A Lisfranc injury is a type of foot injury that affects the midfoot, specifically the area where the metatarsal bones connect to the tarsal bones. This injury can occur due to a fall, a sports-related accident, or a car crash, leading to ligament tears or fractures in the bones of the foot. Symptoms often include pain, swelling, and difficulty walking. Diagnosis typically involves a physical examination and imaging tests like X-rays or MRIs. Treatment may vary from rest and immobilization to surgery, depending on the severity of the injury. Early intervention is crucial for proper healing and to prevent long-term complications.
