Introduction and Objectives: The present study was undertaken with the objective to study the functional
outcome with Oswestry Disability Index and VAS in patients with degenerative lumbar canal stenosis who
underwent unilateral laminotomy and bilateral decompression of the canal.
Materials and Methods: The cases were the patients who underwent microsurgical treatment for
degenerative lumbar canal stenosis, between the age group of 40 to 60 during 2008 – 2010 were taken
for the study. Patients with a history of low back pain, neurogenic claudication, radicular pain with single
level canal stenosis and without spinal instability were included in the study. The patients underwent a
thorough preoperative clinical and radiological examination at the department. VAS- Visual Analog Scale
and Oswestry Disability Index and Neck Disability Index (0-10 scale) were used to assess the functional
outcome.
Results: 45 patients were included in our study. 42.2% were between 60-70 yrs. Males were more
compared to females, 82 % people presented with neurogenic claudication pain and the pain was bilateral
in 70 %. The duration was ranging from 6 months to 1 year. The functional outcome analyzed with VAS
and ODI which showed progressive improvement in the values at the end of 1 year follow up the difference
showed a p- value of < 0>
had recurrence of the symptoms and did not develop any spinal instability.
Conclusion: The functional outcome measured with VAS and ODI showed strongly significant as well
as analysis showed immediate improvement with bilateral symptoms, canal stenosis at the L4-5 level.
However good results noted in follow -up with a female who was having bilateral symptoms and stenosis
at L5 S1 level.
