Abstract: Background/Objectives: Adolescent lumbar disc herniation (ALDH) is rare. Evidence on long-term surgical outcomes remains limited. The objective of this study was to evaluate mid- and long-term clinical outcomes following lumbar microdiscectomy in adolescents with lumbar disc herniation (LDH). Methods: A single-institution retrospective cohort study of patients under 19 years who underwent lumbar microdiscectomy over a ten-year period. Baseline clinical and radiological data were obtained from electronic patient records (EPR) and Magnetic Resonance Imaging (MRI). Patient-reported outcomes were collected at follow-up using the Oswestry Disability Index (ODI) as the primary outcome and Numeric Rating Scales (NRS) for back and leg pain and Global Perceived Effect (GPE) as secondary outcomes. Descriptive statistics were used to summarize results. Results: Seventeen of 27 patients (63%) participated. Mean age at surgery was 16.9 years, and mean symptom duration prior to surgery was 11.3 months. All patients underwent disc-preserving microdiscectomy. At a mean follow-up of 67.7 months, mean ODI was 9.5, mean NRS back pain was 2.8, and mean NRS leg pain was 2.3. Fourteen patients (82%) reported being completely recovered or much improved. Conclusions: Lumbar microdiscectomy in adolescents with LDH showed acceptable mid- to long-term outcomes, low disability, and low pain levels at more than five years of follow-up. Clinical and imaging findings resembled those seen in adults, though symptom duration before surgery was prolonged.
