Intramedullary bone graft

Intramedullary bone transplantation is to take a long bone from one end of the autologous tibia or diseased bone, and after repair, it can be inserted into the medullary cavity of both fracture ends to stabilize the fracture ends and stimulate bone formation. However, due to the limited length of its insertion into the medullary cavity and the small diameter of the bone graft, the internal fixation has little effect and is easy to break, so it is rarely used alone. Generally used only as an adjunct to other bone grafts, to accelerate the osteogenesis of the endosteal bone, or to treat the nonunion of short bones of the hands and feet.
