DONATE TISSUE!
Health and mobility. Many bone diseases can nowadays be cured with bone allografts. With your donor you can make a difference. 

To replace lost bone (e. g. due to trauma, inflammatory processes or tumour removal) and support bone regeneration, bone matrix of various origin can be used. Of all available options, autologous material is considered the gold standard, as vital cells and osteoinductive mediator proteins have a positive impact on the biological activity of the material. Moreover, there is no risk of immunogenicity or disease transmission, creating ideal conditions for efficient bone healing.

However, availability of sufficient amounts of autologous bone from various donor regions is limited. Larger amounts of cortical and cancellous bone can be collected from the iliac crest. However, this can result in nerve damage or pelvic instability and the collected tissue has high resorption rates. Moreover, there is an additional surgical site for the collection of autologous bone, that can in turn be associated with further bone defects, pain, and potential morbidity at the collection site.1-3 Therefore, the use of processed allogeneic bone tissue is a viable alternative to autologous transplants.

Both processed allogeneic bone and autologous tissue have the same immunologic compatibility and the blood plasma of these patients has no circulating antibodies detectable.4 Moreover, there is radiographic, histologic and morphologic evidence that autograft and allograft are identical in the final stage of incorporation.5-8

Allogeneic

  • Bone of human donors
  • Natural bone structure and composition

Xenogeneic

  • From another species, mostly of bovine origin (cattle)
  • Long-term volume stability

Synthetic / Alloplastic
