Clinical Trial Summary

Adolescent Idiopathic Scoliosis (AIS) is the most frequent spinal deformity in adolescence, but its etiology remains unknown. Recent publications suggest a link between ciliopathy and AIS. More specifically a modification of the cerebro-spinal fluid (CSF) flow by ciliary dysfunction could be at the origin of a scoliotic deformity. This study aims to compare the CSF flow measured by magnetic resonance imaging (MRI) in an AIS group and a control group.

Gender Female
Age group 12 Years to 17 Years
Eligibility Common Inclusion Criteria for the 2 groups : - Female subject aged 12 to < 18 years old - Affiliated to the French social security system - Having signed the inform consent form - Whose parents have given their consent Additional Inclusion Criteria for the AIS group: - Subject with right thoracic AIS defined by the existence of a 3D spine deformation with a frontal deviation to right dorsal convexity with a Cobb angle of at least 20°, and a rotation of at least 20°, as evidenced by the presence of a vertebral gibbosity = 5° at the Bunnel scoliometer. If the scoliosis has more than one curvature, the right chest curvature should be the greatest high (highest frontal Cobb angle) - Subject with x-rays of total spine, face and profile under load, according to the EOS technique, dating from less than 3 months. Common Exclusion Criteria for the 2 groups: - Instability to submit to the medical follow-up of the study for psychic, social or geographical reasons - At least 6 "cafe au lait" spots with a size = 1.5 cm (may be suggestive of neurofibromatosis) - Ligament hyperlaxity confirmed by a Beighton score >4/9 (which may be suggestive of scoliosis secondary) - Contraindications of a cerebro-medullary MRI: claustrophobia, foreign bodies, and ferrometallic clips of the trunk or cephalic segment, cochlear implants, stimulators and implantable cardiac defibrillators, insulin pump - Inequality in length of the lower limbs = 20 mm on clinical examination - Subject presenting neurological signs (signs of pyramidal irritation, sensory-motor deficit, clinical signs suggestive of cerebellar pathology ...) - Known vestibular pathology - Taking psychotropic drugs Additional exclusion criterion for the AIS group: - Subject with secondary scoliosis : neurological, orthopedic, malformative... Additional criteria for the control group: - Subject with a scoliosis angle = 10° on a photogrammetric screening assessment (optical process, non-irradiating, which allows an Morphometric evaluation of the trunk in 3D, thanks to the analysis of the trunk reliefs) - Subject whose clinical examination shows a gibbosity measurable (>5°) with the scoliometer of Bunnel

Outcome

Type Measure Description Time frame Safety issue
Primary CSF flow (cm/s) at the 7th thoracic vertebra (T7) The flow will be measured by MRI 6 months
Secondary CSF flow (cm/s) at the cervico-occipital junction The flow will be measured by MRI 6 months
Secondary CSF flow (cm/s) at the cerebral aqueduct The flow will be measured by MRI 6 months
Secondary Prevalence of spinal cord abnormalities Measured by MRI 6 months
Secondary Correlation between the Body Mass Index and the CSF flow (cm/s) at the 7th thoracic vertebra (T7) This association will be studied by a linear regression analysis 6 months
Secondary Cobb frontal angle in degrees The measurement of radiographic parameters will be done with the EOS system. The EOS system is a new slot-scanning radiological device that allows simultaneous acquisition of frontal and lateral images. It is composed of two X-ray sources, shaped as fan beams through collimation slits. 6 month
Secondary Distance between the vertical line passing through the middle of the sacrum and the vertical line passing through the spine of the 7th cervical vertebra. 6 month
Secondary Angle of thoracic kyphosis T4-T12 in degrees The measurement of radiographic parameters will be done with the EOS system. 6 months
Secondary Lumbar lordosis angle L1-L5 in degrees The measurement of radiographic parameters will be done with the EOS system. 6 months
Secondary Lumbo-sacral angle L5-S1 in degrees The measurement of radiographic parameters will be done with the EOS system The measurement of radiographic parameters will be done with the EOS system. 6 months
Secondary Pelvic incidence in degrees The measurement of radiographic parameters will be done with the EOS system 6 months
Secondary Subjective Postural Vertical Measurement in degrees 6 months
Secondary Subjective Visual Vertical Sight Measurement in degrees 6 months
Secondary Proprioception Measurement in degrees Proprioception measurement obtained by trunk repositioning error test (Formetric system) 6 months
