title: Bilateral protrusio acetabuli in sickle cell anemia.
abstract: Extreme bilateral protrusio acetabuli is an unusual complication of hematologic disease. We have described a patient with sickle cell anemia who had this complication probably as a result of osteopenia. Thus sickle cell anemia should be added to the list of potential causes of protrusio acetabuli.
