In order to exclude an ankle fracture, an X-ray of the ankle joint is recommended. This is especially recommended in the case of severe pain and massive swelling and the inability to load the limb in the three-step test. Ankle ultrasound should be performed in every case of ankle sprain to assess the efficiency of the damaged ligaments and to exclude the presence of complications in the pathology of other soft tissues.

Ankle ultrasound examination is a non-invasive imaging examination using ultrasound waves. During the ultrasound examination, the radiologist or orthopedist applies a special head to the ankle, first applying a coupling gel to the skin of the examined area. All soft tissues surrounding the ankle (ligaments, muscle tendons, straps, nerves, blood vessels) are assessed. Ultrasound images also show the synovium and the contours of the anterior part of the Talus. During the so-called dynamic ultrasound examination, the doctor performs special tests to assess selected structures (e.g. the efficiency of ligaments). It may also ask you to tighten a muscle or make a specific movement with your foot.
