About

Vahagan Karapetyan is a pioneering spine surgeon and researcher whose work sits at the intersection of robotic-assisted surgery and quantitative biomechanics. His primary research areas include the accuracy of robotic systems in spinal instrumentation, the development of novel three-dimensional measurement methodologies, and the clinical validation of pedicle screw placement. Karapetyan’s major contribution is the creation of a groundbreaking 3D measurement technique that objectively quantifies screw placement accuracy, moving beyond subjective grading scales. This work, detailed in his most-cited 2023 paper, provides a rigorous, replicable framework for evaluating robotic systems in spine surgery, directly addressing the field’s need for precise, evidence-based metrics. With over 5 citations already, his research is rapidly gaining traction among clinicians and engineers seeking to improve patient outcomes. Karapetyan’s achievements include being among the first to demonstrate that “steady-hand” shared-control robots can achieve sub-millimeter accuracy in complex spinal procedures, a finding that has significant implications for reducing revision surgeries and improving safety. His work is essential reading for anyone interested in the future of computer-assisted orthopedics.
