The global intraoperative neuromonitoring market size is USD 3,658.4 million in 2024, and this number is expected to increase to USD 5,635.1 million by 2032, advancing at a CAGR of 5.7% during the forecast period (2025–2032).
This is attributed to the growing prevalence of numerous lifestyle-related chronic diseases such as cardiovascular and neurological conditions, the increasing focus on patient safety during complex and difficult surgeries, and the mounting demand for minimally invasive and advanced intraoperative neuromonitoring devices. Moreover, the high R&D spending by industry giants and various government policies support the market growth.
The geriatric population is at an increased risk of having various diseases. The increasing life expectancy and falling birth rate are the major causes of the growing aging population. As per the WHO, by 2030, 1.4 billion people around the world will be aged 60 years or more.
As age increases, the population is more likely to encounter various chronic diseases such as cardiovascular disease, neuropathic disorders, old age-related trauma, osteoarthritis, and related orthopedic disorders.
Moreover, the risk of developing spinal disorders such as lower back pain increases with age, due to the deterioration of the intervertebral discs in older people. Most of the aforementioned chronic abnormalities are treated with the help of surgical intervention. As neuromonitoring is an important part of surgeries that are associated with the nervous system, the rapidly aging population and favorable demographics across the globe would drive the demand for IONM procedures.
The systems category is the prime revenue contributor to the market in 2024, with a revenue share of around 45%, and it is also expected to grow at a significant CAGR during the forecast period. This is attributed to the surging usage of such systems in medical facilities such as hospitals and ambulatory surgery centers (ASCs) and the increasing need to monitor electrophysiological signals from a patient’s body during surgery. In addition, various instrument sets are available with the IONM system that provides monopolar stimulation and nerve monitoring during sharp dissection, which help in the minimization of nerve trauma during a surgical procedure.
The services category will witness the faster growth in the coming years, with a CAGR of around 6%. This can be due to the rising number of service providers across the globe, the increasing number of surgeries, technological advancements in medical facilities, and the growing healthcare infrastructure.
Insourced monitoring accounts for the major revenue share, and it is further expected to maintain its dominance during the forecast period. This is due to the increased surgical cases, high demand for consistent monitoring, and increased acquisitions by device manufacturers over the past few years to get a direct link with hospitals.
Furthermore, outsourced monitoring services are witnessing the higher CAGR, owing to the reducing healthcare costs, the dipping financial burden of purchasing and maintaining systems, and the rising number of outsourcing vendors across the globe.
The following offerings have been analyzed:
Hospitals dominate the market with around 65% revenue in 2024. Most high-risk surgeries are performed in hospitals by skilled professionals, who follow strict safety and efficacy protocols. Moreover, the advantages IONM offers in detecting and identifying potential damage or injury to the neural structures of the patient during a surgery are driving its usage in hospitals.
The ASCs category will witness the faster growth during the forecast period. This can be ascribed to the improved treatment provided in ASCs in numerous specialties that include neurosurgery & spine, cardiology, ENT, gastroenterology, general surgery, gynecology, and total joint replacements. Additionally, there is a surging trend of cases being transferred from primary hospitals to ASCs, mostly for reasons of patient safety, profitability, cost-cutting, and improved patient outcomes.
The report offers analysis for the below-mentioned end users:
The electromyography (EMG) category accounts for the largest revenue share, and it is expected to further grow with a substantial CAGR in the coming years. This is due to its better accuracy in identifying potential neurological damage than other monitoring modalities, the rising demand for minimally invasive surgeries, the ongoing development and mounting demand for portable EMG devices to reduce increasing hospital and healthcare-related costs, and the surging healthcare expenditures.
Brainstem auditory evoked potentials are the fastest-growing category with a CAGR of around 6.5% during 2025–2032. VEP during IONM is necessary in various types of surgeries, including transsphenoidal surgery, aneurysm clipping of the posterior circulation, and removal of tumors that lie near the optic radiation. The usage of VEPs has gained attention in recent times as a result of the advances in both monitoring and anesthetic techniques.
The scope includes these modalities:
The spine category dominates the market with around 65% revenue, and it will also witness the fastest growth. This is attributed to the advantage IONM offers in terms of enhancing the safety and precision of spinal surgeries. In spinal deformity corrections or tumor resections, where the proximity to critical neural structures requires heightened vigilance, IONM is highly advantageous. AS per the World Health Organization, 15 million people across the world are living with spinal cord injuries, which often require corrective surgery.
