Abstract
Compare the biomechanical stability of a novel "U" posterior cervical fixation construct to four other posterior cervical atlantoaxial fixation constructs. Eight fresh frozen human cadaver spines were tested after a simulated odontoid fracture, and following stabilization with each construct. All constructs significantly decreased flexion-extension and axial rotation compared to the destabilized spine. The U construct provided significantly more axial stability than the Brooks wire technique. The novel U construct demonstrated comparable biomechanical stability to the existing constructs in all three planes of motion with the exception of axial rotation, in which it was inferior to TAS.
