Four patients sustaining tarsal navicular body fractures are presented. Analysis based on these cases and on 36 patients suffering from identical fractures reported in the literature led to a new mechanical assumption: the axial compression on the foot, as a result of falling from height, causes impaction of the talus into the body of the navicular bone. The clinical followup results reported are usually disappointing. Favorable results are obtained in a vertical two-part fracture, by an open reduction and internal fixation of the tarsal navicular body fracture. In highly comminuted fractures, talo-navicular-cuneiform arthrodesis can be carried out.
