ABSTRACT
Opinion is still divided over a standard surgical procedure to decompress lumbar canal stenosis. Both, laminectomy with or without facetectomy and foraminotomy and interlaminar fenestration have been advocated. In the present communication interlaminar decompression in lumbar canal stenosis has been discussed. Sixteen consecutive patients (7 males and 9 females) with clinical, neurological and radiological features of lumbar canal stenosis were treated by interlaminar (fenestration) decompression. The age of onset of symptoms ranged between 22-57 years. Adjoining lamina around interlaminar space of involved segment along with ligamentum flavum and part of facet joint (undercutting facetectomy), extending laterally (foraminotomy) were removed at single or multiple levels. Follow-up response (93.7%) over a period of two and half years showed the results as good in 73.3% and fair in 26.7% of cases, with uniformly uneventful post-operative period.
