title: Kinematics of the Zielke procedure (VDS) in scoliosis. Intraoperative measurements.
abstract: The Zielke correction technique (VDS) has two parts, derotation and ventral convex-side compression. Both were studied by measurements made during and after the operation. Ventral derotation always creates lordosis. Lordosis can be maintained during compression by insertion of intervertebral bone blocks, or kyphosis created by omitting them.
