The mechanical effect of commercially pure titanium and polyetheretherketone rods on spinal implants at the operative and adjacent levels
Publication: Spine Date: October 2010 Authors: Turner J, Paller D, Murrell C Link to Full Text Abstract STUDY DESIGN: Single-level cadaveric lumbar constructs were instrumented with either polyetheretherketone (PEEK) or commercially pure (CP) titanium (Ti) rods and biomechanically evaluated. Strain from gauged bone screws and interbody (IB) spacers, kinematic motion, and caudal disc pressure measurements were [...]
