Biomechancial Comparison of a Novel C1 Posterior Locking Plate With the Harms Technique in a C1-C2 Fixation Model

Current methods of atlantoaxial stabilization rely on screw fixation. Screw placement may be transarticular, or C1 lateral mass screws in combination with pedicle or pars screws at C2. These techniques can put the vertebral artery at risk. There is also dissection around the ganglion of the second cervical nerve root, which can lead to significant bleeding or postoperative pain.
