Clinical Outcomes and Complications After Pedicle-anchored Dynamic or Hybrid Lumbar Spine Stabilization : A Systematic Literature Review

Abstract

Fusion is the standard in-strumentation for many pathologies of the lumbar spine. Wor-rying rates of failure, including adjacent segment degeneration (ASD), have consistently been reported. The interest for dy-namic stabilization came from the need of minimizing the long-term complications related to the restriction of the lumbar motion. However, pedicle-based dynamic stabilization advan-tages and drawbacks remain controversial.
