Ankle impingement is a bony growth at either the front or back of the ankle bone where it meets the shin bone. It is also known as Anterior Impingement (front) and Posterior Impingement (back).
Tissues in the ankle joint can become trapped between bones in the ankle. This is known as impingement and occurs when the ankle is bent fully up or down. Posterior impingement in the back of the ankle is more common in ballet dancers and can be due to a bony protrusion at the back of the ankle.
Anterior impingement (at the front of the ankle) can occur from a bad or repeated ankle sprain as the ligaments thicken and get pinched between the bones (tibia and talus bone). As the torn or ruptured ligament heals, the body forms too much scar tissue along the front and round the side of the ankle joint creating a meniscoid lesion.
