UMD: Grafts obtained from a donor or produced artificially (i.e., synthetic) for the structural replacement of a diseased or injured bone. These grafts may be of biological origin, obtained from the body of the same person (i.e., autograft), from another person (i.e., allograft, typically from cadavers), from other natural sources (e.g., natural hydroxyapatite), or less frequently, from a different animal species (i.e., xenografts). These grafts may be made of synthetic materials such as ceramic and synthetic polymer or a combination of natural and synthetic materials (i.e., composite grafts), including living elements and synthetic materials developed using bioengineering techniques (i.e., bioartificial). Bone grafts are used for reconstructive and/or plastic surgery to increase body mass and provide mechanical support; they may also provide a framework for bone growth.,MEDLINEPLUS: <p>A bone graft transplants bone tissue.
