Cancellous bone graft

Cancellous bone transplantation has the advantages of large osteogenic stimulation, fast crawling replacement process, strong anti-infective power, and can form fragments to fill any cracks between bone ends. Therefore, it has a wide range of applications. Its disadvantages are soft texture and weak internal fixation. Therefore, it is often used clinically with cortical bone transplantation or metal internal fixation. Generally, cancellous bone transplantation is mostly used for filling of bone cavity, joint fusion, fracture nonunion, bone defect, etc. formed after bone tumor or inflammation scraping. In addition, cancellous bone fragments can also be used to reduce fractures of poor blood supply (such as when the tibial fracture of the lower third) can be transplanted to promote fracture healing. The sacrum has more high-quality cancellous bone. When a large amount of cancellous bone is needed, it can be taken from the sacrum; it can also be taken from the ribs. When a small amount of cancellous bone is needed, it can be taken near the end of the diseased bone, but it contains more fat and is of poor quality.
