Abstract

  Background: Lumbar spondylosis is a chronic disease that causes pain, limitation of movement or deformity of the lumbar spine. Nerve compression is a consequence of spinal degeneration associated with disc herniation or spinal stenosis. Magnetic resonance imaging (MRI) is a valuable tool in diagnosing nerve compression, from which appropriate treatment for the patient. Objectives: Description of clinical features, magnetic resonance imaging and the correlation in lumbar spondylosis with nerve compression at Can Tho University of Medicine and Pharmacy Hospital in 2020-2021. Materials and methods: A cross-sectional descriptive study on 102 patients with a confirmed diagnosis on MRI as lumbar spondylosis with nerve compression. Results:  The most common clinical symptom and also the reason for the patient's hospitalization is back pain, accounting for 95%; muscle atrophy accounted for 5.9%; Lasègue sign was positive with the rate of 53.9%. Magnetic resonance imaging recorded lumbar spondylosis according to Modic classification: Modic 1 (20.6%), Modic 2 (70.6%) Modic 3 (8.8%); herniated disc is the main cause of nerve compression, accounting for 81.4%; L5 nerve root was most compressed, accounting for 90%. The correlation between the clinical degree of nerve root compression and MRI: Spearman correlation coefficient r=0.57 (p<0.001). Conclusion: There is a strong correlation between the clinical degree of nerve root compression and MRI.
