Abstract

About 10 - 20% of the elderly is falling every year, and 10 percent of them is suffered from fracture. Whether or not the fractures occur from the fall is determined by the bone strength and the load on the bone. The proximal femurs of the elderly fracture due to the load of 2,100 - 4,000N, although the load on the greater trochanter from falls is 5,600 - 8,600N. Thus, the external force from falls is never negligible. Fracture risk varies greatly depending on the conditions such as the muscle tension and the load direction.
