They are associated with high non-union rates, particularly when accompanied by ligamentous disruption and\/or fracture displacement. Posterior C1\u2013C2 fixation using the Goel\u2013Harms technique provides immediate biomechanical stability, high fusion rates, and reduces the risk of a neurovascular injury when compared with transarticular fixation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"st2\">\n                    <jats:title>Case Description:<\/jats:title>\n                    <jats:p>A 33-year-old male sustained polytrauma after a fall from &gt;3 m. The initial evaluation revealed a severe traumatic subarachnoid hemorrhage with additional complex craniovertebral junction instability. The cervical computed tomography and magnetic resonance imaging scans demonstrated an unstable Anderson\u2013 D\u2019Alonzo type II odontoid fracture accompanied by posterior displacement of the dens up to 5 mm into the spinal canal, occipitocervical dissociation, and rupture of the transverse and alar ligaments. Despite severe radiographic instability, no spinal cord injury was identified. Anterior odontoid screw fixation was contraindicated in this case due to the fracture morphology and extent of ligamentous disruption. Rather, we chose to perform the Goel\u2013Harms atlantoaxial stabilization technique utilizing C1 lateral mass and C2 transpedicular screw fixation. Adequate intraoperative reduction and restoration of alignment were achieved without neurovascular complications. Postoperatively, the patient remained neurologically intact, pain significantly improved, and stable fixation was achieved as documented on appropriate postoperative imaging.<\/jats:p>\n
