Articular Surface For The Cuboid Bone Of The Calcaneus In Anterior View

Description

Calcaneus anatomy is centered on the anterior articular surface for the cuboid, forming the calcaneocuboid component of the transverse tarsal (Chopart) joint. From this fixed anterior perspective, the saddle-shaped facet occupies the anterolateral calcaneus, with its concavity and convexity oriented to match the reciprocal contour of the cuboid’s posterior articular surface. Medial to the facet, the anterior process transitions toward the talar articular surfaces and the calcaneal sulcus region, while inferiorly the plantar aspect sweeps toward the tuber calcanei and the attachment zone for the long plantar ligament. Edges of the articular cartilage boundary are sharply defined. A reliable landmark. The calcaneocuboid joint acts as a key constraint on the lateral column, so small changes in facet congruity translate into painful midfoot loading and peroneal tendon overuse. Post-traumatic subtalar and calcaneal fractures can extend anteriorly and disrupt this facet, and surgeons assessing lateral-wall blowout or planning calcaneal osteotomy often need a precise sense of the calcaneocuboid relationship to avoid iatrogenic joint violation. Oblique lighting and isolated bony context in this illustration make the saddle geometry and rim transitions easy to teach without distraction from adjacent tarsals. Use this illustration in gross anatomy and lower-limb osteology modules to anchor discussion of the midtarsal joint line and lateral column biomechanics, or in orthopaedic and podiatry teaching materials covering calcaneocuboid arthritis, cuboid impaction fractures, and lateral column lengthening (Evans-type) planning. It also fits well in surgical atlases when explaining why lateral calcaneal approaches must respect the anterior process and calcaneocuboid articular margin.
