39. eversion injuries : Pott's fracture
The medial and lateral ligaments of the ankle. (A) The medial (deltoid) ligament is quite strong, binding
the tibia to 3 bones. the calcaneus, navicular, and talus. (B) In a twisting injury. involving eversion of the foot. the
strong deltoid ligament might not tear but instead pulls off the medial malleolus and forces a fracture of the
fibula (Pott's fracture). (C) The relatively weak lateral ligament is commonly injured. particularly with inversion injuries. where it may tear (ankle sprain) and/or tear off the lateral malleolus.
