About

Alexander Tuchman is a leading figure in the field of spinal neurosurgery, with a primary research focus on the precision and safety of advanced surgical technologies. His work critically evaluates the comparative effectiveness of robotic guidance, navigation-assisted techniques, and traditional freehand methods for spinal instrumentation. Dr. Tuchman’s major contributions include landmark studies that quantify the accuracy of S2 alar-iliac screw placement, demonstrating that robotic assistance significantly reduces screw malposition rates compared to freehand techniques—a finding with direct implications for reducing revision surgeries and improving patient outcomes in complex spinopelvic fixation. His 2018 study on this topic, with 65 citations, is a foundational reference in the field. More recently, his 2024 investigation into facet joint violations during adult lumbar instrumentation has advanced the understanding of how robotic and navigation systems can minimize adjacent segment degeneration. By providing rigorous, evidence-based comparisons, Dr. Tuchman’s work is shaping the standard of care for minimally invasive and robot-assisted spine surgery, making him a key voice in the ongoing technological evolution of the operating room.
