Abstract
A congenital abnormality of the posterior element of the axis (C2) vertebra is extremely unusual, with just a few occurrences documented in the literature. The majority of individuals have no symptoms and are discovered by chance on plain radiography for neck discomfort, radiculopathy, or trauma. We describe a case of a 13-year-old boy who was born without the posterior element of the C2 vertebrae, resulting in C2-C3 spinal instability and compressive myelopathy.
