The Evolution of Lumbar Degenerative Spinal Surgery: From Historical Foundations to Contemporary Biomechanics and Technological Innovation

Background: Neural decompression and spinal stabilization are the two foundational pillars of modern spinal surgery, each shaped by centuries of anatomical insight, technological innovation, and biomechanical conceptualization. The contemporary practice increasingly integrates minimally invasive methods, endoscopy, navigation, robotics, and motion-preserving strategies. This narrative review follows the historical trajectory of these developments, while contextualizing them within the current biomechanical and technological paradigms.
Methods: A narrative review was conducted using historical texts, landmark surgical reports, and contemporary literature indexed in MEDLINE/PubMed. Key developments in decompression techniques, microsurgery, minimally invasive and endoscopic approaches, instrumentation, imaging, navigation, robotics, and biomechanical models were examined, with special emphasis on the significant milestones influencing surgical decision-making and technique selection in spinal surgery.
Results: The evolution of decompression began at 4th century with early anatomical descriptions and culminated in the development of microsurgical and minimally invasive approaches that prioritize precision. Concurrently, stabilization techniques progressed from early wiring to pedicle screw constructs, interbody devices, and modern navigation-assisted and percutaneous fusion strategies. Advances in imaging, intraoperative navigation, and robotics-guided strategies have significantly improved surgical accuracy, repeatability, and reduced morbidity. Contemporary biomechanical frameworks, particularly Panjabi’s neutral zone model, and the integration of passive, active, and neural control subsystems of spinal stability, provide a critical foundation for understanding degenerative instability and guiding treatment selection. Persistent challenges include recurrent disc herniations, chronic axial pain, adjacent segment disease, and achieving stability while retaining physiological motion. Emerging solutions for this include motion-preserving arthroplasty, vertebral augmentation, and dynamic stabilization systems. Conclusion: Spinal surgery continues to transition toward techniques that maximize clinically meaningful decompression while preserving segmental stability and physiological motion. Future progress depends on integrating biomechanical principles with technological innovations, such as robotics, augmented reality, artificial intelligence, advanced spinal navigation, and individualized motion-preserving surgical strategies.
