Figure 3 Positioning a patient on a Cotrel frame. Top view. The patient is initially supported by two metal bars, one under the shoulders and the other under the pelvis. At the same time, a strap wrapped around the patient on the convex side of the scoliotic deformity is tensioned in order to reduce it by simultaneously applying lateral and posterior reduction forces.
