Concomitant Occurrence of the Ossified Posterior Longitudinal Ligament with a Posterior C2 Defect

Abstract

Cervical myelopathy secondary to congenital anomalies involving the posterior elements of the axis (C2) is extremely rare.[1] We present a case of deeply invaginated unfused C2 laminae into the spinal canal with associated ossified posterior longitudinal ligament (OPLL) at the C2-C3 level presenting with myelopathy symptoms.
