Scoliosis—an abnormal lateral curvature of the spine—has traditionally been managed with observation, bracing, or open posterior spinal fusion when the deformity progresses beyond clinically acceptable limits. While open fusion yields reliable correction, it also entails extensive soft‑tissue dissection, prolonged operative times, significant blood loss, and an extended postoperative recovery period. In recent years, minimally invasive spine surgery (MISS) has emerged as a viable alternative for select patients, leveraging tubular retractors, endoscopic visualization, and percutaneous instrumentation to achieve deformity correction through markedly smaller incisions.

The core advantage of MISS lies in its ability to preserve paraspinal musculature and reduce iatrogenic tissue trauma. By limiting dissection, surgeons can achieve comparable sagittal and coronal realignment while decreasing intra‑operative blood loss by up to 40 % and shortening hospital stays to an average of 2–3 days, versus 5–7 days for conventional fusion. Moreover, reduced postoperative pain translates into earlier mobilization and a lower incidence of chronic back‑muscle weakness—factors that are particularly relevant for adolescent and young adult cohorts who are still in developmental or vocationally active stages of life.

Nevertheless, the minimally invasive approach is not universally applicable. Severe, rigid curves (>70°) or those requiring extensive three‑column osteotomies often exceed the technical envelope of current MISS platforms, necessitating conversion to open techniques. Accurate pedicle screw placement through percutaneous trajectories also demands sophisticated intra‑operative imaging and navigation, which can increase radiation exposure if not meticulously managed. Consequently, patient selection—based on curve magnitude, flexibility, and overall health status—is paramount to optimizing outcomes.

Early and mid‑term studies indicate that, when appropriately indicated, minimally invasive deformity correction yields radiographic results that are within 5–7° of those achieved by open fusion, with comparable rates of fusion success and low complication profiles. Ongoing advances in robotic assistance, augmented‑reality navigation, and expandable percutaneous implants promise to expand the indications for Minimally Invasive Spine Surgery for Scoliosis, potentially redefining the standard of care for idiopathic and neuromuscular scoliosis in the coming decade.
