Imaging Studies

Plain radiography, bone scanning, and computed tomography (CT) scanning findings are usually normal. Plain radiographs may show an enlarged posterior tubercle of the talus or an os trigonum in patients with posterior ankle impingement.[11, 13]  Having the patient adopt a lunge position that reproduces their pain may show bone-on-bone impingement on a plain radiograph. Patients with anterior ankle impingement may show tibial and talar spurring.

Magnetic resonance imaging (MRI) is the imaging technique of choice because of its advantage in identifying osseous and soft-tissue abnormalities.

Stress radiography findings are usually negative, and this study is not indicated.

Ultrasound may be useful in identifying some synovitic lesions, especially within the anterolateral gutter.[14]
