Abstract
Lumbopelvic fixation has increasingly become an important adjunct for stabilization of the lumbosacral spine. The ability to place larger diameter and longer screws anterior to the center of gravity of the body promotes stability both regionally and globally and can also reduce the likelihood of a pseudarthrosis or hardware construct failure [21]. For these reasons, the use of iliac screws and bolts has become popular since the original descriptions of the precursors to these methods by Allen and Ferguson [1].
