Abstract
A bone fixation element (10) for use in spinal fixation facilitates insertion of a longitudinal spinal rod (45) in a rod-receiving channel (26) formed in the bone fixation element. The bone fixation element engages a coated spinal rod, preferably a dynamic spinal rod made from a generally non-biocompatible material such as nickel, cobalt chromium or Nitinol. The bone fixation element preferably incorporates first (120) and second (140) rod protectors to contact the coating on the spinal rod when the rod is received in the rod receiving channel of the hone fixation element. The first and second rod protectors are preferably constructed of a material having a hardness that is less than a hardness of a material of the coated spinal rod.
