Aspects of osteo-articular complications in sickle-cell disease on planar bone scintigraphy (infection excluded). Apropos of three cases

Skeletal complications of sickle-cell anemia are multiple and can appear on the acute (osseous infarction, acute osteomyelitis) or chronic mode (osteonecrosis, chronic osteomyelitis). The radio-labelled diphosphonate bone scintigraphy remains an important tool in the early diagnosis and in the follow-up of these complications and must form part of the initial assessment of the disease. Through clinical observations, the authors undertake to sum up the bone scintigraphy aspects of these complications. (author)
