Vertebral rotation as a predictor of residual deformity following scoliosis correction in spinal muscular atrophy: a retrospective analysis.

ABSTRACT: This study investigated the impact of preoperative vertebral rotation (VR) on the surgical outcomes in spinal muscular atrophy (SMA) scoliosis. A retrospective analysis of 27 SMA patients (mean age 13.4 ± 4.3 years) who underwent scoliosis surgery between 2015 and 2019 was conducted. Preoperative VR was measured using Aaro-Dahlborn's and Ho's methods on computed tomography images. Surgical outcome prediction was evaluated using the Pearson correlation coefficient, linear stepwise regression, receiver operating characteristic (ROC) curve, and logistic regression analyses. Ho's method yielded significantly higher VR measurements than Aaro-Dahlborn's ( P  < 0.001). Postoperative Cobb angles correlated positively with preoperative Cobb angles ( r ² = 0.425, P  = 0.0002), Ho's method VR ( r ² =
