Abstract

Objective: Review of X- ray and magnetic resonance imaging characteristics of double- level lumbar spondylolisthesis patients with sugery at 175 military hospital. Subjects and Methods: Retrospective description from 5/2020 to 12/2023, 30 cases of double- level lumbar spondylolisthesis were operated by transforaminal lumbar interbody fusionat at the Department of Neurosurgery in 175 Military Hospital. Evaluating X- ray and magnetic resonance imaging characteristics. Results: On X-ray, 60% of patients had spondylolisthesis at L4L5S1 and 40% had spondylolisthesis at L3L4L5. Most patients had grade I spondylolisthesis (63.3%); only 36.7% had grade II spondylolisthesis; 50% of patients had isthmic defect and 60% of patients had degenerative changes on X-ray. On MRI, all patients had disc herniation, of which 86.7% had two-level disc herniation and 13.3% had one-level disc herniation. Most patients had spinal stenosis, foraminal stenosis, facet joint hypertrophy and ligamentum flavum hypertrophy (76.7%). Conclusion: On X-ray, the most common location of spondylolisthesis is L3L4L5 (60%); most patients have grade I spondylolisthesis (63.3%). On MRI, all patients with 2-level spondylolisthesis are often accompanied by disc herniation and the majority have spinal canal stenosis, foraminal stenosis, facet joint hypertrophy and ligamentum flavum hypertrophy (76.7%).
