Autologous bone is the best bone graft. Autogenous bone has two advantages. First, it heals quickly. Second, there will be no exclusion. However, its shortcomings are also obvious, that is, the amount of bone taken is small, and the places where bone can be taken are limited. Ilium and small bone cysts are ok, but large bone cysts are still not.
However, if there are not enough bones in the bone cyst, the popular method now is to use allogeneic bones, that is, bones that have been treated by others.
Now there is a new method, which is to make a hole in the femur, take bone marrow from the femur, and then implant it as a bone coat, but this operation is basically not done. One is the need for special tools, and the other is that the patient is too painful.
Is there any influence after bone cyst bone grafting? If it is autologous bone, there will be no rejection, and the fusion degree is high, but the bone mass is limited, especially in children. Because of the incomplete development of children, the available bone mass is not much, which is easy to cause different degrees of damage to the bone donor area and increase the pain of patients.
Allogeneic bone comes from many sources, and its biological characteristics and morphological structure are similar to those of autologous bone, but there is a certain rejection.
Therefore, at present, bone cysts and bone grafts are usually a mixture of autologous bone and allogenic bone. Although rejection can not be ruled out, it is still rare in clinic, and artificial bone is not considered.
Is bone cyst scraping a major operation? Bone cysts usually require surgical treatment. Surgery is generally to open a bone window at the site of the cyst, scrape out the focus of the bone cyst, burn the cyst wall, then rinse it, and finally implant it into the bone. After bone implantation, the incision can be closed. Surgery is generally this process, so bone cyst scraping and bone grafting is not a major operation.
4. How long was the hospital stay for bone cyst surgery? The average hospitalization time of bone cyst surgery is 7- 10 days, because it takes 2-3 days to check after hospitalization. After the operation is completed, it is generally necessary to observe in the hospital for 4- 10 days. This is mainly based on the healing of the incision. If the incision is not infected, there is no local skin exudation and there is no skin damage, you can consider leaving the hospital.
