Abstract

Objective: To describe the clinical and paraclinical characteristics of patients with lumbar spinal stenosis undergoing endoscopic decompression surgery. Methods: This was a prospective, longitudinal, descriptive study conducted on 50 patients with lumbar spinal stenosis who underwent endoscopic decompression surgery at Viet Duc Friendship Hospital from January 2023 to January 2025. Results: Among the 50 patients studied, the male/female ratio was 1.5/1, and the mean age was 42.8 ± 10.2 years. All patients presented with lower back pain radiating to both legs, and neurogenic claudication was present in 92% of cases. The mean VAS score for leg pain was 6.8 ± 1.9, while the mean VAS score for back pain was 6.0 ± 2.5. The mean ODI score was 59.2% ± 12.1%. On MRI, central disc herniation was the most common cause of spinal stenosis, accounting for 56% of cases. The most frequently involved disc levels were L4-L5 (52%) and L5-S1 (36%). Conclusion: The main symptoms of lumbar spinal stenosis are neurogenic claudication and pain radiating down the legs. The most commonly affected levels are L4-L5 and L5-S1.
