Is surgery required for poor fibrous structure of bone? This is a question that most patients are concerned about. The answers are as follows: (1) If the pathology of fibrous dysplasia is clear, relatively mature and without clinical manifestations, this fibrous dysplasia can be observed and does not require surgery. (2) If the fibrous dysplasia of the bone, the invasion is very wide, in adolescents, pain under weight, and MRI performance inflammation or reaction area is large, the fibrous dysplasia is relatively immature, the development is faster, we should pay attention to several questions, that is, is this diagnosis of fibrous dysplasia? Does surgery need to be performed immediately or can it be closely observed? The clinical answers to these questions actually need to be answered by a very specialized bone oncologist because of the many detailed information issues involved. (3) Is surgery necessary for adults or elderly people with occasional lesions resembling fibrous dysplasia? A diagnostic question must be clarified here, because many imaging (e.g. CT, MRI, X-ray) diagnoses are not a final and definitive diagnosis, but only a high probability clinical diagnostic reference. Therefore, such patients need to pay attention to put some effort on the diagnosis, and if pathologically poor fibrous structure is confirmed and there is no clinical manifestation, surgery can be avoided, although local biopsy is often required clinically.
