Abstract

Objectives: To evaluate the technique of epidural injection and its effectiveness in pain relief and functional improvement in patients with lumbar disc herniation following computed tomography (CT)-guided epidural injection. Subjects and methods: A cross-sectional descriptive study was conducted on 40 patients with lumbar disc herniation who received treatment at Diagnostic Imaging Center – Military Hospital 103. All patients underwent CT-guided epidural injection between October 2023 and May 2025. Results: 70% of patients in the study group performed heavy labor, and the onset of symptoms occurred naturally. The location and nature of the pain were diverse, with the most common being pain radiating to both legs, accounting for 35%. Before the intervention, 72.5% of patients presented with moderate pain. All patients in the study group experienced severe or very severe limitations in daily mobility. One month after the injection, pain levels decreased compared to pre-injection levels, with the majority of patients (77.5%) reporting mild pain. Patients with moderate pain accounted for 22.5%. Most patients after the injection experienced only minimal or mild limitations in mobility, accounting for 47.5% and 30% respectively. Conclusion: Common among patients engaged in heavy labor, with symptoms typically having a spontaneous onset. The location and nature of pain varied widely among patients. Most patients experienced moderate pain prior to the intervention and assessed by the Visual Analog Scale (VAS), and suffered significant limitations in daily mobility. After the epidural injection procedure, patients reported a reduction in pain levels, with most showing a marked improvement in mobility restrictions compared to before the injection.
