Xenograft 

Xenograft bone is harvested from a different species, most commonly cows or pigs. It can differ from human bone is mineral content or structure, which may result in remodeling rates different from human bone. Due to concerns about a potential immune response, xenograft bone is treated at high temperatures to remove organic components.1

  • Osteoconductive
  • Can be less costly than natural bone
  • Slower remodeling may be desirable in some applications

*Autograft is partially demineralized, and therefore its osteoinductivity (signals) are unenhanced compared to grafts with fully demineralized bone.

  • As medical devices, each xenograft product will have specific indications listed in its Instructions for Use (IFU). 
  • All other use is considered off-label in contrast to allograft and autograft which can be used anywhere bone formation is needed.
  • LifeNet Health offers natural bone allografts with no xenograft component
