Expert-driven Chêneau applications: Description and in-brace corrections.

Area of Science:

• Orthopedics
• Spinal Surgery
• Biomedical Engineering

Background:

• Idiopathic scoliosis management relies heavily on brace treatment effectiveness.
• In-brace correction and patient compliance are key predictors of successful outcomes.
• Advancements in CAD/CAM and module-based bracing have improved correction and wearability.

Purpose of the Study:

• To evaluate the effectiveness of modern bracing techniques in idiopathic scoliosis management.
• To identify key factors influencing successful scoliosis brace treatment outcomes.
• To assess the role of classification systems in optimizing brace application.

Main Methods:

• Analysis of in-brace correction percentages and their correlation with treatment results.
• Evaluation of 3D correction capabilities of contemporary scoliosis braces, including sagittal plane correction.
• Assessment of patient compliance as a critical factor in treatment success.

Main Results:

• Modern bracing concepts, particularly Chêneau derivatives, demonstrate potential for significant 3D correction in thoracic curves (<50°).
• High in-brace correction percentage correlates with favorable treatment outcomes and indicates brace quality.
• Patient compliance is crucial for realizing the benefits of advanced bracing technologies.

Conclusions:

• Effective idiopathic scoliosis management requires a combination of advanced bracing, proper classification, and high patient compliance.
• While in-brace correction is a strong indicator, 3D and absolute Cobb angle reduction are also important metrics, especially for rigid curves (>50°).
• Continued innovation in bracing aims to maximize spinal correction and improve patient adherence for better long-term results.
