The rate of pseudarthrosis in the lumbosacral region is especially high in patients undergoing long spondylodesis. For this reason, several procedures were developed to further stabilize the lumbosacral segment (Galveston, Dunn McCarthy). The placement of iliac screws is technically and bio-mechanically an established procedure. The placement of iliac screws can be done both navigated and based on x-ray verification. In this study, verification of correct screw placement was done by intra operative 3d scan. The tear-drop technique showed a proper screw position in the intra operative 3d scan and therefor may be considered an alternative technique to the navigated screw placement.
