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.
The needle is inserted through the bone's hard cortex and into the soft marrow interior, which allows immediate access to the vascular system. The IO needle is positioned at a 90-degree angle to the injection site, and is advanced through manual traction, impact driven force, or power driven.
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.
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).
When a bone fractures, the fragments lose their alignment in the form of displacement or angulation. For the fractured bone to heal without any deformity the bony fragments must be re-aligned to their normal anatomical position. Orthopedic surgery attempts to recreate the normal anatomy of the fractured bone by reduction of the displacement.
These growth factors modulate the differentiation of progenitor cells into osteoprogenitor cells, which are responsible for bone and cartilage formation. As a result of the demineralization process, DBM is more biologically active than undemineralized bone grafts; conversely the mechanical properties are significantly diminished. [citation needed]
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.
