Description

Spinal surgery has undergone significant evolution over the past several decades, transitioning from primarily open procedures to minimally invasive techniques that aim to reduce tissue trauma, postoperative pain and recovery time. These surgeries address a wide range of conditions, including degenerative disc disease, spinal stenosis, scoliosis, traumatic injuries, tumors and congenital malformations. The primary goals of spinal surgery are to relieve pain, restore spinal stability, preserve neurological function and improve overall quality of life. Advances in surgical instrumentation, imaging and intraoperative monitoring have significantly enhanced the precision, safety and effectiveness of spinal interventions.

Minimally Invasive Spinal Surgery (MISS) techniques, such as microdiscectomy, percutaneous pedicle screw fixation and endoscopic decompression, have become increasingly popular. These approaches utilize smaller incisions, specialized retractors and tubular systems, which minimize damage to surrounding muscles and soft tissues. This reduces postoperative pain, blood loss and the risk of infection while allowing earlier mobilization and faster recovery. Advanced intraoperative imaging, including real-time fluoroscopy, navigation systems and three-dimensional CT guidance, allows surgeons to accurately place instrumentation and ensure optimal spinal alignment. Additionally, intraoperative neuromonitoring, including somatosensory and motor evoked potentials, helps prevent inadvertent nerve injury and preserves neurological function.

Open spinal surgery, while associated with longer recovery and higher complication rates, remains necessary for complex deformities, tumor resections and multi-level fusions. Surgical planning involves a multidisciplinary approach, including preoperative imaging studies such as MRI, CT and X-rays, as well as consideration of patient comorbidities, bone quality and neurological status. Anesthesia plays a critical role in spinal surgery, requiring careful management of hemodynamics, ventilation and patient positioning. Prone positioning, commonly used in posterior approaches, can impact respiratory mechanics and cardiovascular function, necessitating vigilant intraoperative monitoring. Blood conservation strategies, including controlled hypotension, cell salvage and pharmacological agents, are frequently employed to reduce transfusion requirements.

Postoperative care focuses on pain management, neurological assessment, infection prevention and early mobilization. Multimodal analgesia, incorporating opioids, non-steroidal antiinflammatory drugs and regional techniques such as epidural analgesia, helps control pain and facilitates rehabilitation. Physical therapy is initiated early to improve mobility, strengthen paraspinal muscles and reduce the risk of complications such as deep vein thrombosis. Enhanced Recovery After Surgery (ERAS) protocols have been adapted to spinal surgery, emphasizing minimally invasive techniques, optimized analgesia, early ambulation and patient education to improve outcomes and shorten hospital stays. Complications, including infection, cerebrospinal fluid leak, nerve injury and hardware failure, remain risks, but careful surgical technique, meticulous monitoring and evidence-based perioperative care have significantly reduced their incidence.

Minimally Invasive Spinal Surgery (MISS) has emerged as a paradigm shift in the management of spinal pathology. Techniques such as microdiscectomy, percutaneous pedicle screw fixation, endoscopic decompression and lateral interbody fusion utilize small incisions, tubular retractors and specialized instruments. These approaches minimize trauma to paraspinal muscles and soft tissues, reduce intraoperative blood loss, lower the risk of infection and accelerate recovery. The use of advanced intraoperative imaging, including real-time fluoroscopy, navigation systems and 3D computed tomography, enables precise placement of instrumentation and accurate alignment restoration. Additionally, intraoperative neuromonitoring such as Somatosensory Evoked Potentials (SSEP) and Motor Evoked Potentials (MEP) helps detect early nerve compromise, preserving neurological function and preventing permanent deficits.

Conclusion

Advances in spinal surgery, including minimally invasive techniques, robotic assistance and enhanced perioperative care, have significantly improved patient outcomes. Careful surgical planning, intraoperative monitoring and postoperative rehabilitation are critical to preserving neurological function, reducing complications and enhancing recovery. Ongoing technological innovation promises to further refine surgical precision and patient-centered outcomes, making spinal surgery safer and more effective.
