended Use

The VERTE-STACK® Spinal System is a vertebral body replacement device intended for use in the thoracolumbar spine (T1-L5) to replace a collapsed, damaged, or unstable vertebral body due to tumor or trauma (i.e., fracture). The VERTE-STACK® Spinal System is to be used with supplemental fixation. Specifically, the VERTE-STACK® device is to be used with the Medtronic Sofamor Danek ZPLATE II Anterior Fixation System, the DYNALOK™ CLASSIC Spinal System, the VANTAGE™ Anterior Fixation System, the TSRH® Spinal System, the CD HORIZON® Spinal System, the GDLH® Spinal System and/or their successors. Additionally, the VERTE-STACK® device is intended to be used with bone graft.

Device Story

VERTE-STACK® Spinal System consists of stackable, hemi-cylindrical PEEK-OPTIMA LT1 or titanium alloy cages; designed for vertebral body replacement in thoracolumbar spine (T1-L5). Components include hollow center and add-on cages of varying lengths, diameters, and angulations; assembled constructs are tailor-made for individual patient pathology. Device used in surgical setting by physicians; requires supplemental anterior/posterior spinal instrumentation for stability. PEEK constructs compatible with stainless steel or titanium fixation; titanium constructs restricted to titanium fixation. Provides structural support for vertebral space created by corpectomy; intended for use with bone graft to facilitate fusion/stability.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Materials: PEEK-OPTIMA LT1, titanium alloy, Tantalum/titanium markers. Form factor: Stackable hemi-cylindrical cages. Energy source: None (mechanical implant). Connectivity: N/A. Sterilization: Not specified.

Indications for Use

Indicated for patients requiring vertebral body replacement in the thoracolumbar spine (T1-L5) due to collapse, damage, or instability from tumor or trauma (fracture). Must be used with supplemental fixation and bone graft.

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.

#### Product Description V.

The VERTE-STACK® device consists of hemi-cylindrical center cages of various lengths and diameters, as well as hemi-cylindrical add on cages of various lengths, diameters and angulation. The assembled VERTE-STACK® device consists of three components (one hollow center cage, and two hollow add-on cages). The VERTE-STACK® components can be rigidly locked into a variety of configurations, with each construct being tailor-made for the individual case.

The design of the VERTE-STACK® device includes a variety of stackable components of different sizes and heights. The stackable components are designed to suit the individual patient pathology.

The VERTE-STACK® device may be used individually, or two or more may be stacked together in order to accommodate the individual anatomical requirements of the vertebral space created by the corpectomy.

The VERTE-STACK® Spinal System implant components are made of medical grade PEEK-OPTIMA LT1 along with a marker made from either Tantalum or titanium. Alternatively, VERTE-STACK® Spinal System may be manufactured from titanium alloy.

The VERTE-STACK® Spinal System must be used with additional anterior and/or posterior spinal instrumentation to augment stability. VERTE-STACK® constructs manufactured from PEEK may be used with stainless steel or titanium supplemental

fixation devices. Titanium VERTE-STACK® constructs may not be used with stainless steel supplemental fixation devices:

The purpose of this submission was to modify the geometry of the implants and to include additional sizes into the existing VERTE-STACK® Spinal System.

#### V. Indications

The VERTE-STACK® Spinal System is a vertebral body replacement device intended for use in the thoracolumbar spine (T1-L5) to replace a collapsed, damaged, or unstable vertebral body due to tumor or trauma (i.e., fracture). The VERTE-STACK® Spinal System is to be used with supplemental fixation. Specifically, the VERTE-STACK® device is to be used with the Medtronic Sofamor Danek ZPLATE II Anterior Fixation System, the DYNALOK™ CLASSIC Spinal System, the VANTAGE™ Anterior Fixation System, the TSRH® Spinal System, the CD HORIZON® Spinal System, the GDLH® Spinal System and/or their successors. Additionally, the VERTE-STACK® device is intended to be used with bone graft.

#### VI. Substantial Equivalence

Documentation, including mechanical test results, was provided which demonstrated that the subject VERTE-STACK® Spinal System components are substantially equivalent to the previously cleared VERTE-STACK® Spinal System (K060719, SE 4/12/2006; and K052931, SE 11/13/2005).
