Abstract

Osteoporosis is a condition where the amount of bone deposited becomes less than the amount of bone resorbed. The bone becomes porous, less dense and begins losing its mechanical integrity. Measurements of bone shape as the area moment of inertia of the cross-section, and bone density and area as the mass moment of inertia of the cross section are discussed. The spine experiment showed that from L3 to L5 there is a consistent increase in the vertebral area. There is only a moderate increase in bone density. The area ellipticity increases significantly from L3 to L5. The mass ellipticity, however, is constant from L3 to L5. The procedure is fast and accurate and it can be performed in vivo.
