The “D modifier” can be complemented by a compression-traction superstructure, when the apical region of the proximal curve is around T3–4 (a). The traction principle, applied from the left side, to pull the neck right to left, is the equivalent to the proximal point of the secondary “three-point system” working to correct the proximal curve, and it is complemented by a compressive force applied on the left trapezium prominent line, classically associated to the structural proximal curve. This proximal point of the “three-point system” can also be provided by an extra-high, but still underarm, right proximal pad, but only when the apical vertebra of the proximal curve is around T4–5 (b). Figure 13 shows the prototype of these two approaches
