Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - The ankle is a hinge joint with the talus sitting in the mortise formed by the distal tibia and distal fibula. Ankle dislocations require forces of great magnitude. Posterior and lateral dislocations are most common, but the ankle can also dislocate medially, superiorly, or anteriorly. A posteriorly dislocated ankle is locked in plantar flexion with the anterior tibia easily palpable. The foot has a shortened appearance with an edematous ankle. Anterior dislocations present with the foot dorsiflexed and elongated. Lateral dislocations present with the entire foot displaced laterally. Ankle dislocations are frequently associated with fractures and may be open. SN - PB - McGraw-Hill CY - New York, NY Y2 - 2024/11/09 UR - accessmedicine.mhmedical.com/content.aspx?aid=1181488523 ER -
