Abstract:

Objective　Morphological measurements of Lisfranc ligament complex were made to provide anatomical basis for ligament reconstruction.　Methods　8 fresh adult cadaver foot specimens were dissected. The length, width and area of the ligaments between the medial cuneiform(C1) and second metatarsal base (M2), including dorsal ligament, plantar ligament and Lisfranc ligament, the distance from the articular surface of Lisfranc ligament, and the angle of Lisfranc ligament were measured and analyzed， respectively. According to the measurement results, bone tunnel between the first cuneiform and second metatarsal base was established.　Results　Lisfranc ligament was the largest among the three ligaments, The lengths,widths and area were (9.11~12.03 mm), (7.36~10.16 mm), (92.01~120.01 mm²)，respectively. Lisfranc bone tunnel: the entry point was (8.25~11.22 mm) from C2-M2 joint; the angle was consistent with the Lisfranc ligament course, which was (39.2°~47.6°) degrees to the sagittal plane and (12.5°~19.8°) degrees to horizontal plane;  the exit point was Lisfranc ligament origin of the first cuneiform.    Conclusion   Lisfranc is the most robust among the three ligaments. The bone tunnel of reconstruction is established for the formation of Lisfranc ligament and dorsal ligament in accordance with Lisfranc ligament angle and attachment. Since the position of plantar ligament is deep, the reconstruction is close to approximate anatomical reconstruction due to the technical limitations.
