PEDICLE-BASED MOTION-PRESERVING DEVICE |
摘要 |
Methods and devices for a motion-preserving spinal rod are disclosed including an elongate first rod portion extending generally along a first curved path wherein at least a portion of the first curved path substantially approximates a kinematic curve defined by flexion and extension of a superior vertebra relative to an inferior vertebra. An elongate second rod portion is coupled to the first rod portion. It extends along a second curved path wherein at least a portion of the second curved path substantially approximates a posterior lordotic curve, and wherein the first curved path is oriented relative to the second curved path to substantially form an S-shaped curve. A core extends between the first rod portion and the second rod portion and a resilient damper is disposed about the core. |
