Dead bone removal

Small dead bones can often liquefy into pus, or they can be discharged into the body or soft tissue with the pus. However, the larger dead bone cannot be discharged, and it remains in the bone cavity as a foreign body, which is the root cause of the persistent and unhealed infection and must be removed by surgery. Preoperative x-ray films confirmed the existence of dead bones, which had been completely separated from the surrounding tissues, and sufficient new bone cladding was formed around them. It is estimated that surgery can only be performed when pathological fractures do not occur under protection.
