title: [Osteonecrosis of the femoral head in HIV-positive patients].
abstract: Since the introduction of more effective antiretroviral therapy in HIV treatment, an increase in survival and in the quality of patients' life has been observed, due to the dramatic reduction in commonly occurring opportunistic diseases. The appearance of new clinical cases has, however, been observed, previously unrecorded probably due to the quicker negative evolution of AIDS. Pathologies such as lypodistrophy, cardiomyopathy, immune disease, are extremely widespread and partly linked to the natural history of HIV infections, and partly to the side effects of the treatments. Among such diseases, femoral head necrosis seems to occur fairly frequently and is characterised by a quick evolution. The emergence of coxalgia in HIV patients requires an early diagnosis through NMR or bone scan. Given the usual evolution of this pathology and the problems related to antiviral treatment, conservative treatment seems to have little possibility of success. A surgical replacement becomes essential in cases of invalidating necrosis, but there are still unresolved questions as regards risks of infection, bone integration, as well as local and systemic reactions to the prosthetic debris.
