Comparative Study between Cervical Laminectomy and Cervical Laminectomy With Fixation on Clinical Outcome and Spine Stability in Patients with Degenerative Cervical Myelopathy

Abstract

Cervical spondylosis is a progressive degenerative disease of the spine and a common spinal disorder all over the world. It is characterized by multi-segmental spinal cord compression, ossification of the posterior longitudinal ligament, and cervical stenotic myelopathy. The main goals of surgical treatment in DCM are to decompress the spinal cord, maintain or restore cervical alignment and stabilize the involved segments when needed. To achieve these goals, many different surgical techniques were proposed. The choice of each one is based on patient characteristics (age, clinical symptoms, number of involved levels, site of compression, cervical alignment, previous surgeries, patients functional status, bone quality, presence of instability, among others), surgeon’s preference and analysis of risk and benefits of each approach over the other considering the case.
