Tarsal coalitions

Tarsal coalition is a relatively rare anomaly with varying degrees of fusion between two or more tarsal bones. Symptoms, if present, usually begin early in life and include: flatfoot, decreased motion, vague foot pain, and peroneal spasm. Some persons with the anomaly never develop symptoms, so treatment should not be started until symptoms are present. If treatment becomes necessary, conservative treatment should be attempted first. If that fails, surgical intervention may be necessary.
