Anterior Facet For Calcaneus Of The Talus, Lateral View

Description

Talus anatomy at the talar head is the focus in this lateral view, centering on the anterior calcaneal facet, the small, smooth articular surface that participates in the anterior portion of the subtalar (talocalcaneal) complex. From this fixed perspective, the facet lies on the inferior aspect of the talar head and neck region, anterior to the more posterior talar body and oriented toward the superior surface of the calcaneus. The lateral contour of the head transitions anteriorly toward the talonavicular articular surface, while the inferior edge defines the boundary between the talar head’s plantar surface and the neck. Small area, big consequences. Understanding the anterior calcaneal facet matters when teaching how the subtalar joint is functionally partitioned into anterior and posterior components, with the anterior facet often discussed alongside the middle facet and the sustentaculum tali region of the calcaneus. In symptomatic talocalcaneal coalition, arthrosis, or post-traumatic subtalar pain, learners often struggle to localize which talar and calcaneal articular regions are implicated, and this lateral orientation makes the head-based facet easier to isolate than a superior view that visually competes with the trochlea tali. Orthopaedic discussions of talar neck fractures, lateral process injuries, and sinus tarsi region approaches benefit from a clear appreciation of where the talar head’s inferior articular surfaces begin relative to the neck. Use this illustration for lower limb anatomy modules covering the tarsal bones, subtalar joint surface anatomy, and osteology practicals that test identification of talar facets by location and relationship. It also fits well in foot and ankle surgery atlases or lecture slides when explaining subtalar arthroscopy portals, coalition workup, or planning around articular cartilage preservation at the talar head.
