To define the relationship between 3D radiological features, psychological factors, and back pain prevalence and intensity in patients with adolescent idiopathic scoliosis (AIS).


Consecutive AIS patients answered self-reported questionnaires and underwent simultaneous posterior–anterior and lateral scans of the spine (EOS Imaging, Paris, France). 3D reconstructions of the spine and pelvis reported 18 parameters in the coronal, sagittal, and axial plane.


Hundred and twenty-four patients with AIS were included in the study. Overall, 90% of AIS patients reported having some back pain over the last 6 months and 85.8% over the last 30 days. Pain intensity in the last month was reported to be mild in 37.5%, moderate in 31.8%, moderate to severe in 24.3%, and severe in 6.54% of cases. Location of back pain was associated with location of main curve (P = 0.036). Low back pain was associated with higher lumbar apical AVR and lower lumbar lordosis (P
