We divided the ligaments in different groups: tibiofibular ligaments, Bassett’s ligament, lateral collateral ligament complex (anterior talofibular ligament, calcaneofibular ligament, lateral talocalcaneal ligament, posterior talofibular ligament), medial collateral ligament complex, spring ligament, Chopart joint ligaments (bifurcate ligament, dorsal talonavicular ligament, lateral calcaneocuboid ligament, long and short plantar ligaments), Lisfranc ligaments, sinus tarsi ligaments. Our sample of donors were American and predominantly white. Use this knowledge as a base for structured reporting of the ankle and midfoot (ligaments). The clinical ultrasound findings were consistent with an avulsion fracture of the superior dorsal cuboid associated with bifurcate ligament injury, later confirmed on MRI. Ultrasound Examination Technique Table 8.1 is a checklist for ankle, calf, and forefoot ultrasound examination. A probable reason for this is that the morphological characteristics of this structure have yet to be sufficiently elucidated. It connects the navicular bone’s plantar (foot side) surface with the sustentaculum of the calcaneus, a shelf-like side of the heel bone.
