CORLOK® allografts are unique corticocancellous allografts comprised of an anterior cortical face and a unique dovetail design permitting a precise interlocking fit with adjacent vertebrae. CORLOK® allografts are processed from donor vertebral bodies creating homologous spinal allograft implants. Specially designed instruments facilitate the insertion of the CORLOK® allograft.

Allograft key features

• Vertebral Body Corticocancellous Construct
  1. Combination of dense cancellous bone with anterior cortical surface provides immediate perfusion for rapid healing and optimized mechanical strength
• Unique Dovetail Design
  1. Permits precise interlocking fit of implant with adjacent vertebrae
  2. Lock and load design allows anterior column support for motion segment stability and healing
• Precise Implant Sizing
  1. Allows appropriate distraction to re-establish lordotic sagittal alignment and foraminal patency
  2. Maximum graft-to-host bone surface area contact for excellent load distribution and healing
• Strict Tissue Standards
  1. Fresh-frozen implant ensures optimal mechanical strength and consistent sizing

Unique Instrumentation

• Integrated instrumentation system completes implant site preparation in two simple steps
