Getting a Diagnosis
Because a Lisfranc joint injury can mimic other problems that can occur with the foot (including sprains), it’s important to get a clear diagnosis from a foot and ankle specialist. Along with taking your medical history, your physician will perform a physical exam and check your symptoms.
Because the causes and symptoms that are associated with Lisfranc joint injury are the same as for a basic sprain, your medical care provider may request imaging tests to make a proper diagnosis. An x-ray is most commonly used because it can determine if there are any breaks in the bones. X-rays can also detect ligament issues based on widening between specific bones in the foot.
While an MRI or CT scan are not necessary, your physician may use one of these imaging tools to determine the exact position and severity of an injury to the Lisfranc joint complex.
