Abstract
The ankle joint acts like a hinge. But it’s much more than a simple hinge joint. The ankle is actually made up of several important bones and their associated assembly. The exceptional assemblage of the ankle makes it a very stable joint. This joint has to be stable in order to withstand 1.5 times our body weight when we walk slowly and up to eight times our body weight when we run at a high speed or jump.

Problems
-
1.
What are the ranges of movement of the ankle joint? What are the force variations during normal walking? How can an engineer approach finding them? Search the Internet for a possible solution.
-
2.
Sketch the components of the ankle joint in an isometric view and then develop the top view and front view in half-section and side views.
-
3.
How will you approach the development of an artificial ankle joint of the left foot, including the ankle joint, which was irreversibly damaged in a road Âaccident? Sketch each part and indicate the material to be used. How will you get the dimensions of the joints? What methods are to be applied to manufacture the components? Consult Fig. 13.3 for help.
