U.S. Intraoperative Neuromonitoring Market Size & Share Analysis - Emerging Trends, Growth Opportunities, Competitive Landscape, and Forecasts (2025 - 2032)

The U.S. intraoperative neuromonitoring (IONM) market is projected to grow from USD 1.03 billion in 2024 to USD 1.64 billion by 2032, at a compound annual growth rate (CAGR) of 6.2%. The market growth is driven by the rising need for patient safety during complex surgeries, including spine, brain, and vascular operations. IONM plays a crucial role in minimizing nerve damage risks by providing real-time neural pathway data to surgeons. The shift toward minimally invasive surgeries, which require continuous monitoring to compensate for reduced visibility, is further accelerating the market's expansion. Additionally, the increasing preference for outsourcing IONM services is making these systems more accessible to smaller surgical centers and hospitals.

Key Insights

The systems segment accounted for the largest market share of 65% in 2024, as hospitals and surgery centers continue to invest in advanced IONM systems to ensure patient safety during high-risk surgeries.

The services category is expected to grow at the highest CAGR of 6.7%, driven by the increasing trend of outsourcing IONM to reduce equipment costs and staffing requirements while still ensuring expert monitoring.

Motor evoked potentials (MEPs) dominate the modality segment with 45% market share, widely used in surgeries involving the spine, brain, and orthopedic procedures due to their critical role in monitoring motor pathways.

Brainstem auditory evoked potentials (BAEPs) are the fastest-growing modality, with a 6.9% CAGR, driven by their increasing application in minimally invasive surgeries and their importance in auditory pathway monitoring.

Hospitals represent the largest end-user segment, primarily due to the high volume of complex, high-risk surgeries performed in these settings, where IONM is essential for patient safety.

The growing adoption of minimally invasive surgeries, such as laparoscopic and robotic-assisted procedures, is a key driver of market growth, as these surgeries require continuous neural monitoring to avoid nerve damage.

Outsourcing IONM services allows hospitals and surgical centers to manage costs more effectively while still accessing specialized expertise for complex procedures, further expanding market reach to smaller healthcare providers.
