Serial elongation-derotation-flexion casting for children with early-onset scoliosis

Figure 4 Spinal deformity correction. While the plaster is still malleable, one-hand lateral pressure (dotted arrow) is applied on the convexity side (apical vertebra) and two-hand counter-pressure is applied on the concavity side as close as possible to the end vertebrae, and both pressures are maintained until the plaster hardens (red arrows).
