Abstract

Correction of scoliosis imposes a displacement of the vertebrae in 3D. Until now, the movement of the vertebrae is not known. This paper proposes a protocol to measure the displacement of the vertebrae during a surgical correction procedure. The protocol permits the determination of the movement of several vertebrae in 3D using three diodes. The displacements are recorded by a videosystem and they are included by fixing a hook attached to a screw to the vertebra.
