Imaging tests. Imaging tests are the best way to confirm a diagnosis of a Lisfranc injury.
X-rays will show any broken bones, as well as the alignment of the Lisfranc joint complex. They may take X-ray images of the uninjured foot for comparison.
In some cases, CT scans or MRIs will be used. These tests provide a more detailed image of the foot than an X-rays, and are better for looking at softer tissues. They may be more common in cases that could involve surgery.
