Radiological abnormalities of the skeleton in patients with sickle-cell anemia. A study of 222 cases in Tunisia.

The way in which bones are affected in cases of sickle-cell anemia is well known. Nevertheless, advances in treatment and in methods of transfusion mean that we are increasingly seeing cases of older patients with this disease. A retrospective analysis of 222 cases of sickle-cell anemia demonstrates the radiological appearance of the skeleton in the disease and reveals the various bone segments which are particularly vulnerable at certain periods of life. Correlation of X-rays permits the discovery of lesions which are not clinically apparent. The frequency and characteristics of epiphyseal osteonecrosis and osteitis are studied. Aggravation of the bone lesions when corticoids are administered poses the problem of differential diagnosis of the disease, especially in comparison with rheumatic fever.
