We report a very rare case of anterior dislocation of the subtalar joint. F
orceful 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 subsequ
ently 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 sho
wn at three-year follow-up.
