Abstract

The design of a rod is disclosed that can serve in general structural applications or as an orthopedic spinal implant to retain formation or stimulate the reduction of deformity as occurring in scoliosis and kyphosis. Different from common solid rod implants, the here-disclosed rod is curvature-adaptable in three dimensions to the actual or desired curvature or shape of the spine and can be provided with elasticity in order to serve as support or agent for curvature correction. The curvature adaptation of the proposed rod can be done with minimal force before or after implantation by means of the simple rotation of always only one in a pair of wedge shaped washers inserted between rod segments while leaving full mechanical strength or elasticity to the rod after curvature adaptation. The rotation of the washers can be done by various means, either once before implant or subsequently in the implanted state.
