Abstract
Os talus secundarius is an extremely rare accessory ossicle located at the lateral aspect of the talus just anterior to the fibula. Although rarely seen, it may cause lateral-sided chronic ankle pain. Only a few cases of symptomatic os talus secundarius have been reported to date. Herein, a 42-year-old male patient with symptomatic os talus secundarius is presented, and its imaging findings, differential diagnosis, and treatment are discussed.
Level of evidence: Level IV.
