Neck Of The Talus, Lateral View

Description

Talus anatomy dominates the lateral ankle in this image, with the rough, narrowed neck positioned anterior to the talar body and posterior to the rounded head. From the fixed lateral perspective, the talar dome (trochlea tali) rises superiorly for articulation with the distal tibia, while the head projects anteromedially toward the navicular, separated from the body by the slightly constricted neck. Inferior to the neck, the lateral aspect of the subtalar articular surface and the opening into the sinus tarsi region are suggested by the contour changes between the talus and adjacent tarsal spaces. No movement implied. Talar neck morphology matters because it is the classic fracture site in high-energy dorsiflexion injuries, and small shifts in alignment can disrupt both the tibiotalar and subtalar joints while jeopardizing intraosseous blood supply. The lateral view is the one you reach for when teaching why Hawkins type II to IV talar neck fractures carry increasing risk of avascular necrosis, given the retrograde perfusion from the artery of the tarsal canal and contributions from the dorsalis pedis and peroneal branches. Surface roughness and the subtle narrowing of the neck help orient screw trajectories for open reduction and internal fixation while keeping hardware away from the talar dome cartilage. A tight corridor. Use this illustration in orthopedic trauma and podiatric surgery teaching files, in anatomy lab manuals covering the tarsal bones, and in radiology or CT correlation figures where the lateral talus outline must match what trainees see on a lateral ankle projection. It also suits publisher layouts on ankle fractures, subtalar joint congruity, and post-traumatic osteoarthritis. Anatomical accuracy verified by SciePro's Medical Advisory Board.
