Cuboid-Metatarsal Ligaments

ligamenta cuboidea-metatarsalia

The cuboid-metatarsal ligaments connect the cuboid to the fourth and fifth metatarsal bases, providing the dorsal, plantar, and interosseous constraints of the lateral TMT joints.

Region: Foot & Ankle
Biomechanics

Function & Actions

Stabilise the fourth and fifth TMT joints, allow the increased mobility of the lateral column for terrain adaptation, and resist excessive dorsal or plantar displacement of the lateral metatarsals.

Clinical Relevance

Clinical Notes

Cuboid-metatarsal ligament disruption in lateral column Lisfranc injuries requires assessment — isolated lateral column instability (fourth and fifth TMT) may be managed with closed reduction and casting while medial column injuries generally require surgical fixation.

Pathology

Common Injuries & Conditions

Lateral Column Lisfranc Injury

Fourth and fifth TMT ligament disruption as the lateral component of Lisfranc injury, managed by reduction and fixation when associated with medial column instability or when isolated instability persists after casting.
