Biomechanical evaluation and comparison of polyetheretherketone rod system to  traditional titanium rod fixation on adjacent levels

Conclusion In comparison with rigid fixation, some potential advantages of using PEEK rod systems include a reduced stress on adjacent segment disc and facet joint, and the elastic ability of PEEK rod fixation allows for a greater range of motion, which may reduce the incidence of clinical complications seen with rigid fusion devices.
