A Lisfranc injury is a type of foot injury that affects the midfoot, specifically the Lisfranc joint complex. This area consists of several bones and ligaments that connect the forefoot to the midfoot. The injury can occur due to a direct impact, such as a fall or a sports-related accident, or from twisting the foot in an awkward position. Symptoms of a Lisfranc injury often include pain, swelling, and difficulty walking. Diagnosis typically involves physical examination and imaging tests like X-rays or MRIs. Treatment may range from rest and immobilization to surgery, depending on the severity of the injury.
