Spinal fusion is a profound medical intervention, often offering the promise of relief for individuals suffering from debilitating back or neck pain. However, for a subset of patients, the journey doesn't end there. When initial fusions fail to achieve their intended goals, experience new issues like adjacent segment disease, hardware complications, or persistent non-union, the complex challenge of Spinal Fusion Revision emerges. This secondary procedure aims to address the shortcomings of the original surgery, alleviate ongoing pain, and restore stability, often requiring a more intricate approach than the initial operation to improve long-term outcomes and quality of life.
