As you can see, the anatomy of the ankle is very complex. When everything works together, the ankle functions correctly. When one part becomes damaged, it can affect every other part of the ankle and foot, leading to problems.
If the foot is forcibly plantarflexed, the talus (astragalus) glides forward out of its socket and produces a prominence which is most apparent in front of the lateral malleolus. The medial or internal malleolus is large, flat and prominent. The ankle joint lies approximately 1/2 inch above ...
The ankle joint is a complex of articulations between the distal ends of the tibia and its medial malleolus, lateral malleolus of the fibula, and the trochlear surface of the talus. All of the articular surfaces of the ankle joint are covered with hyaline cartilage. There are three articulation...
ANKLE ANATOMY & FUNCTION ∙Joint is formed by the tibia and fibula and the talus.∙Joint allows for the dorsiflexion (up) and plantarflexion (down).∙Tibia forms the medial malleolus (inner bony prominence). ∙The lateral malleolus (outer bony prominence) and is formed by the ...

ANATOMY The ankle joint is composed of the talus, which articulates with the ankle mortise (formed by the distal tibia, the lateral and medial malleolus). The three major groups of ligaments (deltoid, tibiofibular, tibiotalar) originate on an epiphysis (Fig. 16-1) and provide stability for...
Severe pain is felt when pressing over the medial or lateral malleolus, the bony bumpson each side of the ankle. There is a loss of feeling in the foot or toes. There is pain and swelling in the back of the ankle (heel pain), over the Achilles tendon area, or the inability to push...
