[Anatomy and biomechanics of the upper ankle joint].

The ankle joint as a component within the construction of the foot must be seen as a compromise between the static and dynamic demands made upon it. In this article the structure and function of the ankle joint are described with special reference to the formation of morphological parameters such as the distribution of subchondral mineralization, cartilage thickness, subarticular cancellous bone and mechanical properties. These parameters could be seen as a biological reflection of the individual mechanical conditions.
