Fine-tuning nerve monitoring during spine surgery could reduce injury risk
NCT ID NCT06120231
First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time
Summary
This study tests whether changing the pulse-width of electrical stimulation during pedicle screw placement affects nerve response thresholds. Researchers will stimulate screws with three different pulse-widths (0.4, 0.2, and 0.05 milliseconds) and record the intensity needed to trigger a muscle response. The goal is to find the most effective settings for nerve monitoring during spinal fusion surgery. The study involves 50 adults undergoing spinal surgery with pedicle screws.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help surgeons use more precise nerve monitoring during spinal surgery, potentially reducing nerve injury risk.
- What could go wrong
- This is a small, early-phase study focused on measurement, not treatment. It may not lead to any change in surgical practice.
