SummaryRadiographic examination is the key to the diagnosis of many skeletal abnormalities. It is essential that each bone be examined in its entirety, including the cortex, medullary canal (cancellous bone or spongiosa), and articular ends. The position and alignment of joints are determined. In children, the epiphysis and epiphyseal line or physis must be observed. The adjacent soft tissues are examined.
Obliteration of normal soft-tissue lines and the presence of a joint effusion are of particular importance. When disease is present, it is important to determine whether the process is limited to a single bone or joint or whether multiple bones or joints are involved. The distribution of disease is also a consideration. The presence and type of bone destruction and bone production, the appearance of the edges or borders of the lesion, and the presence or absence of cortical expansion and periosteal reaction are also noted. The radiographic findings are then correlated with the clinical history and the age and sex of the patient to arrive at a logical diagnosis. The diagnosis may be firm in some instances; in other cases, a differential diagnosis is offered because the exact diagnosis cannot be determined.
