Fig. 10From: The new Lyon ARTbrace versus the historical Lyon brace: a prospective case series of 148 consecutive scoliosis with short time results after 1 year compared with a historical retrospective case series of 100 consecutive scoliosis; SOSORT award 2015 winnerImprovement of segmental rotation and global detorsion. The sum of initial segmental rotations is 92° i.e. an average overall torsion of 5.4°. In-brace, the arithmetic sum (negative sign if the rotation is inverted) is 15° i.e. an overall torsion of less than 1°. The overall untwisting in this case exceeds 80 %. Qualitative vectorial representation confirms the translation of the vertebral bodies along the midline with overcorrectionBack to article page
