Drivers

The increasing volume and complexity of surgical procedures is driving the market

The increasing volume and complexity of surgical procedures is a primary driver for the intraoperative neuromonitoring (IONM) market. As surgeons undertake more intricate operations, particularly in fields like neurosurgery and spine surgery, the potential for nerve damage increases significantly. Real-time monitoring of neural pathways during these complex procedures allows surgical teams to identify and mitigate potential injuries, directly enhancing patient safety and improving functional outcomes. This heightened awareness of the need to protect neurological function during surgery fuels the demand for specialized monitoring equipment and skilled personnel.

The expansion of companies providing solutions for these procedures reflects this growing need; for instance, Globus Medical, a key player in musculoskeletal and spine technologies, reported that its worldwide net sales increased by 60.6% in fiscal year 2024 compared to fiscal year 2023, indicating significant market growth in surgical areas where neuromonitoring is frequently utilized.

Restraints

Cost pressures on healthcare providers are restraining the market

Cost pressures on healthcare providers are restraining the intraoperative neuromonitoring (IONM) market. Hospitals and surgical centers face persistent financial constraints driven by factors including fluctuating reimbursement rates, rising operational expenses, and the considerable capital investment required for advanced medical technologies.

While the clinical benefits of IONM in preventing costly complications are recognized, the direct costs associated with acquiring and maintaining monitoring systems, as well as the professional fees for monitoring services, can be substantial. This financial burden can lead some healthcare facilities to carefully scrutinize the necessity and cost-effectiveness of IONM for various procedures, potentially limiting its broader adoption or driving negotiations for lower service costs.

US hospital expenditures grew by 10.4% to reach US$1.5197 trillion in 2023, illustrating the increasing financial demands on healthcare providers that can influence their technology adoption and service utilization decisions.

Opportunities

Expanding applications in new surgical areas are creating growth opportunities

Expanding applications in new surgical areas are creating significant growth opportunities for the intraoperative neuromonitoring (IONM) market. Initially focused primarily on spine and neurosurgery, the utility of IONM is increasingly being recognized and adopted in a wider range of procedures, including complex orthopedic surgeries, vascular procedures, and even some head and neck surgeries where nerves are at risk. This diversification of applications broadens the potential market for neuromonitoring services and equipment beyond traditional boundaries.

As clinical evidence mounts demonstrating the value of IONM in improving outcomes and reducing complications in these new areas, adoption is expected to rise. Companies are actively exploring and developing monitoring techniques tailored for these emerging applications, seeking to capitalize on untapped market segments and drive further growth.

Impact of Macroeconomic / Geopolitical Factors

Macroeconomic and geopolitical factors influence the intraoperative neuromonitoring (IONM) market. Economic conditions directly impact healthcare spending by institutions and individuals, affecting hospitals’ capital budgets for purchasing monitoring equipment and the ability of patients or insurers to cover the costs of procedures where monitoring is used; during periods of economic growth, hospitals may increase investments in advanced technologies like IONM, while economic contraction can lead to tighter budgets and delayed purchasing decisions.

Geopolitical stability plays a crucial role in maintaining consistent global supply chains for the specialized electronic components and materials needed to manufacture sophisticated monitoring devices. Reports in early 2025 indicated that geopolitical risks were contributing to disruptions across various global supply chains, which impacts the medical device sector.

Despite potential negative impacts from economic volatility and supply chain vulnerabilities, the increasing emphasis on enhancing patient safety and minimizing neurological complications during surgery provides a fundamental driving force for the adoption and continued development of neuromonitoring technology, encouraging market resilience and efforts to secure supply chains.

Current US tariff policies can indirectly impact the intraoperative neuromonitoring (IONM) market by influencing the cost of imported components and finished goods. Many sophisticated medical devices, including IONM systems and their parts, rely on complex global supply chains for manufacturing, and tariffs imposed on these imported items can increase the production costs for companies operating in the US market.

For instance, in 2023, the US imported instruments and appliances used in medical or surgical sciences (under HTS 9018.90) with a Customs Value of approximately US$8.68 billion, and calculated duties on these imports amounted to approximately US$27.9 million, indicating the scale of imports and the associated tariff costs in this broad category which includes neuromonitoring equipment. These increased input costs pose a financial challenge for manufacturers and could potentially lead to higher prices for IONM equipment and related services, impacting the purchasing decisions of healthcare providers.

However, the significant clinical benefits of preventing surgical complications through effective neuromonitoring create a strong incentive for hospitals to adopt this technology, prompting stakeholders to seek ways to absorb costs or optimize supply chains to ensure continued access.
