Background:   Multiple axis fractures with instability are rare and appropriate treatment modalities have not been established.    Case Description:   A 33-year-old male presented with severe neck pain, bilateral upper-extremity numbness, and brisk reflexes in both lower extremities of 14 days’ duration after a car accident. The cervical CT revealed an oblique C2 body fracture and asymmetrical neural ring fractures, while the MRI showed a normal C2-3 disk. As traction failed to reduce the fracture, the patient underwent an anterior retropharyngeal approach to release the fracture fragments, followed by posteriorly passing bilateral C2 pedicle lag screws. Eight months later, the patient exhibited full range of motion across the C1-2 level with fusion of the previously noted fractures.    Conclusion:   A 33-year-old male with an unstable C2 body fracture and asymmetrical neural ring fractures successfully underwent an anterior retropharyngeal approach to release the fracture fragments, followed by posteriorly passing bilateral C2 pedicle lag screws to achieve stability/fusion.
