Evaluates the accuracy of sacral obliquity assessment in adolescent idiopathic scoliosis, suggesting improved surgical planning methods.
The S1 endplate was the most reliable landmark for evaluating SO, particularly in patients with AIS with TL/L major curves. Given the presence of asymmetry within the S1 vertebra, use of the S1 base angle might underestimate the true degree of SO. These findings support the standardized use of the S1 endplate to enhance accuracy of SO assessment and improve precision in surgical planning and bracing strategies.
