The «Lisfranc», represents an articular interline connecting the middle foot and the bases of the metatarsal bones. In addition to the joints, there are many ligament junctions to ensure stability between this “medius foot” and the forefoot. Lisfranc’s anatomical ligament links the 1st cuneiform (median bone upstream of the 1st metatarsal), to the base of the 2nd metatarsal.
The sprain requires the use of a walking boot, with or without support for a period of 6 weeks, combined with frosting, raising, proprioceptive work, and physiotherapy.
Dislocation occurs in cases of more severe trauma, and often involves transient pin fixation (arthrorise), associated with ankle immobilization.
