An avulsion fracture of the ankle (a small fleck of bone seen on radiographs just distal to a malleolus)  is an ankle sprain equivalent.  The primary injury is to the ligament, not the bone. The fleck seen is a fragment tugged off the bone when the calcaneofibular ligament was pulled, much like a Just as a piece of masking tape yanked briskly from a wall may take with it a sliver of paint as well.
