Painful Os Talus Secundarius: A Case Report and Imaging Findings

The os talus secundarius is a rare skeletal variant of the ankle, and the most recent report of this entity in the medical literature dates from 25 years ago.5 It is an accessory bone located along the lateral aspect of the talus that may become severely symptomatic. We describe one patient with severely symptomatic os talus secundarius associated with subtalar coalition and calcaneocuboid subluxation, studied with plain radiographs, CT, and MRI. To the best of our knowledge, CT and MRI findings in this condition have not been described.
