Ankle Anatomy
Many different motions or incidents can cause an ankle fracture to occur. Some of the most
common ways include twisting or rotating your ankle, tripping or falling, and impact during an
accident. When you fracture your ankle it is common for you to experience immediate severe
pain, swelling, bruising, an inability to put any weight on the injured foot and sometimes, a
noticeable deformity becomes present.
Causes and Symptoms
The ankle joint consists of three bones known as the tibia, fibula, and talus. The tibia and fibula
consist of the medial, posterior, and lateral malleolus. There are two different joints involved
when an ankle fracture occurs: the ankle joint, where the three bones of the ankle meet; or the
syndesmosis joint, the joint between the tibia and fibula that is held together with ligaments. The
ankle joint is important in three vital movements: plantar flexion, moving the foot downward
away from body; dorsiflexion, backward bending of the foot; and inversion turning the foot from
side to side and; eversion movements, turning the foot side to side inward and outward. The
ankle joint also works at absorbing shock as the heel strikes the ground when walking and/or
running.
