Cuboid Articular Surface Of The Human Calcaneus, Medial View

Description

Calcaneus anatomy fills the frame from a medial viewpoint, with the anterior articular surface for the cuboid presented near the distal end of the bone and oriented anterolaterally toward the lateral column of the foot. The calcaneocuboid facet reads as a gently concave, saddle-like area, bordered superiorly by the calcaneal neck and inferiorly by the plantar contour that continues toward the tuberosity. Medial landmarks help with orientation, including the sustentaculum tali projecting medially above the midfoot region and the adjacent groove for the tendon of flexor hallucis longus on the inferior aspect of the sustentaculum. No soft tissues obscure the bony relief. That concavity matters when you teach or plan around the calcaneocuboid component of the transverse tarsal (Chopart) joint, where joint congruence and lateral column length influence midfoot stability and forefoot abduction. Post-traumatic deformity after calcaneal fractures can subtly alter the calcaneocuboid articular surface, and clinicians often correlate this with lateral midfoot pain, early osteoarthrosis, or difficulty restoring hindfoot alignment during reconstruction. The medial perspective helps clarify how far anterior the cuboid facet sits relative to the sustentaculum and how the articular margin transitions into nonarticular cortical bone. A small surface, big consequences. Use this illustration in gross anatomy and podiatry teaching to anchor discussions of the calcaneocuboid joint, in orthopedic or radiology publications describing Chopart joint injury patterns, or in surgical education when outlining lateral column reconstruction and arthrodesis targets.
