The systems reported in the literature tend to. High-impact injuries usually due to greater en-ergy forces such as those experienced during motor vehicle collisions are termed Lisfranc fracture-displacements. A homolateral injury is a lateral displacement of the 1 st to 5 th metatarsals or of 2 nd to 5 th.
In 1982 Hardcastle et al 4 modified this classification and denoted three basic types of injury. Type A complete homolateral dislocation Type B1 partial injury medial column dislocation Type B2 partial injury lateral column dislocation. Your foot will likely also be unable to bear weight.

Recently the introduction of a fourth category to the Myerson-modified Hardcastle classification has been proposed which corresponds to the so-called subtle injury of the Lisfranc joint or lesion type D15It is subdivided into D1 distance from the first cuneiform bone c1 to the second metatarsal m2 c1-m2 2 mm does not require surgical fixation. Lisfranc midfoot injuries result if bones in the midfoot are broken or ligaments that support the midfoot are torn.
It can range from mild to severe. Weightbearing radiographs and bone scintigrams were used to diagnose midfoot sprains in 15 athletes who were treated surgically or nonoperatively according to the following classification.

Mechanisms of injury that occur at this articulation. A Lisfranc injury is often mistaken for a simple sprain especially if the injury is a result of a straightforward twist and fall. A divergent injury is a lateral dislocation of the 2 nd to 5 th metatarsals with medial dislocation of the 1.
