Abstract:

BACKGROUND: Lisfranc ligament is the strongest one among three ligaments between the second metatarsal bone and the medial cuneiform, and it is critical for maintaining the stability between the second metatarsal bone and the medial cuneiform because Lisfranc ligament is three times stronger than the dorsal ligament. However, there have been no reports addressing the effects of Lisfranc ligament injury on the stability of tarsometatarsal joints.
METHODS/DESIGN: An anatomical and biomechanical study was performed. Anatomical measurements were performed in the origin, terminal, path, length, width, and thickness of Lisfranc ligament utilizing cadaverous embalmed specimens. In the experiment on fresh-frozen cadaveric specimens, the displacement changes between the first and the second metatarsal base under different loading were measured with biomechanical analysis after the successively resected dorsal ligament, Lisfranc ligament, and plantar ligament were loaded, respectively, exploring the effect of Lisfranc ligament on stability of tarsometatarsal joints.
DISCUSSION: This study provides the theoretical basis for the treatment of tarsometatarsal joint injury in the clinic through exploring the effects of Lisfranc ligament on stability of tarsometatarsal joints. The attention should be paid to Lisfranc ligament by the physicians when the tarsometatarsal joint injury occurs.
