The Ankle Joint

The ankle joint is a synovial hinge joint located in the lower limb.  It is formed by the bones of the leg, the tibia and fibula, and the talus of the foot.  The tibia and fibula are bound together by strong ligaments and together they form a bracket shaped socket known as a mortise.  The body of the talus in the foot fits snugly into the mortise, forming the ankle joint.
