[Pathological bone structure (author's transl)].

The pathological and anatomical basis of various radiographic changes in a number of diseases of the skeleton is discussed. The conditions include abnormalities of bone formation and bone removal, including osteoporosis, fibrous dysplasia, osteomyelosclerosis, osteitis deformans, posttraumatic changes and ossifying periostitis. The form and structure of the pathological and anatomical substrate determine the radiological appearances and are essential for arriving at a diagnosis.
