[Bilateral femoral cephalic osteonecrosis in a human immunodeficiency virus-infected child taking HAART].

Musculoskeletal complications are uncommon in HIV-infected patients. In adults, one manifestation is osteonecrosis which can be associated with risk factors such as alcohol consumption, smoking or use of corticosteroids. Such risk factors are rare in children. Over the last decade musculoskeletal complications have been observed in patients with advanced-stage disease or whose immune system has been reconstituted with highly active antiretroviral therapy (HAART). This complication has been reported in adults but to date not in children. We present the case of a 5-year-old child with AIDS (C stage 3) who developed osteonecrosis related to the advanced stage of the illness and to HAART. No risk factors were found.
