Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to describe normal spinal musculoskeletal patterns in healthy adolescents and young adults by using static and dynamic measures. Static informations are obtained from full-spine stereoradiography for skeletal measures and from high-resolution spine muscle MRI for muscular data. Dynamics stability is calculated from 3D gait analysis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Spinal diseases and deformities in adults (degenerative or traumatic) and children (scoliosis and kyphosis) are major public health issues.

Postural imbalance due to spinal deformity is usually measured on static radiographs, using standard X-rays. However, bipedal walk is characteristic from human being and the trunk is the main stabilizer.

Pathogenesis of spinal deformities remains undefined. To understand the different mechanisms involved in the pathological field, normal musculoskeletal performances of the spine, in static and dynamic conditions must be identified.

Ultra-low doses stereoradiography using the EOS system allows the acquisition of full-spine images in standing position. Furthermore, 3D reconstruction can also be create from both anteroom-posterior and lateral side view. Stereoradiography is used in clinical routine especially in children spinal deformities.

High resolution muscular MRI is the only device that can provide a detailed muscular analysis, with detection of abnormalities at an early stage. No mapping of normal paraspinal muscles has been yet realized, particularly regarding to rotatores muscles.

Motion analysis is the reference exam to analyse dynamic stability during gait. Several parameters reflecting stability during gait can be collected in different conditions. Recently, the "Dynamic Stability Margin" has been developed but no standard values especially in healthy children has been published.
