Femoral Expansion in Aging Women: Implications for Osteoporosis and Fractures

In femoral radiographs of 2030 aging women, the diameter of the midshaft periosteum increased as cortical thickness declined. Since the cortical area enlarged, periosteal accretion exceeded endosteal resorption. Since the section modulus increased more than did cortical area, the ratio of flexural failure resistance to crush resistance increased, in apparent contrast to the changes observed in the femoral neck.

On the incidence of senile osteoporosis.

Excerpt Physicians generally agree that senile osteoporosis is encountered with increasing frequency, presumably due to the lengthening life span achieved during the last several decades. Back pain...
