ABSTRACT
The ankle joint is a remarkable example of the functional interplay between bones, joints, and ligamentous structures, with their protective action upon one another. The ankle joint is maintained by the wedge-shaped talus and its sculptured fit between the tibia and fibula. In the neutral position of the ankle, there are strong osseous (bony) constraints. With increasing plantar flexion, the osseous constraints decrease and the soft
tissues and ligaments maintain the joint stability. It is in this position that the ligamentous tissues are most susceptible to injury.
