Letter to the editor concerning “Head to pelvis alignment of adolescent idiopathic scoliosis patients both in and out of brace” by Vergari C, Courtois I, Ebermeyer E, Pietton R, Bouloussa H, Vialle R, Skalli W (Eur Spine J; 2019: https://doi.org/10.1007/s00586-019-05981-8)

[摘要] The authors in their article refer to ‘the brace’ as if there was only one single brace design available. The specifc brace used in the study has not been described in any detail; neither has it been documented in a picture, nor did the authors name what kind of brace was used. There are in fact many diferent brace types currently available on the market. While it is a well-known fact that Boston-style braces reduce lumbar lordosis and increase thoracic fatback, in the recent Chêneau developments (Rigo-Chêneau/Gensingen brace) lumbar lordosis and thoracic kyphosis is implemented. In view of the many diferent approaches in studies involving braces, (1) the brace should be named, (2) the brace should be shown in at least one picture with a patient in-brace, and (3) the brace should be described in detail including the principles of correction applied, if applicable.
