Background: Lumbar spinal stenosis often associates with chronic pain described the abnormal narrowing of the lumbar spinal canal, resulting in compression of neural elements within the central spinal canal or the lateral recesses or the root canals or coordinate with each other. The purpose of this study was to describe and compare the plain X-ray and magnetic resonance imaging features of lumbar canal stenosis. Materials and methods: This was a cross-sectional study of 78 patients with an acquired lumbar spinal canal between October 2017 and May 2018. Results: The X-rays confirmed osteophytes in 92.3%, endplate sclerosis in 88.5% and disc space narrowing 62.8%. On MRI, 213 lumbar levels were lumbar spinal canal stenosis, 181 lumbar levels were evaluated for the grade of central spinal canal stenosis. Conclusions: X-ray examination has limitations in a diagnosis of lumbar spinal stenosis but also serves as a diagnostic aid. MRI is well diagnosed as spinal pathology as well as lumbar spinal stenosis. Key words: Lumbar spinal, Lumbar spinal stenosis, Magnetic resonance imaging (MRI), X-ray, Grading

Background: Lumbar spinal stenosis is the most frequent indication for spine surgery. The X-ray and MRI are the choice of investigation. Justified use of radiography can be cost effective in the management of lumbar spinal stenosis. Objective: To evaluate and compare the sensitivity and specificity of the plain X-ray and MRI in the diagnosis of the lumbar spinal stenosis. Materials and Methods: A multicenter cross sectional analytical study was carried out from January 2014 to December 2015 on 70 patients of both sexes aged more than 25 years with chronic low back pain. Plain x-ray and MRI were done in all patients. The interval between plain x-ray and MRI was less than 3 months. A descriptive analysis was performed for all data. Results: The mean age (+ SD) was 45.1 (+ 5.4) years. Forty two (60%) were male and 28 (40%) were female. In plain x-ray of the lumbosacral spine, 30 (42.9%) had diskogenic spinal canal stenosis and 22 (31.4%) had both diskogenic and non diskogenic spinal canal stenosis. In the MRI, 35 (50.0%) cases had diskogenic spinal canal stenosis and 24 (34.3%) had both diskogenic and non diskogenic spinal canal stenosis. The validity of MRI evaluation for only diskogenic spinal canal stenosis was correlated, where the calculated values of plain x-ray were: sensitivity 80.0%, specificity 60.0%, accuracy 77.5%, positive predictive value 93.3% and negative predictive value 30.0%. The validity of MRI evaluation for both diskogenic and non diskogenic spinal canal stenosis was correlated, where the calculated values of plain x-ray were: sensitivity 83.3%, specificity 66.7%, accuracy 80.0%, positive predictive value 90.9% and negative predictive value 50.0%. Conclusion: Plain x-ray is a useful and reliable diagnostic modality for the evaluation, assessment and the subsequent appropriate management of lumbar spinal stenosis.

BACKGROUND: Lumbar X-rays are usually preferred in patients with lower back pain, but lumbar spinal stenosis (LSS) cannot be directly observed on lumbar X-ray films. OBJECTIVE: The purpose of this study is to explore the correlation between the degree of single-segment central LSS and lumbar X-ray measurements. METHODS: The data of 60 male patients aged 39–78 years with single-segment central LSS were analyzed. Linear correlation analysis was used to determine the correlation between the single-segment central LSS and the various measurement parameters. Multiple linear regression analysis was used to analyze the factors affecting single-segment central LSS. RESULTS: There were significant differences in S1/S0, E, B, L1-5Cobb, and M among the three groups (p< 0.05). S1/S0 was positively correlated with E, B, L1-5Cobb, and M (p< 0.05), but was not correlated with D (p= 0.66). After multiple linear regression analysis, B, L1-5Cobb, and M were independently associated with S1/S0. CONCLUSIONS: The B, L1-5Cobb, and M parameters were independently associated with single-stage central LSS, and would likely be of particular value in evaluating the degree of single-segment central LSS; B, L1-5Cobb, and M served as independent predictors of the degree of LSS. These findings will guide clinicians’ decision-making in the future.
