Allogeneic bone, also called homogeneous allogeneic bone, is of the same germline origin as the person, that is, it is taken from another person, and most of it originates from people who donate their remains. After the allograft bone is removed, it is specially treated and sterilized for clinical use. In clinical practice, it is mainly used for patients with bone defects, such as comminuted fractures or non-healing bone, and it is difficult to take the bone by itself. Fractures of the lumbar spine are repositioned, and bone grafting is also used for allograft bone. Generally, allograft bone is safer from regular manufacturers and is not prone to rejection, and healing with its own bone is relatively easy. It is still necessary to go to the hospital for x-ray examination to check the healing situation. At present, allograft bone is still widely used in clinical practice.
