Here is a case report of cervical ossified yellow ligament associated with cervical ossified posterior longitudinal ligament from C3 to C7 region causing myelopathy symptoms. Cervical laminectomy from C3 to C7 and excision of OYL flap from the cal sac by blunt and sharp dissection was done .patient’s neurological status improved following surgery.This article focuses the metabolic and genetic predisposition and pathogenesis of ossification of ligamentum flavum which is more common in the thoracic region and rare in cervical region.
