Arthrose destructrice rapide ou rapidement progressive

Rapidly destructive osteoarthritis (RDOA) is considered as a rare and poorly diagnosed disease. RDOA is a destructive arthropathy that occurs most commonly in elderly women. The most typical radiological features are narrowing of the articular cartilage (chondrolysis) subchondral bone fracture, cysts in the femoral head/acetabulum, absence of osteophytes, flat femoral heads, and signs of joint effusion. RDOA was originally described in the hip but may also involve the shoulder and the knee. Pathogenesis is not well understood, but subchondral fracture probably plays a role in the development of destruction of the joint. Nevertheless, early diagnosis of the patients with rapid destructive arthritis of the hip is important to try to reduce complexity of surgical intervention.
