A new spinal disc device showed better pain relief and function than fusion surgery in a U.S. trial, with no safety issues through 48 months.
At the DOCS Health Spine Arthroplasty Summit on November 7, 2025, Dr. Todd H. Lanman shared initial results from the U.S. Synergy Disc® 1-Level IDE trial, showing at 24 months that the device led to significantly better outcomes in neck and arm pain, and disability scores compared to traditional fusion surgery.
The trial, involving 175 patients across 20 centers, found the Synergy Disc® maintained range of motion and spinal alignment with no safety issues through 48 months.
The device, designed for patients with prior fusions, uses MRI-compatible materials and may support FDA pre-market approval by early 2026.
