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 ...
Bone graft procedures consist of more than just the surgery itself. The complete three-month total cost of a complex posterolateral lumbar spine fusion bone graft supplemented with graft extenders ranges from a mean of approximately US$33,860 to US$37,227. [33] This price includes all visits in and out of the hospital for three months.
Articular cartilage stem cell paste grafting was initially described by Kevin R. Stone M.D., a San Francisco-based orthopedic surgeon, in 1997 .The technique was devised in response to reports that many of the contemporary cartilage restoration procedures lead to the development of fibrocartilage, not true hyaline articular cartilage.
Spinal fusion, also called spondylodesis or spondylosyndesis, is a surgery performed by orthopaedic surgeons or neurosurgeons that joins two or more vertebrae. [1] This procedure can be performed at any level in the spine (cervical, thoracic, lumbar, or sacral) and prevents any movement between the fused vertebrae.
Bone morphogenetic proteins (BMPs) are a group of growth factors also known as cytokines and as metabologens. [1] Professor Marshall Urist and Professor Hari Reddi discovered their ability to induce the formation of bone and cartilage, BMPs are now considered to constitute a group of pivotal morphogenetic signals, orchestrating tissue architecture throughout the body.
In the United States, more than 6.5 million bone defects and more than 3 million facial injury cases have been reported each year. More than 2.2 million bone graft procedures are performed worldwide per year. The common causes for bone graft are tumor resection, congenital malformation, trauma, fractures, surgery, osteoporosis, and arthritis. [7]
The transplant is called an allograft, allogeneic transplant, or homograft. Most human tissue and organ transplants are allografts. 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 ...
The process of undergoing alloplasty involves the construction of an alloplastic graft through the use of computed tomography , rapid prototyping and "the use of computer-assisted virtual model surgery." [1] Each alloplastic graft is individually constructed and customised according to the patient's defect to address their personal health issue ...
