Posterior Process Of The Talus In Inferior View

Description

Seen from the plantar (inferior) aspect, the talus is oriented with the trochlea superior and the posterior process projecting posteriorly from the body of the bone. The animation centers on the paired posterior tubercles, the larger lateral tubercle and smaller medial tubercle, separated by the sulcus for the flexor hallucis longus tendon. As the camera holds the inferior viewpoint and subtly rotates, the groove’s course relative to the posteroinferior talar surface and adjacent subtalar articular area becomes easy to track. Bony relief reads clearly. Posterior ankle pain can hinge on millimeters at this site, where an elongated lateral tubercle (Stieda process) or a separate os trigonum may contribute to posterior ankle impingement during forced plantarflexion in dancers and footballers. The flexor hallucis longus tendon glides through the sulcus, so hypertrophy, tenosynovitis, or a prominent posterior process can produce triggering or pain with hallux motion and push-off. A sequential animation helps by showing the posterior tubercles and tendon groove from a fixed inferior reference while the bone rotates, reinforcing how surgical landmarks shift with viewing angle during hindfoot endoscopy or a posterolateral approach. Use this clip in gross anatomy and osteology teaching for the tarsal bones, in radiology correlation for lateral ankle and hindfoot CT/MRI where os trigonum versus fracture of the lateral tubercle is a common read, and in sports medicine content covering posterior impingement and FHL tendinopathy.
