Tarsometatarsal Joint
From WikiSM
Description
Lisfranc joint cross section with the dorsal, interosseous, and plantar oblique ligaments[1]
- Alternative Names
- Lisfranc Joint
- Tarsal-metatarsal Joint
- Proximal Bones
- All 3 cuneiforms and cuboid
- Distal Bones
- Metatarsals 1 through 5
- Second metatarsal is keystone between medial, lateral cuneiforms
- 3 columns of the midfoot[2]
- Medial column: articulation between the first metatarsal and the medial cuneiform
- Middle column: 2nd, 3rd metatarsals articulation with the middle, lateral cuneiforms
- Lateral column: 4th, 5th metatarsals articulation with the cuboid
- Lisfranc ligamentous complex
- Intermetatarsal interosseous ligaments
- Strongest of the ligaments structures
- There is no intermetarsal ligament between the first and second metatarsal bases
- Thin dorsal ligaments connect the second, third, fourth and fifth metatarsals.
- Lisfranc ligament
- “Y” shaped interosseous ligament is the main stabilizer
- Plantar structure extends from the lateral aspect of the medial cuneiform to the medial aspect of the second metatarsal base.
- The strength of this ligament is such that its disruption will lead to altered stability within the medial and middle columns of the foot.
- Intermetatarsal interosseous ligaments
