It is a congenital or acquired condition of the foot that is usually diagnosed in individuals between the ages of eight to twelve years old and may be seen in some sports medicine clinics as a cause of foot pain.

Although coalitions can occur between any tarsal bones, calcaneonavicular coalitions are the most frequent ones, accounting for 53% of tarsal coalitions.
