here's bit more general info that I found interesting:


Frontal film of the foot shows fracture dislocation in the tarsometatarsal joint (Lisfranc's joint) with homolateral dislocation of first through fifth metatarsals and dorsolateral total incongruity (Myerson Type A).

Jacques Lisfranc (1790-1847) was a field surgeon in Napoleon's army serving on the Russian front. He wrote about a new amputation technique to treat forefoot gangrene from frostbite. This technique involved a route following a series of joints to avoid having to take the time to cut through bone. This route became known as the Lisfranc joint. However, Lisfranc did not actually describe the injury pattern well known by this eponym.

A Lisfranc injury encompasses everything from a sprain to a complete disruption of normal anatomy through these joints. Early recognition and treatment of this injury are important to preserve normal foot function.

The Lisfranc joint line describes the anatomic boundary between the rigid midfoot and the suppler weightbearing forefoot. Instability or disruption of normal support can lead to significant pain and disability for normal ambulation.

The incidence of this uncommon injury is approximately 1 per 55,000 persons per year.

Indirect trauma is more common than direct. Violent abduction of the forefoot can lead to lateral displacement of the four lateral metatarsal bones with or without a fracture at the base of the second metatarsal bone and the cuboid.
Dorsal displacement is more common than plantar. First metatarsal bone may dislocate in the same or opposite direction of other metatarsals. The result is damage to the tight ligamentous structure of this joint complex, which creates an unstable foot for weightbearing

Additionally this was an interesting comment on another surgical approach to this condition:

Reduction of a fracture-dislocation of Lisfranc's joint by endoprosthetic implantation.

Sharon SM, Knudsen HA, Lowhorn M.

The medical literature demonstrates numerous documented cases of post-traumatic arthrosis following comminuted fracture-dislocations at the tarsometatarsal joint(s). Conventionally described reductions and methods of fixation, therefore, lend themselves to less than acceptable results. A newly devised, alternative method of approach to this disabling injury was indicated, and is presented by the authors in the hope of preventing the long-term sequelae commonly seen with this type of injury. After open reduction and remodeling of a severely comminuted fracture-dislocation at the second metatarsal-cuneiform articulation, a modified, double-stemmed Swanson Silastic implant was utilized in order to maintain second ray length and attempt prevention of the usual postinjury osseous consequences, i.e., fusion and arthritic changes. The case presented demonstrates that, after her last clinical evaluation 19 months postoperatively, the patient returned to her normal occupation, and at that time her foot was normal in appearance with no sign of traumatic arthritic change. This procedure thus far has proved to be very rewarding to the patient, and the authors believe it should be considered as an alternative approach in patients who present with injuries of this magnitude.
