Objective: To evaluate the effectiveness of dynamic stabilization as an alternative to traditional fusion surgery for the treatment of lumbar disc herniation and degenerative disc disease, focusing on its impact on segmental stability and patient outcomes. Background: Back pain is a prevalent global health issue, often caused by abnormal load distribution rather than movement. Key diagnoses such as lumbar disc herniation and degenerative disc disease are linked to spinal instability. While classical surgical methods like discectomy and fusion have been standard, they often result in limited patient satisfaction and complications like adjacent segment degeneration. Lumbar Disc Herniation: Disc herniation involves the nucleus pulposus tearing the annulus fibrosus, causing pain through structural disruption or nerve root compression. Most cases resolve spontaneously, but a subset requires surgical intervention. Success of surgery depends on accurate assessment of segmental stability and patient-specific factors. Segmental Stability: Stability is crucial for preventing pain and neurological deficits. It depends on three subsystems: osteoligamentous, musculotendinous, and neural control. When one subsystem is compromised, instability occurs. Indicators for stabilization include insufficient muscle support, hypermobility, significant annular defects, and the presence of disc herniation with anterolisthesis or Modic changes. Dynamic Stabilization: Unlike rigid fusion, dynamic stabilization uses flexible materials to maintain physiological spinal movement and distribute loads. Initial systems aimed only for minor instability, but advancements now support movement preservation. Clinical outcomes show reduced adjacent segment stress and potential disc regeneration. Conclusion: Dynamic stabilization offers a promising alternative to fusion surgery by providing controlled stabilization and preserving spinal mobility. It addresses the limitations of fusion surgery, such as high complication rates and patient dissatisfaction, making it a significant advancement in the surgical treatment of lumbar disc herniation and degenerative disc disease.
