A Study to Assess the Functional Outcome After Laminotomy and Microdiscectomy in Lower Lumbar Disc Prolapse (original) (raw)

Introduction Low back pain is a very common condition which is experienced by almost 70–80% of the population at some point in their life [1]. The major cause of low back pain in the working class population is primarily an intervertebral disc prolapse [2]. Of all the cases of a low backache only clinical significant low back pain accounts to only 4–6% [2]. Degeneration of the disc causes prolapse of the disc into the intervertebral foramina causing clinical signs and symptoms [2]. The surgical results depend on detailed history, physical and radiological examination so as to assess and confirm the real cause of back pain [2]. Surgical disc removal is a simple solution for patients with severe back pain with satisfactory results [3]. The traditional technique of extensive laminectomy and discectomy lead to extensive disruption of posterior stabilization structures and complications which followed later [3].
