Surgical management of an isolated symptomatic talonavicular coalition: a paediatric perspective.

Talonavicular (TN) coalition is a rare pathological union of the talus and navicular bones. We report the case of a 7-year-old girl with a symptomatic TN coalition, who underwent operative management with a lateral column lengthening procedure using autologous iliac crest bone grafting. There are no complications to report and the graft was incorporated at an early stage. At 3 year follow-up the patient has remained pain-free since the operation and maintained alignment. To our knowledge, this is the first reported case of TN coalition treated with reconstructive surgery in a paediatric patient.
