1 |
A rare osteonecrosis disease characterized by death of bone cellular components secondary to an interruption of the subchondral blood supply, typically manifesting with unilateral or bilateral, unifocal or multifocal lesions usually located on the epiphysis, metaphysis and/or diaphysis of the femoral heads, knees, shoulders, ankles and/or wrists, leading to gradual onset of pain and progressive joint degeneration resulting in loss of function. Association with corticosteroid usage, alcoholism, hyperbaric events, radiation or cytotoxic agent exposure, hemoglobinopathies, and/or underlying autoimmune or metabolic disease, amongst others, has been observed. |

A rare bone disease characterized by avascular necrosis of the navicular bone in children. Patients present with sudden unexplained foot pain, inability to bear weight, and limping. Radiographic features include flattening, fragmentation, and patchy sclerosis of the navicular bone. Soft tissue swelling may be associated. The condition is most commonly unilateral and self-limiting. Boys are more often affected than girls. |
