The authors should be congratulated for addressing an important and timely question in adolescent idiopathic scoliosis (AIS): can posterior minimally invasive scoliosis surgery (MISS) be safely extended to selected very severe curves exceeding 80°? Their series is technically impressive and demonstrates that, in flexible curves, curve magnitude alone may not necessarily preclude a posterior MISS strategy []. This work also adds to the growing literature suggesting that posterior MISS may achieve radiographic results comparable to conventional open scoliosis surgery (COSS) in selected AIS patients [-]. However, the key message of this study should be interpreted with caution. Demonstrating feasibility is not equivalent to demonstrating superiority, nor even equivalence, when compared with contemporary conventional posterior spinal fusion. Open AIS surgery is now highly standardized, efficient, reproducible, and reliable in experienced hands. Therefore, any expansion of MISS indications into very severe AIS must be justified by objective, patient-relevant benefits beyond scar length and radiographic correction.
