Lisfranc Fracture-Dislocation

Napoleon’s surgeon Lisfranc’s name is given to this fracture-dislocation of the midfoot.

Lisfranc injuries are of 2 types:

1. Homolateral (shown): lateral dislocation of metatarsals 1-5 or 2-5.

2. Divergent: lateral dislocation of metatarsals 2-5 and medial dislocation of the first metatarsal.

Cuniform and base of metatarsal fractures are often associated.

Commonest contemporary causes are:

1. Road traffic accident
2. Diabetes – a manifestation of a neuropathic joint (this case)
