Answer to the Letter to the Editor of Weiss HR et al. 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] We thank the authors of the Letter to the Editor for their interest in our work. It is sometimes challenging to detail brace types when performing multicentric, multiphysician studies. In the original manuscript, we specifed that we included 12 nighttime braces and 30 TLSO, without further detail; detailing the principles of correction was not feasible because four types of braces were present (CAEN, Charleston, CTM, 3D Graf–Hecquet brace). There is no consensus on which brace design is more efective for a given spinal topology; therefore, we feel that, at this stage, imposing the same brace type to all patients would not be benefcial for all patients.
