Osteoarthritis (OA) is a degenerative joint disease and occurs mostly in knee and hip. It is expected that in future over one-fifth of the population over the age of 60 in Europe and in the United States will have signs and symptoms associated with OA, and that 30% of OA patients will experience disability and immobilization, hence the motivation for this research aimed at achieving new insights into this disease. This paper presents the first results obtained by a combination of two approaches: morphological and structural 3D analyses, obtained from high-resolution micro-CT reconstructions of trabecular bone in early and late stage hip OA.
