Frequently Asked Questions

  1. What are Graftech® Lumbar Allografts?

    2.
    • 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?

    4.
    • 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?

    5.
    • 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?

    6.
    • 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
