Outcome of Discectomy by Fenestration Technique in Prolapsed Lumbar Intervertebral Disc.

ABSTRACT

Background: Prolapsed disc is the major cause of low backache with radiculopathy. Many different techniques, from extensive laminectomy to minimal invasive endoscopic surgeries have been described with aim to minimize the possibility of damage to other structures. Methods: Twenty patients with clinical symptoms and signs prolapsed disc having radiological confirmation by MRI were subjected to disc excision by fenestration technique. Results: The follow-up analysis as per Modified Mac Nab’s Criteria showed excellent results in 15 patients, good in 4 patients and fair in 1. Conclusion: Discectomy by fenestration offers sufficient and adequate exposure for lumbar disc excision. Advantages over conventional discectomy are smaller incision, lesser morbidity, shorter convalescence, early return to work and comparable overall results. It can even be performed in peripheral centers where recent microscopic and endoscopic facilities are not available.
