Principle of the Luque- 3 Galveston technique in severe scoliosis and spastic tetraparesis. On the con- cave side of the curve a rod is anchored in the pelvis in an orthograde position as possible. The spine is then seg- mentally pulled onto the rod, thereby correcting not only the scoliosis but also the pelvic obliquity. A second rod anchored in the pelvis on the convex side and fitted with segmental wires ensures adequate stability ⊡ Fig. In our is only instrumented in the low thoracic area, a new ky- case we use the titanium pediatric USS instrumentation, phosis will develop above the instrumentation as a result as the screws and rods are rather smaller than usual and of kyphosing forces acting at this point.
