Classification of the inferior fascicle of the anterior inferior tibiofibular ligament, right side, anterolateral. 1: Anterior inferior tibiofibular ligament, 2: Inferior fascicle of the anterior inferior tibiofibular ligament, 3: Anterior talofibular ligament, 4: Fibula, L: Lateral, M: Medial. Type I: Distinct inferior fascicle is separated from the rest of the ligament. The inferior fascicle is separated completely from the main portion of the ligament by a gap. Type II: Distinct inferior fascicle with either its proximal or its distal attachment continuous with the rest of the ligament. A gap does not completely separate the inferior fascicle from the rest of the ligament. Type III: Lower portion of the ligament includes the inferior fascicle with the attachments to the rest of the ligament. Type IV: Ligament with no separations or gaps within its structure. It may or may not have a fascicular arrangement.
