Total Bilateral Tarsal Coalition: A Case Report.

A 35-year-old male presented with pain and swelling of his right foot and ankle. His pain developed gradually and without overt pedal deformity. The radiologic examination revealed complete fusion of all tarsal bones of his right foot. Comparative radiographs of his left foot also showed complete tarsal coalition. Ankle osteoarthritis was diagnosed, and supportive treatment enabled the patient to return to an asymptomatic status and continue the duties of his employment. This case is presented to describe an adult patient with bilateral, massive tarsal coalition who was essentially asymptomatic until degenerative arthritic changes developed in one of his ankles.
