Market Drivers

• Rising volume of complex neurosurgical procedures: The increasing volume of complex neurosurgical and spinal procedures across North America is driving the adoption of intraoperative neuromonitoring (IONM) to enable real-time assessment of neural function and reduce the risk of neurological complications. Growing emphasis on surgical precision and improved patient outcomes is further strengthening the demand for advanced IONM technologies. For instance, in May 2025, MindTrace Technologies received a USD 1.2 million Phase II Small Business Innovation Research (SBIR) award from the U.S. National Science Foundation to advance its AI-powered neurosurgical decision-support platform, supporting safer brain tumor resections and enhanced intraoperative neurological preservation.
• Increasing adoption of real-time neural monitoring: The increasing adoption of real-time neural monitoring during complex neurosurgical, spinal, and head and neck procedures is driving the growth of the North America intraoperative neuromonitoring market. Continuous assessment of neural pathway integrity enables surgeons to detect potential neurological injury immediately, improving surgical precision and patient safety. For instance, in June 2025, the U.S. Food and Drug Administration (FDA) granted 510(k) clearance to the Neuralytix iD3 System (NTX-9001), a mechanomyography (MMG)-based nerve monitoring system designed to provide real-time motor nerve mapping and monitoring during surgical procedures, supporting the broader adoption of advanced intraoperative neural monitoring technologies.

Emerging Trends

• Increasing Adoption of Multimodal Intraoperative Neuromonitoring: Healthcare providers across North America are increasingly adopting multimodal intraoperative neuromonitoring, combining somatosensory evoked potentials (SSEPs), motor evoked potentials (MEPs), electromyography (EMG), and electroencephalography (EEG) into a single procedure. This integrated approach enhances real-time neurological assessment, improves surgical precision, and reduces the risk of intraoperative nerve injury during complex surgeries.
• Growing Integration of Intraoperative Neuromonitoring with Robotic-Assisted Surgery: The growing adoption of robotic-assisted neurosurgical and spinal procedures is driving the integration of advanced IONM systems with robotic surgical platforms. This trend enables continuous neural function assessment during highly precise minimally invasive procedures, improving patient safety and supporting the expansion of technology-enabled surgical workflows.
