Allogenic bone is derived from living or cadaver donors and, like blood and blood products, it carries infection risks.
Allogenic bone marrow transplant: The term allo means other. Stem cells are removed from another person, called a donor. Most times, the donor's genes must at least partly match your genes. Special blood tests are done to see if a donor is a good match for you. A brother or sister is most likely to be a good match. Sometimes parents, children, and other relatives are good matches. Donors who are not related to you may be found through national bone marrow registries.
The application of the H-shaped allogeneic bone graft combined with spinous process replantation can well reconstruct the posterior spinal canal, and also can effectively avoid iatrogenic spinal stenosis, so it is worthy of promoting in the clinical treatment of intraspinal tumor surgery 1).
