Posterior Cervical Laminaplasty for Myeloradiculopathy: North American Experience

  • Tapan K. Daftari

Cervical myeloradiculopathy is a syndrome that presents with a diverse constellation of symptoms and clinical findings. The common pathophysiology of this disorder is dysfunction of the nerve roots and the spinal cord as the result of compression. The most common etiology of compression is degenerative cervical spondylosis caused by osteophytic spurring, protrusion of the intervertebral disks, or infolding of the ligamentum flavum [1]. A predisposing factor is congenital cervical canal stenosis [2]. In the Japanese and non-Japanese Asian population, ossification (opacification) of the posterior longitudinal ligament (OPLL) is a predominant factor in multilevel cervical spinal cord compression [3]. The reported incidence of OPLL has increased in non-Asians in the Western hemisphere, which is likely related to heightened awareness and improved diagnostic imaging.
