Anterior dislocation of the subtalar joint: a case report.

We report a very rare case of anterior dislocation of the subtalar joint. Forceful supination of the foot and dorsiflexion of the ankle was considered the cause of the injury in this case. Closed reduction was successful for the talocalcaneal component of subtalar joint, although surgery was subsequently performed because of the residual subluxation of the midtarsal joint including the talonavicular component of subtalar joint and the associated fracture of the lateral process of the talus. Satisfactory results were shown at three-year follow-up.
