The research focuses on describing the association between socio-psychological factors, collected through standardized self-questionnaires, and the postural alignment of patients without spinal pathology consulting in the orthopaedic surgery department, as evaluated on EOS® radiographic images. This mono-centric, analytical, non-interventional, cross-sectional epidemiological study has for primary outcome to explore the relationship between socio-psychological factors and posture in patients with a healthy spine.

Correlation between Global Tilt and socio-psychological variables
The relationship between sagittal balance, assessed using EOS® imaging and measured by the angle known as Global Tilt (GT), and socio-psychological variables . Sagittal balance is normal if the Global Tilt angle is less than 23.2 degrees. When the Global Tilt angle is more than 33.7 degrees, it is considered that there is a moderate pathological imbalance of the sagittal balance
