Another type of ankle sprain is the stretching of the ligament on the inside of the ankle. This ligament known as the deltoid ligament prevents the ankle from rolling out (eversion). Medial ankle sprains are not very common because this is a very thick, strong ligament.igaments prevent abnormal movement and promote joint stability. There are ligaments surrounding the ankle to prevent it from rolling in or out. There are not, however, any ligaments to limit plantarflexion (bending the foot and toes away from you) as they are normal and necessary movements.
