Setting the standard of care for lumbar spinal stenosis

The Vertiflex Procedure is redefining the treatment of LSS for patients. This Level 1 evidence-based procedure is supported by data from patients who reported successful outcomes up to five years.

How it works

The Vertiflex Procedure treats the root cause of pain by lifting pressure from the nerve roots at the affected segment.

Why choose the Vertiflex Procedure

For patients with moderate LSS, the Vertiflex Procedure is designed to provide clinically proven, long-term relief.

Key features:

  • Allows for indirect decompression of the nerves while preserving the sagittal balance of the spine
  • Backed by 5-year Level 1 Randomized Control Trial (RCT) and real-world data1-5
  • Only standalone interspinous spacer FDA approved to treat moderate LSS
  • Clinically proven to treat all forms of moderate LSS: central, lateral and foraminal
  • As a reversible procedure, all future surgical options remain open

Featured clinical publications

The Vertiflex Procedure is backed by 5-year Level 1 evidence to treat all forms of moderate LSS without fusion while maintaining sagittal alignment of the spine.3,4,5 Extensive clinical data demonstrates the Vertiflex Procedure delivers 66% back pain improvement, 75% leg pain improvement, 85% opioid reduction, and 90% patient satisfaction.3,4

The prospective Vertiflex Procedure Registry confirmed high patient satisfaction from the Randomized Controlled Trial (RCT), including 80% patient satisfaction at 12 months.

Vertiflex Procedure Clinical Data

Robust clinical evidence shows that the Vertiflex Procedure is an excellent choice for patients with moderate LSS.
