Overview

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.

* 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.

Outcomes

Primary Outcomes

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

Secondary Outcomes

Correlation between sagittal balance and BBQ questionnaire

Correlation between other parameters of sagittal balance (T1-pelvic angle, T1 slope, LL, PT, SVA) and various psychological dimensions studied per the BBQ questionnaire BBQ : Back Belief Questionnaire : Relatively easy to implement (14 questions, ranging from 0 to 5) The Back and Belief Questionnaire (BBQ) is a standardized questionnaire with 14 items that allows for a score to be established on the extent of false beliefs held by subjects.

Time frame: Baseline

Correlation between sagittal balance and SF-36

Correlation between other parameters of sagittal balance (T1-pelvic angle, T1 slope, LL, PT, SVA) and perceived health parameters (SF-36) SF-36v2® Health Survey : Benchmark score, validated by the scientific community. 36 items divided into 8 dimensions. Quick (less than 10 minutes).

Time frame: Baseline

Relation between sagittal balance and demographic variables

Relation between other parameters of sagittal balance and measured demographic variables (age, sex, weight, size, diplomas, profession, ...)

Time frame: Baseline

Correlation between sagittal balance and TSK questionnaire

Correlation between other parameters of sagittal balance (T1-pelvic angle, T1 slope, LL, PT, SVA) and various psychological dimensions studied per the TSK questionnaire TSK : Tampa Scale of Kinesiophobia : Validated for low back pain and in French. Relatively easy to implement (17 questions, the patient must respond by choosing a number between 1 (strongly disagree) and 4 (strongly agree). A score above 40 indicates a patient with significant kinesiophobia..

Time frame: Baseline

Correlation between sagittal balance and PCS questionnaire

Correlation between other parameters of sagittal balance (T1-pelvic angle, T1 slope, LL, PT, SVA) and various psychological dimensions studied per the PCS questionnaire The Catastrophism Pain Catastrophising Scale (PCS) considers both catastrophizing thoughts and behaviors, described as a catastrophizing of pain. Validated in low back pain. Easy to implement (13 questions, with scores ranging from 0 to 4). Adapted into French using the PCS-CF. A score \> 30 indicates a high level of catastrophizing.

Time frame: Baseline

Correlation between sagittal balance and HADS questionnaire

Correlation between other parameters of sagittal balance (T1-pelvic angle, T1 slope, LL, PT, SVA) and various psychological dimensions studied per the HADS questionnaire Hospital Anxiety and Depression Scale (HADS) questionnaire is Easy to implement (14 questions, divided between questions on anxiety and depression). Good internal consistency in spinal pathology Validated in French A score ≥ 11 indicates the presence of anxiety or depressive symptoms.

Time frame: Baseline

Correlation between sagittal balance and MSPQ questionnaire

Correlation between other parameters of sagittal balance (T1-pelvic angle, T1 slope, LL, PT, SVA) and various psychological dimensions studied per the MSPQ questionnaire Modified Somatic Perception Questionnaire (MSPQ) questionnaire is Easy to implement (13 questions, ranging from 0 to 3 points) Validated in spinal pathologies. The threshold has not been validated. We will use Balansyan's study as a guide, which determined that a score above 18 points appears appropriate for identifying somatic symptoms. This threshold has a sensitivity of 29% with very few false positives.

Time frame: Baseline

Correlation between sagittal balance and Big Five Inventory questionnaire

Correlation between other parameters of sagittal balance (T1-pelvic angle, T1 slope, LL, PT, SVA) and various psychological dimensions studied per the Big Five Inventory questionnaire Big Five Inventory - 10-questions short form is Easy to implement (10 questions). Short form of the Big Five Inventory validated in French. Reproducible and validated tool. Describes patients according to 5 categories: Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness. The score provides percentages for each category, indicating the patient's strengths and weaknesses.
