Event Description
Abstract: to determine the safety and feasibility of s2 alar-iliac (s2ai) screw placement under robotic guidance. Similar to standard iliac fixation, s2ai screws aid in achieving fixation across the sacropelvic junction and decreasing s1 screw strain. Fortunately, the s2ai technique minimizes prominent instrumentation and the need for offset connectors to the fusion construct. Herein, we present an analysis of the largest series of robotic-guided s2ai screws in the literature without any significant author conflicts of interest with the robotics industry. Twenty-three consecutive patients who underwent spinopelvic fixation with 46 s2ai screws under robotic guidance were analyzed from 2015 to 2016. Screws were placed by two senior spine surgeons, along with various fellow or resident surgical assistants, using a proprietary robotic guidance system. Screw position and accuracy was assessed on intraoperative ct o-arm scans and analyzed using three-dimensional interactive viewing and manipulation of the images. The average caudal angle in the sagittal plane was 31. 0 10. 0. The average horizontal angle in the axial plane using the posterior superior iliac spine as a reference was 42. 8 6. 6. The average s1 screw to s2ai screw angle was 11. 3 9. 9. Two violations of the iliac cortex were noted, with an average breach distance of 7. 9 4. 8 mm. One breach was posterior (2. 2%) and one was anterior (2. 2%). The overall robotic s2ai screw accuracy rate was 95. 7%. There were no intraoperative neurologic, vascular, or visceral complications related to the placement of the s2ai screws. Spinopelvic fixation achieved using a bone-mounted miniature robotic-guided s2ai screw insertion technique is safe and reliable. Despite two breaches, no complications related to the placement of the s2ai screws occurred in this series. Reported events: two patients being operated on with the robotic guidance system experienced incidental durotomies that were recognized intraoperatively and repaired. One patient being operated on with the robotic guidance system experienced an epidural hematoma that required surgical re-exploration during the initial hospital admission. One patient being operated on with the robotic guidance system developed an early pseudarthrosis after attempted l4-s1 fusion, which required a revision procedure to l3.
