Simulation of Osteoporosis Due to Agedness

Osteoporosis is a disease mainly of the elderly.A study of the effect of agedness on osteoporos is made.The simulation of osteoporosis due to agedness factor is been realized in computer with the model combined finite element method.Results show that when persons grow old,outside loads decline as a result of fall of muscle force and decrease of quantity of activity.When percentage of loss of bone mass to peak value bone mass is above 25,osteoporosis happens.Agedness factor can result in osteoporosis.This indicates the importance of mechanical factor in preventing and curing osteoporosis.
