Orthopedics - The branch of medicine that deals with the prevention or correction of injuries or disorders of the skeletal system and associated muscles, joints, and ligaments.

In anatomy, the ankle, or ancle (a word common, in various forms, to Teutonic languages, probably connected in origin with the Latin angulus, or Greek αγκυλος, bent), is the part of the lower limb that is located between the foot and the leg, and is actually comprised of two separate joints: the talocrural joint (or "true" ankle joint) and the subtalar joint.
