title: [Injury of the ankle joint ligaments].
abstract: The diagnosis of lateral collateral ankle ligament trauma is based on patient history, clinical examination and clinical stress tests. If the clinical stress test is positive, stress radiography can be performed. There is, however, no consensus about the usefulness of stress radiography in acute ankle sprain, and in particular about the cut-off talar tilt angle beyond which a two-ligament rupture would be certain, ranging from 5 degrees to 30 degrees. Today, magnetic resonance imaging (MRI) is not used in this area, although it does allow controlled positioning of the foot and defined section visualization of injured lateral collateral ankle ligaments. In acute and chronic sinus tarsi injuries, MRI forms the established basis for diagnostic imaging, and can provide a definitive answer in most cases. MRI is also the method of choice for chronic posttraumatic pain with anterolateral impingement after rupture of the anterior talofibular ligament. Generally, for the evaluation of acute ankle injuries, MRI has developed to be the most important second-step procedure when projection radiology is non-diagnostic.
