The ankle joint is a hinge joint that connects the lower leg bones (tibia and fibula) to the talus bone of the foot. It is stabilized by strong ligaments including the deltoid ligament medially and three ligaments laterally. The ankle allows for two motions: dorsiflexion which points the toes up and is controlled by the tibialis anterior muscle, and plantar flexion which points the toes down and is controlled by the gastrocnemius and soleus muscles. Common injuries include ankle sprains from excessive inversion or eversion stretching the ligaments, and Pott's fractures involving fractures of the medial and lateral malleoli.
