A Lisfranc injury refers to damage to the midfoot, specifically affecting the Lisfranc joint complex. This area includes the bones and ligaments that connect the forefoot to the midfoot. Such injuries can occur from direct trauma, like a fall, or from twisting motions, often seen in sports. Symptoms of a Lisfranc injury include pain, swelling, and difficulty bearing weight on the affected foot. Diagnosis typically involves physical examination and imaging tests, such as X-rays or MRIs. Treatment may range from rest and immobilization to surgical intervention, depending on the severity of the injury.
