Bone fibrous dysplasia is the replacement of bone trabeculae by fibrous tissue and is common in adolescent children and can occur singly or in multiple cases. The first presentation is with a pathological fracture, often without clinical symptoms before the fracture. In a large number of clinical cases, it has been found that either recurrence or re-fracture occurs with simple scraping and grafting or cemented reconstruction. The only reliable treatment is that the diseased bone and the previously surgically implanted bone without blood flow must all be removed, followed by the use of anastomotic bone graft! Otherwise, the more surgeries are done, the more local blood vessels are destroyed, the less bone is taken from the area (available for bone grafting), the more local soft tissue contracture, the more deformed the limb is, and the more difficult the surgery will be! We have dealt with many children with this disease, allogeneic bone is useless, and bone grafts that do not anastomose blood vessels are useless, no matter what bone graft is used, it will soon be absorbed! Recently, there was a little boy who had three surgeries in a major hospital in China (fracture in 06, three surgeries in Shanghai in 5 years), the first three surgeries took bilateral iliac bone grafts and fibula grafts, and the bone was absorbed soon after each surgery. Now the affected limb is 8cm shorter than the normal side and has a “C” shaped bend. Because of the high demand of bone grafting with anastomosis, it contains a strong sense of responsibility of the surgeon! The need to suture the blood vessels under the operating microscope and the thinness of the blood vessels in children requires a strong sense of responsibility! We hope that our colleagues will be careful in choosing the surgical method for their patients!
