Anterior Talofibular Ligament Abnormality on Routine Magnetic Resonance Imaging of the Ankle

The anterior talo­fibular ligament (ATFL) extends from the anteroinferior border of the ­fibula to the talar neck. Primary restraint to ankle inversion in plantar‑exion. Injury (acute or chronic) can be diagnosed with physical exam, stress X-Rays, ultrasound or magnetic resonance imaging (MRI). Purpose: MRI abnormalities in asymptomatic individuals known in other areas of orthopaedics (shoulder and spine). Purpose of our study: determine the prevalence of ATFL abnormalities found on MRI in asymptomatic individuals. Asymptomatic individuals - those undergoing MRI for pathology unrelated to lateral ankle trauma, instability, or inversion injuries
