Abstract

There may be complications after comminuted or intraarticular calcaneal fracture regardless of the initial treatment. Transcalcaneal talonavicular dislocation is rarely reported severe form of calcaneal fracture. We experienced a neglected transcalcaneal talonavicular subluxation case, who had been treated for intraarticular calcaneal fracture conservatively. Subtalar distraction bone block fusion was done for calcaneal malunion with talonavicular subluxation. Inspite of successful subtalar fusion, pain was persisted because of talonavicular re-subluxation with arthritis and calcaneocuboid arthritis. So, second operation, the talonavicular and calcaneocuboid fusion, was done. After union achieved, the patient's foot pain was improved. Calcaneal malunion combined with talonavicular subluxation and unstable transverse tarsal joint, such as this case, initial triple arthrodesis could be considered.
