Abstract

Background: Degenerative Cervical Myelopathy (DCM) is an age-related disease of the cervical spine and represents one of the most common causes of spinal cord dysfunction. Surgical intervention is the cornerstone of management in symptomatic cases,but the approach of choice is always debatable.
Purpose: Was to compare between mutltilevel cervical laminectomy,and multilevel cervical laminectomy with lateral mass fixation in patients with cervical spondylotic myelopathy regarding the functional clinical outcome and cervical spine normal sagittal alignment.
Patients and Methods: This work is a prospective study of two groups of randomly selected patients. The first group (n= 20) underwent cervical laminectomy while the second group (n=18) underwent cervical laminectomy with lateral mass fixation. Patients were followed up for 12 months duration using functional modified Japanese orthopedic association (mJAO)score, andmeasurement of C2-C7 cobb`s angle to evaluate post-operative cervical sagittal alignment.
Results: Results revealed that both approaches have better post-operative functional outcome with no significant changes on the normal cervical lordosis. Results alsoshowed no statistically significant difference in clinical outcome between the 2 groups after one year follow up.
Conclusion: Both simple multilevel posterior cervical laminectomy and posterior cervical laminectomy with lateral mass fixation are associated with improvement in the functional outcome in CSM patients with no changes in normal cervical lordotic sagittal alignment in at least 12 months follow up duration.
