Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex, pose a significant health risk to the patient, or fail to heal properly. Some small or acute fractures can be cured without bone grafting, but the risk is greater for large fractures like compound fractures.
Demineralized freeze dried bone allograft, referred to as DFDBA, is a bone graft material known for its de novo bone formation properties. [1] It is used extensively in bone grafting of alveolar bone in oral and periodontal surgery.
Allograft bone is a logical alternative to autograft. However, it must be rigorously processed and terminally sterilized prior to implantation to remove the risk of disease transmission or an immunological response. This processing removes the osteogenic and osteoinductive properties of the graft, leaving only an osteoconductive scaffold. These ...
Artificial bone refers to bone-like material created in a laboratory that can be used in bone grafts, to replace human bone that was lost due to severe fractures, disease, etc. [1] Bone fracture, which is a complete or partial break in the bone, is a very common condition that has more than three million US cases per year.

Xenotransplantation is a cross-species tissue transplantation from animal to human. [10] [11] The development of blood vessel anastomosis opened the door for xenotransplantation during the 20th century, which led to numerous attempts in organ transplantations with tissues from nonhuman primates (NHPs).
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.
Implant that has been used for fixation of a broken wrist. Closed reduction internal fixation (CRIF) is reduction without any open surgery, followed by internal fixation. It appears to be an acceptable alternative in unstable distressed lateral condylar fractures of the humerus in children, but if fracture displacement after closed reduction exceeds 2 mm, open reduction and internal fixation ...
A Phemister graft is a type of bone graft which uses bone tissue harvested from the patient to treat slow-healing, or delayed union bone fractures. [1] Thus, it is a form of autotransplantation. Typically, the tissue used in the graft is cancellous bone harvested from the patient's Iliac crest and laid in strips across the fracture site.
