Purpose: To provide a detailed description of the mechanisms responsible for the corrective effect of the rigid brace Cheneau 2000.
Methods: Morphology of thoracic scoliosis is presented, including surface trunk asymmetries and radiological deformation. Biomechanical rules, applied to achieve curve correction in the three planes, are the subject of a comprehensive review.
Results: Tissue transfer in the three dimensions, elongation effect, rib cage 'derotation' and bending are the passive mechanisms of correction. Restoring of physiological thoracic kyphosis is promoted by a special combination of pads and free spaces in the brace. Hypercorrection is achievable in some clinical situations, especially for the trunk imbalance. Attention is attached to the active mechanisms of corrective bracing, comprising the modeling of vertebral growth, asymmetrically guided respiratory movements, repositioning of the spatial arrangement of trunk muscles and the anti-gravitational effect.
Conclusions: Contemporary corrective orthosis for idiopathic scoliosis should take advantage of specific passive and active mechanisms. Preservation of the function of the vertebral column as a flexible framework for the human body, as well as the preservation of the respiratory function of the thorax stay ambitious goals to approach, and a significant progress over recent years has been observed.

Feasibility of generating sagittal radiographs from coronal views using GAN-based deep learning framework in adolescent idiopathic scoliosis.

Background: Minimizing radiation exposure is crucial in monitoring adolescent idiopathic scoliosis (AIS). Generative adversarial networks (GANs) have emerged as valuable tools being able to generate high-quality synthetic images. This study explores the use of GANs to generate synthetic sagittal radiographs from coronal views in AIS patients.

Background: Multiple diseases, such as Adolescent Idiopathic Scoliosis (AIS), present at adolescent age and the impact on quality of life (QoL) prolongs into adulthood. For the EQ-5D, a commonly used instrument to measure QoL, the current guideline is ambiguous whether the youth or adult version is to be preferred at adolescent age. To assess which is most suitable, this study tested for equivalence along predefined criteria of the youth (EQ-5D-5L) and adult (EQ-5D-Y-5L) version in an adolescent population receiving bracing therapy for AIS.

Background: Lower instrumented vertebra (LIV) selection for adolescent idiopathic scoliosis (AIS) with structural lumbar curves (Lenke 3, 5, and 6) remains debated. The iliolumbar angle (ILA) measurement is useful for assessing the lumbosacral junction flexibility. If it is nonreducible, surgeons need to make a difficult choice between a potential "imperfect" L4, associated with a residual lumbosacral curve, or a more distal fusion performed later in life due to poorer functional outcomes.

Purpose: In congenital scoliosis, the surgical strategy approach of hemivertebra excision, with or without instrumentation and fusion, is a common approach to correction of scoliosis. However, hemivertebra excisions are technically challenging, with potential complications including spinal cord injury, nerve root injury and cerebrospinal fluid leak. The purpose of this study was to determine whether correction of congenital scoliosis can be achieved using a posterior instrumentation/fusion-only approach without the need for hemivertebra excision.
