Dorsal Cuboideonavicular Ligament Anatomy, Operate & Diagram

The dorsal cuboideonavicular ligament, also referred to as the ligamentum cuboideonavicular dorsale or the dorsal ligament of the cuboideonavicular joint, is a brief band of fibers bundled collectively, though it’s typically synovial fairly than fibrous. It’s one in every of 5 dorsal tarsal ligaments positioned on the dorsum of the foot. The dorsal cuboideonavicular ligament connects the navicular and cuboid tarsus bones’ dorsal surfaces. Its fibers prolong transversely between the posterior a part of the cuboid bone’s medial adjoining border and the navicular bone’s rounded lateral border. It attaches proximally to the cuboid bone’s dorsum and distally to the navicular bone’s dorsum. The ligament’s fibrous bundle The dorsal cuboideonavicular ligament is triangular in form and has each a lateral base and a medial apex. It’s usually thought of a syndesmosis. Its perform is to assist the articular surfaces of the cuboideonavicular joint’s capsule, that are joined by robust fibrous interosseous ligaments. The dorsal cuboideonavicular ligament is usually changed by a synovial joint supported by the plantar and dorsal ligaments, and lined with a synovial membrane.
