To investigate the relationship between spinal cord anatomy and the risk of curve progression in mild to moderate adolescent idiopathic scoliosis (AIS). ⋯ We found significant displacement of the medulla towards the concavity of the curve in progressive AIS. This finding supports the theory of a neuro-osseous growth mismatch as a part of the etiopathophysiology of AIS and may play a predictive role in prognosis of milder cases of AIS.

This study systematically assesses the learning curve of Unilateral Biportal Endoscopic (UBE) techniques across various spinal surgeries, focusing on its influence on operative efficiency and complication rates to guide optimized training and practice. ⋯ This systematic review confirms a learning curve in UBE surgery, with improvements in operative time and complications. Procedure-specific cutoff points provide guidance for training and future research.
