[Classification of acetabular fractures].

Morphologic classification of fractures, however analytical they may be, is not sufficient to give precise indications as to the most adequate management decision for the various types of fractures of the acetabulum. The authors therefore find it necessary to typify these fractures on the basis of some anatomical and radiographic elements that may cause the prognosis to vary from case to case even in the same type of fracture. Two of the most important typifying factors are: articular congruity and the damage to the weight-bearing dome. The authors point out that such factors are necessary elements in the choice of a logical management decision and consider illogical an aprioristic approach whether surgical or not.
