Osteonecrosis en lupus eritematoso sistémico / Osteonecrosis in systemic lupus erythematosus

RESUMO

Osteonecrosis (ON) is a clinical entity characterized by aseptic necrosis of bone marrow and trabecular bone as a result of significant disruption of blood supply to the bone. In patients with systemic lupus erythematosus (SLE), ON is a well recognized complication, which also results in significant morbidity. The clinical course is usually progressive to end stage degenerative changes of the joints causing significant secondary pain and limitation of movement, and reducing the quality of life in these patients. Corticosteriod therapy is the major predisposing factor for ON in SLE. This article reviews the causes, clinical and epidemiological features, diagnosis and treatment options for ON among patients with SLE.
