Abstract:
Low back pain due to lumbar disc prolapse is the major cause of morbidity throughout
the world affecting mainly young adults. Different surgical techniques for lumbar discectomy are in vogue
with the aim of least possible damage to other structures while dealing with the prolapsed disc. This short term
prospective study was done to assess the functional outcome interlaminar fenestration discectomy. Materials
and Methods: Thirty six patients with clinical symptoms and signs of single level prolapsed lumbar
intervertebral disc having radiological correlation by MRI study were subjected to disc excision by interlaminar
fenestration. Outcomes were measured using the visual analogue scale (VAS) for back and leg pain, Roland-
Morris score (RM) improvement and modified Macnab criteria at 3 months, 6 months and 2 years. All
quantitative data were summarised using mean and standard deviation, and qualitative data using proportions.
