Lisfranc (midfoot) injuries result if bones in the mid-foot are broken or ligaments that support the midfoot are torn. The severity of the injury can vary from simple to complex, involving many joints and bones in the mid-foot.
A Lisfranc injury is often mistaken for a simple sprain, especially if the injury is a result of a straightforward twist and fall. However, injury to the Lisfranc joint is not a simple sprain that should be simply "walked off."
It is a severe injury that may take many months to heal and may require surgery to treat.
