Features of Clinical and Magnetic Resonance Imaging of Lumbar Disc Herniation

Abstract

A study of 55 patients with lumbar disc herniation who were taken MRI and surgery at hospital E from January 2019 to December 2019. Results: The mean age was 58.96 ± 16.4, the female/male ratio was 1.12/1. People doing heavy work had a higher risk of disc herniation than those doing light work (63.7%). Common symptoms: lumbar pain (100%), sciatica pain, pain with mechanical properties (85.45%), limited spinal movement (90.91%), Lasègue sign (+) (74.55%), bell sign (+) (54.55%); signs of nerve root damage: sensory disturbances 72.73%, movement disorders 50.91%. Clinical lesions were common in L5 (65.45%) and S1 (45.45%) roots. Hernias were common at L4/5 (81.8%) and L5/S1 (70.9%). The degree of hernia was mainly bulge and hernia, accounting for 60% and 52.73%, respectively. 98.18% herniated to the back, central hernia accounted for the highest rate (41.82%). The rate of nerve root compression detected on MR is 90.91%. Evaluation of nerve root damage in clinical and magnetic resonance had high concordance in L5 and S1 roots (98.17% and 100%, respectively). Conclusion: MRI helps in early, accurate diagnosis and treatment orientation of lumbar disc herniation.
