Abstract

Concomitant fracture of the lateral process of the talus and the sustentaculum tali of the calcaneus is a rare injury. There are few references in the literature that comment on the precise injury mechanism and the operative method for this type of fracture. We achieved satisfactory clinical results in 2 cases of concomitant fractures of the lateral process and the sustentaculum tali resulting from traffic accidents. We used a method of open reduction and internal fixation. We report these cases with a review of the relevant foreign literature because of no previous report in Korean literature.
