Cuboid navicular tarsal coalition: Presentation and evaluation with emphasis on magnetic resonance imaging appearance

摘要

Tarsal coalition is an uncommon condition that is often overlooked in the adult population. The potential sequelae of untreated tarsal coalition include changes in gait mechanics, flattening of the longitudinal arch and degenerative changes in the hindfoot joints. Tarsal coalition should be considered as a possible diagnosis in the active younger patient who presents with frequent hindfoot pain and ankle sprains. Our report presents a case of an incidental finding of an asymptomatic cuboid-navicular tarsal coalition in a patient who presented with persistent Achilles tendinosis and reviews the available literature regarding this condition.
