Abstract
Although the understanding of the mechanical properties and fracture behaviour of  bone is continuously improving, as yet it's far from complete. So, this paper represents  an experimental study about the effect of static and dynamic loads under different  parameters on intact bone and human hip joints. The same test will be applied on the  human hip joints after insertion of the artificial femur component in the bone. 
A special test-rig was designed in order to fix both natural and artificial implant and  expose them to a state of loading similar in magnitude and direction to that encountered in the human-being.
A comparison between the stress-strain distribution of the intact  and artificially implanted bones were conducted by using strain gauges. 
The results showed that the stresses were reversed after insertion of the artificial  femoral component and the stresses were maximum at the near of the tip of the  prothesis. Also, the absence of the collar-calcar causes a severe reduction of the  stresses which may be due to important metabolic changes.
