Graftech® Lumbar Allografts
Frequently Asked Questions
  1. What are Graftech® Lumbar Allografts?
    • Posterior and anterior lumbar interbody grafts
    • OsteoActive® - osteoinductive load-bearing surfaces for faster incorporation
    • Shaped to restore lordosis
    • Ridges to resist graft expulsion
    • Convenience of non-frozen, tray-packed tissue
  2. What are OsteoActive® surfaces?
    3.
    • New technology for structural allografts, based upon Grafton® DBM experience
    • Surface demineralization to expose indigenous growth factors
    • Creates osteoinductive AND osteoconductive load-bearing surfaces
    • Promotes early incorporation with endplates by recruiting osteoblasts and progenitor cells
  3. What are the Graftech® Posterior Ramp and the Graftech® Anterior Ramp made of and what are their benefits?
    • Processed and machined from cortical bone, a natural, biologic material
    • Supports loads of the lumbar spine - high compressive, insertion, and push-out strength
    • May be remodeled over time
    • Load sharing with a similar modulus (stiffness) as vertebral bodies
    • Superior post-operative imaging clarity - able to visualize graft-endplate interface; no artifact as seen with metal cages
  4. What are the lordotic angles of the Graftech® Lumbar Allografts and why is lordosis important?
    • Graftech ® Posterior Ramp: 5° of lordosis
    • Graftech ® Anterior Ramp: 8° of lordosis
    • Graftech ® Lumbar Spacer: Parallel
  5. Are there any features to prevent movement of the Graftech® Posterior Ramp or Graftech® Anterior Ramp post-operatively?
    • Anti-expulsion ridges on the load-bearing surfaces
    • Resists subsidence and expulsion, providing stability for healing
  6. What are the indications for the Graftech® Lumbar Allografts?
    • Degenerative disc disease
    • Grade 1 Spondylolisthesis
    • Scoliosis
    • Tumors
    • Vertebral Fractures
    • Objective is to restore and maintain disc height and foraminal openings, and to achieve arthrodesis
