In orthopaedic medicine, a bone graft can be sourced from a patient's own bone in order to fill space and produce an osteogenic response in a bone defect. However, due to the donor-site morbidity associated with autograft, other methods such as bone allograft and bone morphogenetic proteins and synthetic graft materials are often used as alternatives.
It is contrasted with autotransplantation (from one part of the body to another in the same person), syngenic transplantation of isografts (grafts transplanted between two genetically identical individuals) and xenotransplantation (from other species).
Autograft: graft taken from one part of the body of an individual and transplanted onto another site in the same individual, e.g., skin graft. Isograft: graft taken from one individual and placed on another individual of the same genetic constitution, e.g., grafts between identical twins.
Bone grafts are used in hopes that the defective bone will be healed or will regrow with little to no graft rejection. [19] Besides the main use of bone grafting – dental implants – this procedure is used to fuse joints to prevent movement, repair broken bones that have bone loss, and repair broken bone that has not yet healed.

However, there was a period of failure to accomplish successful recovery for all the allografts longer than 4 cm. Therefore, 'The Peripheral Nerve Injury committee' did not support nerve allograft until, in the early 1970s the first successful clinical trials on longer grafts were reported by using a new combination of radiation and freeze ...
Celebrity autographs online can go for prices from $20 to $200,000 depending on the signature — especially for legacy artists like Jimi Hendrix and Freddie Mercury. "Cameo started with the idea ...
Grafts are inserted through a tunnel that is drilled through the shin bone (tibia) and thigh bone (femur). The graft is then pulled through the tunnel and fixated with screws. The two bright objects in this X-ray are screws in the thigh bone (above) and shin bone (below). Graft options for ACL reconstruction include:
All the graft is worthwhile, and that makes you even more determined to outshine others and put in the performance of a lifetime. You’re going places, and the material rewards will match the ...
