What is a Lisfranc Injury? | Causes, X-rays & Treatment Simplified

In this video, we review Lisfranc fracture-dislocations, one of the most important midfoot injuries, based on Netter’s Concise Orthopaedic Anatomy. These injuries involve the tarsometatarsal (TMT) joint complex, critical for foot stability and load transmission. Mechanism: typically torque of a fixed foot, axial load on a plantarflexed foot, or seemingly trivial trauma such as misstepping into a hole. The injury often involves fracture at the base of the 2nd metatarsal and instability between the metatarsals and cuneiforms. Classification by direction: Isolated: only one or two metatarsals displaced. Homolateral: all metatarsals dislocated in the same direction. Divergent: metatarsals displaced in different directions. Dorsolateral dislocation: best seen on lateral view, often associated with fractures.
