BACKGROUND Cervical spondylotic myelopathy is increasingly prevalent in the elderly and is the leading cause of spinal cord dysfunction in this population. Laminectomy with fusion and laminoplasty halt progression of myelopathy in these patients; however, both procedures have well-documented complications and associated morbidity and it is unclear which might be most advantageous. OBJECTIVE We therefore compared the pain, function and alignment of patients who underwent laminectomy with fusion to those with laminoplasty for the treatment of multilevel cervical spondylotic myelopathy. METHODS We performed a retrospective matched cohort analysis on all 121 patients from 2002 to 2007 who underwent laminectomy with fusion (82) or laminoplasty (39) for multilevel cervical spondylotic myelopathy. We determined change in preoperative and postoperative sagittal alignment using Cobb measurement, development of junctional stenosis, and subjective improvements in pain and gait. Complications were recorded for both cohorts. RESULTS The majority of patients in both cohorts reported improvements in pain and gait postoperatively. There were seven complications in the laminectomy and fusion cohort (9%) with two patients requiring formal revision surgery (2%). There were five complications in the laminoplasty cohort (13%) with two formal revision procedures (5%). CONCLUSIONS Patients in both the laminectomy with fusion and laminoplasty cohorts reported similar functional improvements after treatment for cervical spondylotic myelopathy. Prospective randomized control trials are needed to determine whether one procedure is truly superior. METHODS Level IV, therapeutic study.

UI MeSH Term Description Entries
D007796 Laminectomy A surgical procedure that entails removing all (laminectomy) or part (laminotomy) of selected vertebral lamina to relieve pressure on the SPINAL CORD and/or SPINAL NERVE ROOTS. Vertebral lamina is the thin flattened posterior wall of vertebral arch that forms the vertebral foramen through which pass the spinal cord and nerve roots. Laminotomy,Laminectomies,Laminotomies
D008141 Lordosis The anterior concavity in the curvature of the lumbar and cervical spine as viewed from the side. The term usually refers to abnormally increased curvature (hollow back, saddle back, swayback). It does not include lordosis as normal mating posture in certain animals (

D011843 Radiculopathy Disease involving a spinal nerve root (see SPINAL NERVE ROOTS) which may result from compression related to INTERVERTEBRAL DISK DISPLACEMENT; SPINAL CORD INJURIES; SPINAL DISEASES; and other conditions.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
