New device may slash radiation in spine surgery
NCT ID NCT03238521
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether an electronic conductivity device can reduce the amount of X-ray radiation needed during spine surgery. 32 adults having spine surgery were randomly assigned to receive either the standard tool or the new device. The goal was to see if the new device could lower radiation exposure for both patients and surgeons.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- electronic conductivity device (pedicle finder with impedancemetry)
- What this could lead to
- If successful, this approach could reduce radiation exposure during spine surgery, making the procedure safer for patients and surgical staff.
- What could go wrong
- This is a small, completed study with only 32 participants. The device is already used in practice, so the benefit may be modest and may not apply to all spine surgeries.
