Anterior Process Of The Calcaneus, Anterior View

Description

Anterior process of the calcaneus projects forward from the anterolateral aspect of the heel bone, forming the anterior margin of the calcaneus in this frontal perspective. The smooth articular surface for the cuboid (facies articularis cuboidea) occupies the distal face, with its contour curving from superolateral toward inferomedial as it approaches the plantar border. Medial to this projection, the body of the calcaneus broadens toward the sustentaculum tali region, while laterally the anterior process blends into the region adjacent to the sinus tarsi. Bone relief is crisp. Anterior process anatomy matters because small fractures here are common after inversion injuries and are routinely mistaken for lateral ankle sprains on first presentation. The lesion sits at the junction of the calcaneocuboid joint and the bifurcate ligament attachments, so tenderness can localize just distal and anterior to the lateral malleolus, and joint surface involvement may drive decisions about immobilization versus operative fixation. A fixed anterior view also helps when teaching why calcaneocuboid incongruity can produce persistent lateral midfoot pain and why oblique radiographs or CT often outperform standard ankle series for detection. Use this illustration in gross anatomy and osteology labs to orient learners to the tarsal relationships between calcaneus and cuboid, and in sports medicine or emergency medicine teaching materials that cover anterior process fractures and lateral midfoot injury patterns. It also fits well in orthopedic and podiatric publications discussing calcaneocuboid arthrodesis planning, bifurcate ligament injury, and surgical approaches that respect the anterior process as a landmark.
