What is an allogeneic bone graft?
An allogenic bone graft is done using human bone, but unlike other types of bone grafts, the bone is not harvested from the patient receiving the graft. Instead, it is donor bone, typically harvested during other surgeries, such as hip surgeries. The bone is cleaned, sanitized, and meticulously prepared for donation.
What is a calcaneal bone graft?
The calcaneus is a superior source of bone graft in terms of minimizing surgical time due to its close proximity to the primary surgical site. Calcaneal bone graft is a particularly useful compliment to arthrodesis procedures and fracture repair within the forefoot and the midfoot.
What is a cancellous bone graft?
Cancellous bone grafts consist predominantly of trabecular bone tissue. Cancellous bone has higher osteogenic and osteoinductive properties than cortical bone and a larger number of progenitor cells and osteoblasts. The structure of cancellous bone allows rapid revascularization of the graft.
What is a non autogenous graft?
Non-autogenous grafts are available either as allogeneic or xenografts. Allogenic bone grafts are obtained from genetically dissimilar donors of the same species, whereas xenografts are obtained from a different species . These grafts are available as mineralized, demineralized, fresh, frozen, or freeze-dried bone.
What is the meaning of bone grafting?
Bone grafting is a surgical procedure that uses transplanted bone to repair and rebuild diseased or damaged bones. A bone graft is a choice for repairing bones almost anywhere in your body. Your surgeon might take bone from your hips, legs, or ribs to perform the graft.
What is the heel called?
The calcaneus (heel bone) is the largest of the tarsal bones in the foot. It lies at the back of the foot (hindfoot) below the three bones that make up the ankle joint.
What is cancellous bone example?
Cancellous bone, also known as spongy or trabecular bone, is one of the two types of bone tissue found in the human body. Cancellous bone is found at the ends of long bones, as well as in the pelvic bones, ribs, skull, and the vertebrae in the spinal column.
What is the difference between cancellous and cortical bone?
A Cortical and Cancellous Bone Cortical bone is a dense tissue that contains less than 10% soft tissue. Cancellous or spongy bone is made up of trabecules shaped as plates or rods interspersed between bone marrow that represents more than 75% of the cancellous bone volume.
What is an autogenous vein?
Abstract. Autogenous vein tissue is recognized as the preferred material for extremity revascularizations that require the use of a conduit. However, the results after vascular repair of injured extremity arteries with autogenous vein interposition or bypass grafts have not been well defined.
What is bone graft used for?
What is bone graft made of?
Alloplastic grafts may be made from hydroxyapatite, a naturally occurring mineral (main mineral component of bone), made from bioactive glass. Hydroxyapatite is a synthetic bone graft, which is the most used now due to its osteoconduction, hardness, and acceptability by bone.
What is the function of heel?
Its phalanges and metatarsal bones are large and strong. Together, the tarsal and metatarsal bones of the foot form a longitudinal arch, which absorbs shock in walking; a transverse arch, across the metatarsals, also helps distribute weight. The heel bone helps support the longitudinal foot arch.
