如何识别高质量的支具？
高质量的支具可以通过其产生的矫正运动来识别。在胸椎右凸弯曲中，支具应反映弯曲模式，因此至少在临床上应导致胸椎左凸外观（图 9.24）。如果支具不能使脊柱弯向对侧，则不能期望任何矫正或仅期望较低的矫正。这种矫正不足的矫正器（图 9.24 c-e）通常无法稳定角度。

图9.24。a:右侧胸弯患者。b:在GBW中，可以清楚地辨认出曲率模式的镜像。c和d:从2016年开始基于石膏铸造的过时Chêneau支具。这些在临床上显示没有矫正运动，因此效果非常有限。e:来自荷兰的M-Brace，没有对右胸弯进行任何矫正。同样，没有看到曲率模式的镜像。曲率似乎是固定的。

How do you recognize a brace of high quality?
A high-quality brace is recognized by the correction movement it produces. In a thoracic right convex curvature, the brace should mirror the curvature pattern, so it should at least clinically lead to a thoracic left convex appearance (Fig. 9.24). If braces do not lead to a mirroring of the curvature pattern, one cannot expect any or only a low correction. Such braces (Fig. 9.24 c-e) with an insufficient in brace correction will usually not be able to stabilize a curvature.

Fig. 9.24. a: Patient with a thoracic curvature to the right. b: In the GBW, a mirroring of the curvature pattern is clearly recognizable. c and d: obsolete Chêneau braces based on plaster casting from 2016. These clinically show no corrective movement and therefore are of very limited effectiveness. e: M-Brace from the Netherlands without any correction for a right thoracic curve. Again, no mirroring of the curvature pattern can be seen. The curvature seems to be fixed in its form.
