The value of cervical MRI in surgical lumbar canal stenosis patients

Background The prevalence of cervical canal stenosis alone is estimated to be present in 4.9% of the adult population. Co-existence of dual pathology may complicate clinical presentation and necessitates a wise and individually based decision process. Objectives To estimate the co-existence of cervical canal stenosis in surgical lumbar canal stenosis patients and its reflection on decision-making regarding surgery. Methods It is a prospective study that was conducted on 70 cases with symptomatic lumbar canal stenosis by investigating them for cervical canal stenosis clinically and radiologically. Results The co-existence of cervical and lumbar canal stenoses was seen in 62 cases (88.57%); cases with relative cervical stenosis were 25 (35.714%) and absolute cervical stenosis was 37 (52.857%). Cases with no cervical stenosis were 8 (11.428%) and cases with relative lumbar stenosis were 22 (31.428%), while cases with absolute lumbar stenosis were 48 (68.571%). Cases with symptomatic cervical canal stenosis were 30 (42.857%). Cases with asymptomtic cervical canal stenosis were 32 (45.71%). Conclusion Tandem spinal stenosis (TSS) is not uncommon and MRI cervical spine should be done for every lumbar canal stenosis patient especially if indicated by history or clinical examination.
