Spinal Fusion Revision (https://johnasgharmd.com/revision-surgery/) is a specialized surgical procedure specifically designed to reinforce the back's structure and stability by creating a solid connection between two or more vertebrae. It becomes necessary when a previous fusion fails to heal properly (non-union), hardware issues arise, or persistent instability causes ongoing pain. Through the implantation of bone graft material, often supplemented with instrumentation like rods and screws, the goal is to achieve a stronger, unified segment of the spine, thereby eliminating painful motion, restoring structural integrity, and providing a more dependable foundation for spinal support.
