Assessing the Socio-Psychological Determinants of Sagittal Balance

* This study investigates 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. * Posture, or sagittal balance, is a key aspect of spinal function. Considering sagittal balance is essential because its alteration leads to a decrease in quality of life and can quickly become a source of disability. Its analysis is conducted using defined parameters on spinal radiographs and is crucial for understanding spinal pathologies. Links between low back pain and posture have already been clearly reported, as well as between low back pain and socio-psychological factors. There is also evidence in the literature suggesting a relationship between socio-psychological factors and sagittal balance but these data are rare and fragmented, even though this association could be particularly pronounced in patients with spinal pathologies requiring surgical intervention.

However, it seems worthwhile to investigate this association between posture and socio-psychological characteristics in patients without spinal pathology to understand the link with other confounding or intermediate factors.

Furthermore, this association could be responsible for some of the variability in clinical and radiological outcomes of treatments, particularly surgical ones, with the presence of poor postoperative clinical outcomes despite adequate restoration of sagittal balance.

o This analytical, non-interventional study requires only one scheduled consultation within the care pathway of patients without spinal pathology consulting in the orthopaedic surgery department of the University Hospital of Bordeaux and undergoing EOS radiography as part of their care pathway. During this consultation, radiographic data and questionnaire responses will be collected.
