On the other hand, when we used more than two iliac screws on each side, the results did not improve. On the contrary, there were a greater number of implant failures, perhaps due to the greater rigidity of the distal assembly, producing a higher number of proximal rod breakages.
Por otra parte cuando utilizamos mas de dos tornillos iliacos en cada lado los resultados no mejoraron, bien al contrario se presentaron mayor numero de fallos de implantes, quizás atribuible a la mayor rigidez del montaje distal que produce mayor numero de roturas proximales de barras.
