ABSTRACT Spinal orthoses are commonly prescribed to patients with moderate adolescent idiopathic scoliosis (AIS) for prevention of further curve deterioration. In conventional manufacturing method, plaster bandages are used to obtain the patient's body contour and then the plaster cast is rectified manually. With computer-aided design and computer-aided manufacture (CAD/CAM) system, a series of automated processes from body scanning to digital rectification and milling of the positive model can be performed in a fast and accurate fashion. The purpose of this manuscript is to introduce the application of CAD/CAM system to the construction of spinal orthosis for patients with AIS. Based on evidence within the literature, CAD/CAM method can achieve similar clinical outcomes but with higher efficiency than the conventional fabrication method. Therefore, CAD/CAM method should be considered a substitute to the conventional method in fabrication of spinal orthoses for patients with AIS.
摘要 脊柱矫形器常用于治疗中度青少年特发性脊柱侧凸（AIS）患者，以防止曲线进一步恶化。在传统的制造方法中，使用石膏绷带获取患者的身体轮廓，然后手动矫正石膏模型。采用计算机辅助设计和计算机辅助制造（CAD/CAM）系统，可以快速、准确地完成从身体扫描到数字矫正和正型铣削的一系列自动化处理过程。本文旨在介绍 CAD/CAM 系统在 AIS 患者脊柱矫形器制作中的应用。基于文献中的证据，CAD/CAM 方法可以达到类似的临床效果，但效率高于传统的制造方法。因此，在为 AIS 患者制作脊柱矫形器时，CAD/CAM 方法应被视为传统方法的替代方法。
