Pelvic Fixation Using S2AI and Triangular Titanium Implants (Bedrock Technique).

World Neurosurg 2021 10 15;154. Epub 2021 Jul 15.

Department of Neurosurgery, University of Minnesota, Minneapolis, Minnesota, USA; Department of Orthopedic Surgery, University of Minnesota, Minneapolis, Minnesota, USA.

Pelvic fixation is becoming an increasingly important caudal anchor point for long lumbar constructs, high-grade spondylolisthesis, fixation of sacral fractures, and support for 3-column osteotomies, by adding lumbosacral fixation anterior to the McCord pivot point. Iliac bolts were once common but have become less favorable due to screw head irritation and complications associated with connecting rods. S2-alar-iliac (S2AI) screws have been shown to achieve equivalent anchoring strength of constructs to the pelvis, while being lower profile and in line with the lumbar instrumentation. Read More
