Cervical spondylotic myelopathy. Approaches to surgical treatment.

Cervical spondylotic myelopathy is the leading cause of spinal cord dysfunction in older patients. This review article looks at the natural history of the condition and examines the role of different surgical treatments for it. Anterior and posterior surgical approaches have a role in the treatment of cervical spondylotic myelopathy dependent on the number of levels involved and the alignment of the spine. Anterior decompression and fusion is useful in patients who have disease at three or fewer levels or in patients with kyphotic alignment. In more extensive disease, a posterior decompression and fusion is usually best. Canal expansive laminoplasty is useful in the treatment of myelopathy without radiculopathy in a patient with lordotic alignment. With the exception of laminoplasty, nonfusion procedures have little role in the treatment of cervical spondylotic myelopathy.
