A heel fracture sclerotic bone nonunion usually requires a new surgical procedure. In heel fracture with sclerotic nonunion, the bone marrow cavity of the broken end of the fracture is closed and the broken end is sclerotic. Without sufficient blood supply to the broken end, no new bone scab will be formed, and the fracture will not heal for a long period of time. When a sclerotic bone fracture occurs, it is usually less likely to heal with conservative treatment, and in most cases, surgery is required. The surgery involves opening up the sclerotic medullary cavity and drilling into the sclerotic area to increase blood supply. The fracture needs to be re-fixed with strong internal fixation and extensive bone grafting. Once a heel fracture with sclerotic nonunion occurs, it is recommended that the patient go to the hospital as soon as possible to have the cause of the fracture clarified and receive proper treatment.
