<p>Method for correcting the shape of a spinal column. A rod is attached to the vertebrae in the longitudinal direction of the spinal column, at the rear thereof, across the part which is to be corrected. The rod consists of a material, for instance of an Ti-Ni-alloy, with a shape-memory with a transition temperature, lower than the body-temperature. The rod is bent and possibly twisted, corresponding to the curve and/or torsion of the spinal column at a temperature, under the transition-temperature. The rod has a perpendicular cross-section with a linear size in one direction, at least so large, that above the transition-temperature, the rod wants to assume its original shape with a constant force. <IMAGE></p> |
