Talus bipartitus (also known as talus partitus or frontal split) is a rare anatomic variant of the talus, first described by Strehle in 19281. Since then, to the best of our knowledge, only seven more cases have been described in the medical literature, and all of these cases occurred in adolescents who were between thirteen and eighteen years of age2-7. Three recent reports utilized a computed tomography (CT) scan for evaluation5-7, but none outlined the exact three-dimensional anatomy of the ossicle. A detailed follow-up has not been provided on any of the prior patients.
