Author information

Avascular osteonecrosis (AON) has increased in the last few years in patients infected with the human immunodeficiency virus type-1 (HIV-1). The most commonly affected bone is the femoral head and neck. Frequently these bilateral and clinical findings include moderate to severe pain and functional impotence of the affected joints. The etiology is multifactorial and highly active antiretroviral therapy (HAART) with protease inhibitors (PI) is probably related to its development. In the evolution, a total hip replacement may be needed. We present an hemophilic patient with AIDS, who developed a bilateral AON of the femoral head and neck during HAART.
