New tethering technique may offer Motion-Sparing alternative to spinal fusion for kids with scoliosis
NCT ID NCT03506334
First seen Jul 07, 2026 · Last updated Jul 08, 2026 · Updated 1 time
Summary
This study tests a device called the Zimmer Biomet Tether System, which is surgically placed along the spine to correct curvature in children with scoliosis. Unlike traditional spinal fusion, which permanently joins vertebrae, this tethering approach aims to guide growth while preserving flexibility. The trial compares safety and curve correction in children aged 10–16 with moderate to severe curves (40–70 degrees) who still have growth remaining.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Zimmer Biomet Tether System and Dynesys System components
- What this could lead to
- If successful, this tethering approach could offer a less rigid alternative to spinal fusion, preserving more motion in growing children with scoliosis.
- What could go wrong
- This is a small pilot study, so results may not apply broadly. Risks include curve progression, need for revision surgery, and device-related complications.
