Cuboideonavicular Ligament of the Male Foot, Dorsal View

Description

Positioned on the dorsal aspect of the midfoot, the cuboideonavicular ligament spans obliquely between the lateral surface of the navicular and the dorsomedial margin of the cuboid, bridging the interval just distal to the talonavicular joint and proximal to the bases of the fourth and fifth metatarsals. The cuboid lies lateral and slightly plantar relative to the navicular, while the talus sits proximal and medial, with the calcaneus proximal and lateral forming the calcaneocuboid component of the transverse tarsal (Chopart) joint. Adjacent dorsal bands of the intertarsal region, including dorsal talonavicular and dorsal calcaneocuboid capsular fibers, frame the ligament within the dorsal midfoot retinacular plane. Small. Consistent. Clinically, this is a useful dorsal reference for understanding stability across the lateral column and the congruity of the midtarsal joint complex during inversion and eversion. Sprain patterns after forced inversion can involve the calcaneocuboid and talonavicular capsules, and the cuboideonavicular ligament helps explain why pain can localize to the dorsolateral midfoot even when the primary injury centers on Chopart joint disruption. For surgeons, a clear depiction of this band clarifies the tissue planes encountered in dorsal approaches to the midfoot for reduction and fixation, and it supports interpretation of MRI findings when dorsal midfoot ligament edema tracks between cuboid and navicular. Educators will find this asset well suited for lower limb anatomy labs, podiatry and orthopedic teaching on intertarsal ligaments, and figure preparation for chapters on midfoot sprain, Chopart injuries, or lateral column mechanics. It also reads cleanly in patient-facing materials explaining dorsal midfoot pain after twisting injuries, where naming a specific ligament helps anchor the discussion.
