What type of injury is a Lisfranc injury?

A Lisfranc injury specifically refers to damage that occurs at the Lisfranc joint complex, which is located in the midfoot. This complex includes the tarsometatarsal joints connecting the midfoot bones (tarsals) to the metatarsals of the toes. Such an injury can involve fractures, dislocations, or both, and it often results from high-impact trauma, such as a fall or a vehicle accident, where excessive force is applied to the foot.

Recognizing the injury as related to the Lisfranc joint is essential because it guides the management and treatment strategy. These injuries can lead to significant complications if not treated appropriately, as they can affect foot stability and function. Accurate diagnosis is crucial, often requiring imaging studies like X-rays or MRIs to assess the extent of the injury, and treatment can range from conservative management to surgical intervention, depending on the severity.
