Sub - Talar Dislocation Neglected (About a Case)

The sub talar or peri - astragalian dislocation is a loss of the anatomical relations between the astragales, calcaneum and scaphoid. The congruity of the tibio - peroneo - astragales joint is maintained. It is a rare lesion that accounts for 1% of all dislocations. Internal variety is by far the most frequ ent.
