All presented without a history of trauma. <\/jats:p><jats:p> All the ankles had a similar radiological appearance. Clinically, some restriction of movement was noted in three ankles and two subtalar joints, In addition, pain was noted over the posteromedial aspect of the ankle in three patients. In each patient the bipartite fragment was excised through a posteromedial approach to the ankle. Complete resolution was achieved at six months in three patients, with the remaining two describing exercise-induced symptoms. In one of these this precluded participation in sport. <\/jats:p><jats:p> Despite numerous anatomical variations within the tarsus, a case series of a bipartite talus has not previously been reported. This anatomical variation should be recognised to avoid misinterpretation as post-traumatic or other pathological processes. In the presence of recalcitrant symptoms excision is an option, but this is not universally successful in abolishing symptoms. <\/jats:p>","DOI":"10.1302\/0301-620x.92b7.23465","type":"journal-article","created":{"date-parts":[[2010,6,30]],"date-time":"2010-06-30T23:29:28Z","timestamp":1277940568000},"page":"954-957","source":"Crossref","is-referenced-by-count":13,"title":["Treatment of posterior ankle pain by excision of a bipartite talar fragment"],"prefix":"10.1302","volume":"92-B","author":[{"given":"H.
