The Orthobullets Podcast Podiums⎪Spine⎪Fusion Rate in Standalone Versus Plated Multi-Level ACDF
6 snips
Jun 8, 2025 Dr. Francis Lovecchio, a renowned speaker on spinal surgery, discusses fusion rates in standalone versus plated multi-level ACDF. He compares biomechanical factors from various studies on cadaver spines, revealing how implant design influences outcomes. Delving into randomized trials, he emphasizes the need for standardization in evaluating surgical techniques. Lovecchio also addresses patient demographic impacts on recovery and the challenges of adopting new surgical devices, sharing insights on personal experiences with zero-profile implants.

Episode notes
Biomechanical Differences in ACDF Implants
- Biomechanical studies show plated implants provide more stiffness in flexion and extension than standalones in multi-level ACDF.
- Lateral bending and axial rotation movement remain similar between plated and standalone constructs.
Fusion Rate Comparability
- Fusion rates between standalone and plated ACDF are generally comparable in one and two-level procedures.
- Fusion assessment techniques vary greatly across studies, affecting interpretation of results.
Lordosis and Lordosis Maintenance Insight
- Four-level and higher multi-level ACDFs may lose lordosis more with standalone devices due to less flexion-extension stiffness.
- Maintaining lordosis and reducing subsidence might favor the use of plated constructs in multilevel surgeries.
