Ankle impingement syndromes refer to a chronic painful mechanical limitation of the ankle caused by soft tissue or osseous abnormalities. Posterior ankle impingement syndrome is a spectrum of clinical disorders characterized by posterior ankle pain during plantar flexion or hyper flexion. Posterior impingement syndrome is characterized by compression in the anatomic region between the posterior tibia and calcaneus during plantar flexion. It was described as “posterior block of the ankle joint" in a population of elite dancers. Also, it was termed “talar compression syndrome". MRI can demonstrate osseous and soft-tissue edema in anterior or posterior impingement. MRI is the most useful imaging modality in evaluating suspected soft-tissue impingement or in excluding other ankle pathology such as an osteochondral lesion of the talus. MRI can reveal evidence of previous ligamentous injury and also can demonstrate thickened synovium, fibrosis, or adjacent reactive soft-tissue edema.

AIM OF THE WORK:
The aim of this work was to evaluate the role of Magnetic Resonance Imaging in assessment of posterior ankle impingement syndrome.
