About

Karthikeyan Ponnusamy is a pioneering researcher in the field of robotic spine surgery, with a primary focus on developing and evaluating minimally invasive robotic approaches for posterior spinal procedures. His most influential work, "Robotic Approaches to the Posterior Spine" (2009, 75 citations), represents a landmark contribution to the field. In this foundational study, Ponnusamy conducted an anatomic investigation using a porcine model to systematically assess the ergonomics, control, and technical challenges of robotic access to the posterior thoracolumbar spine. This work established critical parameters for robotic surgical technique and identified key obstacles to clinical translation. Building on this foundation, his subsequent publication "Clinical Outcomes With Robotic Surgery" (2011, 25 citations) extended the analysis to human patients, providing early evidence of the safety and efficacy of robotic assistance in spinal surgery. Ponnusamy's research has been instrumental in bridging the gap between preclinical robotic concepts and practical surgical applications, helping to define the technical requirements and potential benefits of robotic systems in spine surgery. His contributions continue to inform the design of next-generation surgical robots and guide clinical implementation protocols.
