The human skeleton loses bone mass with increasing age. A wide variety of evidence suggests that the skeleton compensates for this decreased bone mass by increasing the second moment of area in the midshaft of long bones. Strain is the mechanical transducer of bone's adaptation to its mechanical environment. In the absence of strain, bone resorption occurs. Contemporary femoral prostheses are stiffer than the cortical bone that serves as their host and, therefore, induce stress shielding and… CONTINUE READING
