A biomechanical analysis of Zielke, Kaneda, and Cotrel-Dubousset instrumentations in thoracolumbar scoliosis. A calf spine model.


A biomechanical study was performed in order to evaluate the initial stability of three spinal instrumentation systems, applied to a scoliosis model. Five calf spines (T11-L2) were destabilized anteriorly, and, by inserting a wedge-shaped resin disc within each destabilized intervertebral space, a thoracolumbar scoliosis was created. Three spinal… (More)
