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

Abstract

In-brace correction and compliance are the main predictors of a successful outcome of brace treatment in the management of patients with idiopathic scoliosis. The latest CAD/CAM- or module-based bracing concepts related to a proper classification have led to better in-brace corrections and have made the braces easier to wear for the patient. However, even the latest developments on the market do not ensure successful treatment in every case. Thoracic curves with Cobb angles less than 50° may be treated with the best likelihood of success utilizing the latest Chêneau derivates, enabling a real 3D correction that includes sagittal correction of the spine, when patient compliance can be achieved. The successful application of the braces demands a proper classification of curve patterns. The percentage of in-brace correction of the Cobb angle correlates with the end result and consequently is a good indicator for brace quality. However, other factors, such as 3D correction or the absolute reduction of the Cobb angle (i.e., in rigid curves over 50°), might also be important indicators.
