This prospective observational study aims to evaluate the clinical outcomes of patients with single-level lumbar disc herniation who undergo routine percutaneous laser disc decompression (PLDD). In routine clinical practice, some patients receive an additional transforaminal anterior epidural steroid injection during the same session without an extra puncture. This study will prospectively follow patients who receive PLDD alone and those who receive PLDD combined with epidural steroid injection. Pain intensity, functional status, analgesic use, need for additional interventions, and complications will be assessed over time. The results may help to clarify whether adding epidural steroid injection to PLDD improves clinical outcomes in patients with lumbar disc herniation.

This is a prospective, single-center observational study conducted at the Algology Clinic of Mersin University Faculty of Medicine. The study will include adult patients with single-level lumbar disc herniation confirmed by magnetic resonance imaging who undergo routine percutaneous laser disc decompression (PLDD) as part of standard clinical care. According to routine clinical practice and physician decision, some patients receive adjunct transforaminal anterior epidural steroid injection with dexamethasone in the same session following PLDD using the same cannula after withdrawal from the disc space and confirmation of epidural position with contrast under fluoroscopy. This combined approach does not require an additional puncture and is part of standard clinical treatment. Patients will be prospectively followed and divided into two groups based on routine clinical management: those undergoing PLDD alone and those undergoing PLDD with adjunct transforaminal epidural steroid injection. Baseline demographic data including age and sex, clinical characteristics such as symptom duration and affected disc level, and comorbidities will be recorded using standardized data collection forms. The primary outcome measure will be change in leg pain intensity assessed by the Numeric Rating Scale (NRS). Secondary outcome measures will include back pain NRS, functional status evaluated using the Oswestry Disability Index (ODI), analgesic consumption, need for additional interventions, and complication rates. Follow-up assessments will be conducted at baseline, 2 weeks, 6 weeks, 3 months, and 6 months after the procedure through outpatient visits or telephone interviews. All procedures included in this study are part of routine clinical practice, and no experimental interventions will be performed. Data will be collected and analyzed in accordance with ethical standards and patient confidentiality.
