A Lazary, PP Varga et al. First-In-Human Study with a Novel Synthetic Bone Graft, OssDsign Catalyst®, in Transforaminal Lumbar Interbody Fusion with Instrumented Posterolateral Fusion. Biomed J Sci & Tech Res 54(4)2024.

Study background

  • First-in-human study
  • 17 patients
  • Single level TLIF with Posterolateral Fusion

Study results

  • 93% fusion at 12 months
  • Improvements in all clinical outcomes at 12 months (VAS, ODI, SF-36, GTO)
  • No graft related adverse events
Note that the referenced publication describes an investigational clinical study performed in Europe. The use of OssDsign Catalyst described in the publication may not be cleared in all markets. Please refer to your instructions for use for a full list of indications, contraindications, warnings and precautions.
