A<unk> , also known as a syndesmotic ankle<unk>  (SAS), is a<unk>  of the syndesmotic ligaments that connect the tibia and fibula in the lower leg, thereby creating a mortise and tenon joint for the ankle.<unk> s are described as<unk>  because they are located above the ankle. They comprise approximately 15% of all ankle<unk> s. Unlike the common lateral ankle<unk> s, when ligaments around the ankle are injured through an inward twisting,<unk> s are caused when the lower leg and foot externally rotates (twists out).
