Background: Lumbar disc herniation (LDH) is a major cause of low back pain and radiculopathy, significantly affecting quality of life. Minimally invasive techniques like percutaneous endoscopic transforaminal discectomy (PETD) have gained popularity due to reduced tissue trauma and faster recovery.
Objective: To evaluate the clinical and functional outcomes of PETD in patients with symptomatic lumbar disc herniation.
Methods: A prospective interventional study was conducted on patients with LDH who failed conservative management. Clinical and functional outcomes were assessed using the Oswestry Disability Index (ODI) at baseline, 2 weeks, 6 weeks, and 3 months postoperatively. Statistical analysis was performed using SPSS software.
Results: Seven patients were included in the final analysis. The mean preoperative ODI score was 36.14 ± 6.69, which significantly improved to 21.71 ± 6.04 at 2 weeks, 22.71 ± 6.70 at 6 weeks, and 23.86 ± 8.09 at 3 months (p < 0.05). Most patients showed improvement in functional status with no major complications reported.
Conclusion: PETD is a safe and effective minimally invasive technique for managing lumbar disc herniation, offering significant functional improvement and early recovery.
