title: Ossified Ligamentum Flavum causing Cervical Myelopathy.
abstract: Ossification of the ligamentum flavum (OLF) causing compressive cervical myelopathy or radiculopathy is rare. A 50-year-old male was admitted for progressive hypesthesia and paresthesia of both hands and a gradually worsening gait. MRI and CT scans demonstrated ossification of the left ligamentum flavum with dural sac and cord compression at the C5-6 level. The ossified ligamentum flavum was removed through a subtotal laminectomy and left side foraminotomy of the C5-6. Postoperatively, his gait improved remarkably and the sensory symptoms gradually resolved.
