Answer

Plain radiographs should probably be obtained to exclude extrinsic factors (eg, exostoses, malunions, or osteochondromas) that cause direct compression of the posterior tibial nerve. In patients with posttraumatic symptoms, further investigation (eg, with computed tomography [CT] or magnetic resonance imaging [MRI]) can help identify occult sources of pain, such as medial talar process fractures, medial malleolus stress fractures, and space-occupying lesions.
