Abstract
The human skeleton gives the body rigidity, allows for locomotion and protects the organs. The figure shows that intact cortical bone is very strong. A segment of the tibia is able to carry a small car, and a screw inserted into the cortex of the thigh bone (femur) will take the load of three persons. Intact healthy bone resists appreciable amounts of load without failure, for example, when a parachute jumper lands. When bone is mechanically overloaded, for example by work or a traffic or sports accident, it fractures. Prior to the accident the bone was able to carry load without giving way. After the accident the fractured bone bends, buckles, shortens or twists when even a small load is applied.
