Dorsal Calcaneocuboid Ligament in a Male Foot

Description

Seen from a lateral dorsal angle, the calcaneus lies posterior to the cuboid, with the dorsal calcaneocuboid ligament spanning the dorsolateral aspect of the calcaneocuboid joint as short, stout bands blending with the joint capsule. Superior to this midfoot articulation, the distal tibia and fibula frame the talocrural joint, while the talus sits anteroinferior to the tibia and articulates inferiorly with the calcaneus at the subtalar joint. Distal to the cuboid, the bases of the lateral metatarsals extend anteriorly, establishing the line of load transfer toward the forefoot. Bony landmarks remain crisp. Functionally, the dorsal calcaneocuboid ligament is a key dorsal restraint within the transverse tarsal (Chopart’s) joint complex, countering dorsal gapping of the calcaneocuboid joint during midstance and toe-off as the lateral column shifts from mobile adaptor to rigid lever. Lateral midfoot sprains can injure this capsuloligamentous complex, and disruption contributes to calcaneocuboid instability and post-traumatic arthrosis, a pattern sometimes missed when attention stays on the ankle mortise. The relationship to the peroneus longus tendon as it courses plantarward around the cuboid groove is also instructive when discussing lateral column pain and surgical exposures that approach the calcaneocuboid joint between extensor tendons on the dorsolateral foot. Use this asset for gross anatomy lab teaching on the tarsal joints, for orthopedic and sports medicine modules on Chopart injuries, and for atlas or journal figures discussing lateral column stabilization, dorsal midfoot capsuloligamentous repair, or arthrodesis planning at the calcaneocuboid joint. It also reads well beside radiographs or CT in lateral projections when labeling dorsal ligaments versus capsule. Anatomical accuracy verified by SciePro's Medical Advisory Board.
