Current concept of bracing must take in consideration both the three-dimensional (3D) nature of Adolescent Idiopathic Scoliosis (AIS) and its pathomechanism of progression. A modern brace should be able to correct in 3D in order to break the so called 'vicious cycle' model. Generally speaking, it is necessary to create detorsional forces to derotate in the transversal plane, to correct the lateral deviation in the frontal plane and to normalize the sagittal profile of the spine. Breathing mechanics can be used to fight against the thoracic structural flat back. The original Chêneau brace was introduced at the end of the 70's and its principles were based more in anatomical observations rather than in biomechanics. A further evolution , enunciating new principles, has allowed a higher standard, improving in brace corrections and trunk modelling. This biomechanical principles have been developed under the name of Rigo-Chêneau-System (RSC) and used later in latest brace models like the Chêneau light with reduced material, and similar in brace corrections. Experience is also important to improve the end results. The blueprints to built the brace according to the anatomorradiological pattern are very helpful.
当前的支具概念必须兼顾青少年特发性脊柱侧凸(AIS)的三维(3D)特性及其进展的病理机制。现代支具应能够进行三维矫正,以打破所谓的“恶性循环”模式。一般来说,有必要产生去旋转力,在横向平面上进行去旋转,纠正额状面的侧方偏移,并使脊柱矢状面轮廓正常化。呼吸力学可用于对抗胸廓结构性平背。最初的施诺支具于70年代末推出,其原理更多基于解剖学观察而非生物力学。进一步的发展阐明了新的原理,实现了更高的标准,在支具矫正和躯干塑形方面有所改进。这种生物力学原理以里戈 - 施诺系统(RSC)的名义得以发展,后来应用于最新的支具模型,如材料减少的施诺轻型支具,在支具矫正方面类似。经验对于改善最终结果也很重要。根据解剖放射学模式制作支具的蓝图非常有帮助。
