Posterior-ankle impingement (PAI) syndrome describes a group of pathological entities that result from repetitive plantar flexion of the foot that causes repeated compression and entrapment of soft tissues, bony processes or unfused ossicles between the posterior-tibial plafond and the superior surface of the calcaneum. Ankle Impingement Overview Clinical DX Increasingly recognized cause of chronic ankle pain Etiology can be soft tissue or osseous Professional and amateur athletes Painful limitation of the full range of ankle movement ANTEROLATERAL ANTERIOR ANTEROMEDIAL POSTERIOR 3 Imaging of Ankle Impingement Conventional Radiography Osseous abnormalities. Posterior ankle impingement (PAI) is an umbrella term for a collection of pathologies that cause posterior ankle pain with ankle plantarflexion (pointing the toes downwards). Anterior ankle arthroscopy: state of the art. PURPOSE: To determine the accuracy of magnetic resonance (MR) arthrography in assessing the anterolateral recess of the ankle. -, Knee Surg Sports Traumatol Arthrosc. All underwent clinical examination and were included if anterolateral impingement ( n = 13) or a control condition ( n = 19; suspected osteochondral defect, intraarticular bodies, instability, osteoarthritis) was diagnosed. 18, No. 32, No. . J Clin Orthop Trauma. Supination injury of the ankle is one of the most common injuries in the general population and elite athletes. doi: 10.1016/j.mric.2009.06.006.

Mild posteromedial synovitis was present in two control athletes. 12, Clinics in Podiatric Medicine and Surgery, Vol. Results: Posteromedial capsular thickening was seen only in athletes with posteromedial impingement (7/9).

Ankle: Anterolateral Gutter Impingement Clinical: 50-year-old female with history of injury and subsequent persistent ankle pain and locking. 15, No. 4, Journal of Magnetic Resonance Imaging, Vol. 1, European Journal of Orthopaedic Surgery & Traumatology, Vol. It is classically described in ballet dancers. MR arthrographic findings were correlated with subsequent arthroscopic appearances. the plate must be limited to what surface of the radius to avoid impingement on the proximal ulna? 43, No. 17, No. 19, No. doi: 10.1016/j.eats.2015.03.012. Posterior ankle impingement should always be included in the differential diagnosis when evaluating a patient with chronic, deep posterior ankle pain, particularly in the very active patient or in a patient with a previous ankle injury.
