title: Total hip replacement in the paleoacetabulum: biomechanical considerations.
abstract: The authors analyze the biomechanics of the dislocated hip in preparation to total hip replacement. Using the Pauwels criteria as a starting point, the authors observe the pathologic modification of this equilibrium when the hip is congenitally dislocated. Finally, applying these criteria to the acetabular component positioned in both the neoacetabulum and the true or paleoacetabulum, the authors show that the latter is biomechanically more advantageous.
