The surgical treatment of cervical myelopathy due to spondylosis and disc degeneration.

A personal prospective study of the surgical treatment of cervical myelopathy due to spondylosis and disc protrusion is presented. One hundred and thirty-seven patients with severe disability have undergone surgery according to a protocol involving both the anterior approach of Cloward and decompressive laminectomy. Fifty-two percent of patients have returned to full employment, 39% to light employment and 9% remained disabled though improved from their pre-operative status. The pathenogenesis, natural history and treatment are discussed and reasons advanced to suggest that the disability resulting from severe forms of the condition may be alleviated in the majority of cases.
