As with all coalitions the main indication for operation in a Talo-Calcaneal coalition is for pain relief. Improved joint mobility may result though this is far less predictable , especially in the adult patient, and is not an indication for operation.
The classical features of a unilateral plano-valgus foot and a fixed subtalar joint are by no means invariably present. Some patients may demonstrate apparent subtalar mobility on examination due to compensatory ankle mobility.
The question in adults with Tarsal coalitions is always whether to perform a simple take-down rather than to proceed directly to fusion surgery and this is a decision made with the patient fully aware of the implications of both surgical paths.
