The method for measuring the morphological characteristics of the Lisfranc ligament and the cuneiform 1-metatarsal 2&3 plantar ligament. a: The measurement site of the fiber bundle length at articular surface of the first cuneiform and the second metatarsal in the Lisfranc joint. b: The measurement site of the fiber bundle width at articular surface of the first cuneiform and the second metatarsal in the Lisfranc joint. c: Dorsal view of the right foot. d: The method for measuring fiber bundle angle of the ligament at articular surface of the first cuneiform and the second metatarsal in the Lisfranc joint. Line 1: the long axis of the first metatarsal (line connecting the midpoints of the width of the distal and proximal joint surfaces). Line 1′: Line projected onto Line 1 on the articular surface of the first cuneiform in the Lisfranc joint. Line 2: Central portion of the fiber bundle of the Lisfranc ligament. Line 3: Central portion of the fiber bundle of the cuneiform 1-metatarsal 2&3 plantar ligament . 1: the superior fiber bundle of the Lisfranc ligament, 2: the inferior fiber bundle of the Lisfranc ligament, 3: the cuneiform 1-metatarsal 2&3 plantar ligament, 4: Lisfranc ligament, L: lateral, M: medial, C1: first cuneiform, M1: first metatarsal, M2: second metatarsal
