ABSTRACT

Cervical myelopathy most commonly arises due to underlying ossification of the posterior longitudinal ligament or due to cervical spondylosis, both of which are common indications for laminoplasty. The surgical procedures for revision vary according to the pathologic condition and the preferences of each operating surgeon. In the setting of a failed laminoplasty, patients should undergo preoperative computed tomography scans to determine the integrity of the hinge, as well as magnetic resonance imaging to determine if there is continued spinal cord compression. One of the surgical methods that can be used as a revision technique is revising the index procedure with a specialized laminoplasty plate. Laminoplasty is an effective treatment option for cervical myelopathy due to disc herniation. One of the commonly cited benefits of laminoplasty as compared to laminectomy is the avoidance of complications such as kyphosis or changes in spinal alignment that were associated with laminectomy.
