Ankle Joint Anatomy

• The ankle joint is formed by the articulation of the tibia, fibula, and talus bones.
• The medial malleolus of the tibia and the lateral malleolus of the fibula form the ankle joint.
• The process at the distal anterior and lateral tibia that articulates with the superolateral talus is called the medial malleolus.
• In a true lateral position, the distal fibula is posterior to the distal tibia.
• The deep 'socket' into which the superior talus fits is called the mortise.
• The ankle joint is a synovial hinge joint.
• The horizontal plane drawn through the midportions of the two malleoli is called the intermalleolar plane.
• A mortise view is needed to demonstrate the mortise of the ankle joint.
