[Dislocations of the calcaneum, talus and navicular bones. Report of 7 cases (author's transl)].

The authors report 7 cases of sub-taloid dislocation, to which they prefer Allieu's term of talo-navicular-calcaneal dislocation, either internal (the most frequent) or external (rare) depending on the direction of displacement of the foot. After studying their mechanism, they analyse the results, which, contrary to dislocation-fractures of the talus, are usually good, in spite of the frequency of subtalal arthritis.
