Luque fixation to the sacral ala using the Dunn-McCarthy modification

The Galveston-Luque technique of fixation to the pelvis requires solid bone and a strong pelvis. Because the majority of neuromuscular patients who require fixation to the pelvis have a weak and thin illum, an alternative to the Galveston technique was sought. A technique of rod contouring was developed that takes advantage of the reliable, stout bone of the sacral ala for fixation. Twenty-four patients have been instrumented with Luque rods and fused to the sacrum over the past 4 years using the technique. There have been no complications in this short follow-up.
