Indications for Revision Spine Surgery
Revision spine surgery is necessary when primary interventions result in pseudoarthrosis, implant failure, flatback deformity, or severe adjacent segment disease (ASD), culminating in Failed Back Surgery Syndrome (FBSS).
Advanced Reconstructive Techniques
- Microscopic Scar Neurolysis: Delicate liberation of entrapped nerve roots from dense epidural fibrosis.
- Sacropelvic Anchoring (S2AI Screws): Providing maximal biomechanical purchase to achieve definitive fusion in high-stress construct areas.
