`
`The VERTE-STACK™ TELAMON™ PEEK Vertebral Body Spacer 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™ TELAMON™ device is to be used with supplemental
`fixation. Specifically, the VERTE-STACK™ TELAMON™ device is to be used with the Medtronic Sofamor Danek ZPLATE II Anterior Fixation System, Titanium
`DYNALOK™ CLASSIC Spinal System, the VANTAGE™ Anterior Fixation System, Titanium TSRH® Spinal System, Titanium CD HORIZON® Spinal System, the
`Titanium GDLH® Spinal System, or their successors. Additionally, the VERTE-STACK™ TELAMON™ device is intended to be used with bone graft.

`
`PEEK Material Advantages
`
`Radiolucency
` • Easier visualization of bone growth
` • Minimal scatter or artifact with CTs and MRIs
`
`Biocompatibility
` • Long history of usage
` – Dental Implants
` – Heart Valves/Stents
` – Artificial Joints
` – Finger Implants
` – Spinal Implants
`
` Strength
` • Offers greater impact resistance
` • High ultimate strength
` • High fatigue strength
`
`Wear Resistance
` • Minimal wear debris was generated
`during fatigue testing
`
`Modulus of Elasticity
` • Elastic (Young’s) Modulus between
`cancellous and cortical bone
` • Ideal load sharing implant
`
`Modulus of Elasticity (MOE)
`Modulus of Elasticity is a measure of a material’s stiffness.
`The higher the Modulus of Elasticity, the stiffer the material.
`The lower the Modulus of Elasticity the better the load
`sharing.
`PEEK
`• 50% less stiff than CFRP
`• More closely approximates the MOE of cancellous bone,
` making it a better load sharing device.
