MRI of ankle and lateral hindfoot impingement syndromes.
OBJECTIVE
The objective of this article is to review the pathophysiology and clinical presentation of impingement syndromes at the ankle joint (anterolateral, anterior, anteromedial, posteromedial, and posterior) and the role of MRI in evaluating impingement at the ankle joint and at extraarticular locations, lateral to the ankle joint (talocalcaneal and calcaneofibular).


CONCLUSIONS
MRI is valuable in assessing both osseous and soft-tissue abnormalities associated with impingement syndromes.
