Minimally Invasive Spine Surgery – Part 3: Training, Mentorship, and the Path to Proficiency

Examining how structured training and mentorship programs can close the skills gap and ensure consistent, safe adoption of MISS techniques.

Catch up on earlier insights: In Part 1, we examined the balance between innovation and evidence in MISS. Part 2 explored the promise and challenges of endoscopic fusion. Together, they set the stage for this discussion on training and mentorship in advancing safe, consistent surgical practice.


Technology may drive the future of spine surgery, but training determines who reaches it successfully. As minimally invasive spine surgery (MISS) spreads across diverse practice settings, uneven preparation is becoming its most persistent limitation. Despite growing enthusiasm, many surgeons still face steep barriers to mastering these techniques safely and confidently.

Enthusiasm meets uneven preparation

A national survey published in the International Journal of Spine Surgery found that enthusiasm for endoscopic and minimally invasive procedures remains strong, yet surgeons identified four primary obstacles to broader adoption: the lack of structured mentorship, limited access to necessary equipment, inconsistent institutional support, and high training costs. The findings reflect a recurring theme across surgical innovation — technology often advances faster than education can keep up.

Without coordinated programs, many surgeons are left to learn through observation or short workshops, which rarely provide the hands-on repetition required for competence. As a result, even motivated clinicians can struggle to translate theoretical understanding into confident performance in the operating room.

The experience curve and its consequences

Learning MISS requires more than technical proficiency; it demands clinical judgment and patient selection skills that develop only through guided experience. A 2025 analysis involving nearly 800 surgeons participating in endoscopic training webinars found that outcomes improve steadily with experience, but complication rates rise sharply during early adoption.

Without structured proctorship or standardized curricula, early setbacks can discourage continued engagement, limiting the surgeon pool capable of performing these procedures consistently. The absence of validated mentorship models also contributes to variability in outcomes between high-volume centers and smaller institutions.

Building better training pathways

Some organizations and academic centers are beginning to address this gap. Dedicated MISS fellowships and cadaveric courses, such as the SMISS Traveling Fellowship Program and the Minimally Invasive Spine Surgery Course put on by AONA, are helping to shorten the learning curve. Virtual training and peer mentorship platforms provide valuable supplemental education, though they cannot fully replace supervised, in-person guidance.

The next step in advancing MISS depends on creating training programs that combine multiple elements, such as simulation-based rehearsal, structured feedback, longitudinal mentorship, and post-training case evaluation. Such programs could convert individual skill into reliable, reproducible standards of care.

A future built on education and accountability

MISS will continue to evolve. Yet long-term success depends on consistent education and transparent reporting, while sustained progress will require a shared commitment to mentorship. By investing in surgeon development as deliberately as in technology, the specialty can ensure that minimally invasive approaches are not only innovative but also equitable and effective across every clinical setting.
