Despite being the leading cause of spinal cord dysfunction among adults worldwide, little is known about the natural history of degenerative cervical myelopathy (DCM). There is mounting evidence of the effectiveness of surgery for DCM in halting progression of symptoms, and in fact, in improving neurologic outcomes, functional status, and quality of life. However, surgical decision making relies on a weighing of the risks and benefits of alternative strategies. We reviewed the available literature pertaining to the natural course of DCM and the predictors of outcome of nonoperative approaches.

ReviewEpidemiology and Overview of the Clinical Spectrum of Degenerative Cervical Myelopathy.
Degenerative cervical spondylosis (DCM) is an umbrella term used to describe myelopathy caused by various degenerative changes in the cervical spine. This article outlines the spectrum of DCM and reviews the epidemiology of each factor composing DCM. The uniform term of DCM is expected to elucidate the epidemiology of myelopathy caused by degenerative changes of the cervical spine."

ReviewOssification of the Ligaments in the Cervical Spine, Including Ossification of the Anterior Longitudinal Ligament, Ossification of the Posterior Longitudinal Ligament, and Ossification of the Ligamentum Flavum.
Ossification of the posterior longitudinal ligament (OPLL), ossification of the anterior longitudinal ligament (OALL), and ossification of the ligamentum flavum (OLF) sometimes are seen in the same patients, but the exact coexisting frequencies are not clear especially in the cervical region. The most frequent combination is OPLL and OALL. ⋯ All of these ossifying diseases of the cervical spinal ligaments are influenced by dynamic factors of the spinal column. The most frequent levels in the cervical spine affected by OPLL, OALL, and OLF are different because of anatomic differences inherent to each ligament.

ReviewIntraoperative Neurophysiologic Monitoring for Degenerative Cervical Myelopathy.
Multimodal intraoperative neurophysiologic monitoring is a reliable tool for detecting intraoperative spine injury and is recommended during surgery for degenerative cervical myopathy (DCM). Somatosensory evoked potential (SEP) can be used to monitor spine and peripheral nerve injury during positioning in surgery for DCM. Compensation technique for transcranial evoked muscle action potentials (tcMEPs) should be adopted in intraoperative monitoring during surgery for DCM. Free-running electromyography is a useful real-time monitoring add-on modality in addition to SEP and tcMEP.
