[Total hip arthroplasty for the treatment of congenital hip dislocations in adults: about 15 cases].

Total hip arthroplasty for the treatment of congenital dislocation represents a challenge for the orthopedic surgeon. It is now well established that the treatment of congenital hip dislocation in adults is a real "functional miracle". The evolution of surgical techniques and materials has expanded the indications for prosthetic replacement including the most complex cases and thus going against Charnley and Feagin who wrote in 1973 that there was no place for total hip arthroplasty in inveterate dislocations.
