Surgical Strategy for Cervical Myelopathy due to Ossification of the Posterior Longitudinal Ligament

Abstract

Laminoplasty is effective and safe for most patients with occupying ratio of OPLL less than 60% and plateau-shaped ossification. However, neurologic outcome of laminoplasty for cervical OPLL was poor or fair in patients with occupying ratio greater than 60% and/or hill-shaped ossification.
