[Epidemiology of idiopathic osteonecrosis of the femoral head in Japan]
Abstract
The Ministry of Health, Labour and Welfare (MHLW) designates idiopathic osteonecrosis of the femoral head (ION) as so-called "intractable diseases" and has been promoting research. To summarize descriptive or analytic epidemiology of the ION in Japan, we present findings obtained through nationwide studies with the support of MHLW.
