Objective: Aim of this study was to assess functional and neurological outcome by fenestration technique, since standard laminectomy and discectomy carries a risk of spine instability, it is preferable to perform discectomy through fenestration. Methods: Out of the 51 patients who were operated for single level lumbar disc herniation by fenestration discectomy between 2009 to April 2011, only 48 patients were available for follow up. Patients were followed up for a period of 1 year. The post operative outcome was analysed using the JOA score. The outcome was analysed with motor deficit, sensory deficit and bladder function as variables. Results: Back pain improved immediately in almost all 48(100%) patients. The outcome was excellent in 35.4%% patients good in 56.3% and fair in 8.3%. Conclusion: Fenestration technique with minimal disc removal is an effective technique for treating properly selected patients.
