Relating to or connecting the heel bone (calcaneus) and the smaller bone of the lower leg (fibula), often used in anatomy to describe ligaments.
From Latin 'calcaneus' (heel bone) + 'fibula' (clasp or pin-shaped bone). The fibula was named for its pin-like shape by Roman anatomists. Medical terminology combined these terms to describe structures spanning between these two bones.
Your ankle's calcaneofibular ligament is literally a superhighway for injury—it's the most commonly sprained ligament in the human body because it has to handle all the twisting forces when you step wrong!
