Answer 4.
Lis franc’s ligament – strong oblique ligament which extends from plantar-lateral aspect of medial cuneiform, passes in front of the intercuneiform ligament, and inserts into the plantar-medial of second metatarsal – variations:
- in about 20% of patients, two separate bands of the ligament are present (dorsal and plantar);
- in patients with two separate ligamentous bands, partial ligament injuries are possible;
- function:
- acts to connect lateral metatarsals to the medial cuneiform;
- reinforces bony stability of base of the 2nd metatarsal between medial and lateral cuneiforms.
