[Bilateral avascular necrosis of the femur head in an HIV-positive male].

: We present a case of bilateral avascular necrosis at the hips of a HIV-positive male, without other predisposing antecedents. The only relevant analytic data was the positivity of anticardiolipin antibodies (aCL AB). We discuss the possibility that both in this case as in those previously described, HIV may have played a main role in the development of osteonecrosis.
