Dorsal calcaneocuboid ligament
Ligamentum calcaneocuboideum dorsale
- Synonym: Laterodorsal calcaneocuboid ligament
Definition
The dorsal calcaneocuboid ligament (Laterodorsal calcaneocuboid ligament) is a a thin but broad distinct capsular ligament located on the laterodorsal aspect of the calcaneocuboid joint. It consistently spans from the dorsal surface of the calcaneus to the dorsal surface of the cuboid, forming a stabilizing structure for the lateral column of the foot.
This ligament is present in all specimens, either as a solitary band or as two components (superior and inferior), with the solitary form being more common. The ligament typically measures approximately 18–19 mm in length and 12–14 mm in width, with some variation depending on whether it is single or bifurcated.
The fibers of the dorsal calcaneocuboid ligament run in an upward and slightly lateral direction, fanning out from the calcaneal origin to the cuboid insertion. It lies superficial to the bifurcate ligament and is separated from the extensor digitorum brevis muscle by a thin layer of connective tissue.
