Innovations in Spinal Neurosurgery: Challenges and Solutions

Spinal disorders represent a substantial global health burden, affecting nearly 5% of the world’s population and contributing significantly to disability and healthcare utilization. Over the past century, spinal neurosurgery has evolved markedly due to advances in neuroanesthesia, antiseptic techniques, and surgical instrumentation. More recently, the integration of minimally invasive techniques, robotic assistance, augmented and virtual reality (AR/VR), machine learning, and three-dimensional (3D) printing has transformed surgical planning, execution, and outcomes. Minimally invasive spinal procedures, including tubular microdiscectomy, endoscopic techniques, and fusion approaches, have reduced tissue trauma, postoperative pain, and recovery time. Robotic-assisted spine surgery has enhanced accuracy in instrumentation placement, reduced radiation exposure, and improved workflow efficiency, albeit with challenges related to cost and operative time. AR and VR technologies have improved intraoperative navigation, surgical precision, and training of residents, while 3D printing has enabled patient-specific preoperative planning, surgical guides, and customized implants. Despite these advancements, widespread adoption remains limited by economic constraints, steep learning curves, and infrastructure requirements. Continued technological refinement, cost reduction, and surgeon training are essential to expand accessibility and maximize the clinical impact of these innovations in spinal neurosurgery.
