Estimated Three-Dimensional Thoracic Kyphosis Supplements Radiographic Bone Age in Predicting Adolescent Idiopathic Scoliosis Curve Progression.
Estimated thoracic kyphosis alone strongly predicts adolescent scoliosis curve progression risk.
Estimated Three-Dimensional Thoracic Kyphosis Supplements Radiographic Bone Age in Predicting Adolescent Idiopathic Scoliosis Curve Progression.
Accurate prediction of curve progression in adolescent idiopathic scoliosis remains challenging.
To evaluate whether estimated 3-dimensional thoracic kyphosis (e3DTK) adds predictive value to radiographic bone age in identifying adolescent idiopathic scoliosis (adolescent idiopathic scoliosis) patients at risk for curve progression.
Were additionally stratified by Sanders score and e3DTK risk category to evaluate subgroup progression rates.
Sanders score demonstrated strong predictive performance (AUC=0.80).
However, this did not outperform Sanders-based prediction or improve combined models.
Stratified analyses showed higher progression rates in high-risk e3DTK groups across Sanders stages (P=0.022), suggesting within-stratum risk differentiation.
e3DTK is associated with adolescent idiopathic scoliosis curve progression and demonstrates discriminatory ability in univariate analysis; however, it does not improve predictive performance beyond Sanders skeletal maturity staging.
While it may help characterize risk heterogeneity within maturity strata, its role appears complementary rather than independently additive in adolescent idiopathic scoliosis progression prediction.
