For decades, chronic lumbar spine pain—caused by everything from debilitating stenosis to herniated discs—often required traditional open surgery, necessitating large incisions, extensive muscle disruption, and painful, months-long recoveries. Driven by the critical need to preserve healthy tissue while effectively treating the source of pain, the development of Minimally Invasive Lumbar Spine Surgery (MIS-LSS) launched a revolutionary era in orthopedic care. Using specialized instruments, tubular retractors, and advanced visualization systems, MIS-LSS allows surgeons to precisely target spinal issues through tiny portals, offering patients a superior alternative that dramatically reduces operative trauma, significantly shortens hospital stays, and accelerates the return to an active, pain-free life.
