Hyperlordotic implants are those defined by a lordotic angle ≥16˚. Implants are designed with a large hollow region in the center to house autograft bone, allograft bone comprised of cancellous and/or corticocancellous bone, demineralized allograft with bone marrow aspirate, or a combination thereof. New bone formation through the implant is intended to provide long-term structural support and fusion at the implanted disc space.
The design incorporates “windows” through the implant to permit visualization of the graft material, and over time, formation of new bone. Devices incorporate Titan Surface Technologies™, where superior and inferior surfaces include either Chemtex™ or nanoLOCK™ surface treatments (MMN™) designed to improve fixation to the adjacent bone. nanoLOCK™ surface technology (MMN™) provides a microscopic roughened surface with nano-scale features.
The implant system includes integrated fixation (screws) for stabilizing the implants when placed in the interbody space. An implant holding feature was incorporated into the trailing surface of the implant to mate with the implant holder, and to facilitate placement of the implant into the interbody space. Screws include internal hex drive features matched to instrumentation for implantation. Implantable components are manufactured from medical grade titanium alloy (Ti6Al4V- ELI).
The Endoskeleton™ TAS Interbody System or Endoskeleton™ TAS Hyperlordotic Interbody System should only be implanted by surgeons experienced in the use of such implants and the required specialized spinal surgery techniques.
Benefits:
ALIF cage option for cases that require additional fixation without the need for supplemental posterior instrumentation- Features three integrated grit-blasted screws for immediate mechanical stability; allow for up to 10° of medial/lateral or anterior/posterior angular variation
- Unique texture of both cage and screw surfaces helps secure device in place upon implantation and helps to prevent screw back-out
- Available in thirty-six sizes for increased surgeon choice and improved anatomical fit
About ALIF Cages
Anterior lumbar interbody fusion (ALIF) is a spine surgery that involves approaching the spine from the front of the body to remove disc or bone material from in between two adjacent lumbar vertebrae. The disc material is then replaced by cage containing bone graft or bone morphogenetic protein.The ALIF cage maintains normal disc height as the bone graft fuses with the bone of the vertebrae above and below to stabilize the spine.
