cuboid-navicular tarsal coalition in an athlete Sinóstosis cubo-escafoidea tarsiana en un atleta

Tarsal coalitions appear in 2% of the population, although for some the incidence of tarsal coalitions ranges from 0.03% to 0.38%1. Talonavicular and talocalcaneal coalitions are the most common symptomatic coalitions. Their presence in other tarsal joints such as talonavicular, calcaneus cuboid and naviculocuneiform joints is very rare. Leonard2, in a long series of tarsal coalitions, found that 33% of relatives and 46% of the children of patients with tarsal coalitions also had some type of coalition, with 39% of close relatives having tarsal coalitions. A total of 14% of the relatives had a different kind of tarsal coalition. The male to female ratio ranged from 4:1 to 12:51. Over 50% of the patients with tarsal coalition in one foot are likely to have the same condition in the other foot1.
