Abstract

Objective: Review of X- ray and magnetic resonance imaging characteristics of lumbar herniated disc patients with minimal invasive surgery through dilator tube at 108 Military Central hospital. Subjects and methods: Retrospective description from january 2019 to july 2022, 81 cases of lumbar herniated disc treate with minimal invasive surgery through dilator tube at 108 Military Central hospital. Evaluating X- ray and magnetic resonance imaging characteristics. Results: There were 62/81 patients with narrowed disc space (76.5%), 49/81 patients with loss of physiological curve (60.5%) and 44/81 patients with scoliosis (54.3%). The most common herniation locations were L4-L5 (58%), L5-S1 (30.9%). The majority were lateral herniation (90.1%) and grade III degeneration (54.3%). The rate of ligamentum flavum hypertrophy was 19.8%, occurring in the group over 40 years old. Conclusion: Lumbar herniated disc was most common at L4-L5 and L5-S1, mainly grade III degeneration. Most patients have disc space narrowing and loss of physiological spinal curve, and can have ligamentum flavum hypertrophy.
