Abstract :

INTRODUCTION Low back pain is thought to occur in almost 80% of adults in some point of their life. Its most frequent cause is due to limitation of activity in their lifestyle. Interverteal prolapsed disc is a common cause of low back pain. This study aimed at comparison of two different modalities of discectomy namely laminectomy and the fenestration discectomy via clinical trials in patients who suffered from prolapsed lumbar disc with low back pain and/or sciatica after failure of medical treatment. MATERIALS AND METHODS This is a prospective randomized study conducted in 58 patients which were diagnosed with degenerative disc disease and required surgical intervention at the level of a single lumbar segment from L2 to S1. 29 patients amongst them underwent laminectomy discectomy procedure and the remaining 29 patients underwent fenestration discectomy procedure. RESULTS VAS(Visual Analog Scale) observed for lumbar pain post operatively was approximately 1.9+0.7 and 1.4+0.6 and Prolo scale observed for lumbar pain post operatively was approximately 7.6+0.5 and 8.9+0.7 respectively in laminectomy and fenestration groups which showed significant difference. Laminectomy also produced significant instability in spine after procedure. CONCLUSION The above results led to a conclusion that the fenestration lumbar discectomy has the advantages of lesser tissue trauma, lesser duration of surgery, lesser intraoperative blood loss, early return to work,better functional and economic outcome and it would not jeopardize the stability of the spine when compared to open laminectomy procedure.
