Anterior talofibular ligament (ATFL) injuries can occur in three different distinct patterns; rupture of the ligament as a pure soft tissue injury, an avulsion fracture at the ATFL's attachment to either the fibula or the talus. Although fibular avulsion fractures are common, avulsion fracture of ATFL from talus is extremely rare with a single previously reported case in the current literature. ⋯ Besides more common injury patterns such as mid-substance ATFL rupture and ATFL fibular avulsion fracture, talar avulsion fracture pattern should also be kept in mind in a patient presented with lateral ankle sprain. When a fragment is seen on the ankle radiographs at the tip of fibula, previously described special oblique views should be performed to reveal the correct origin of the fragment.
