ABSTRACT

Objective:

Lumbar spinal stenosis is a frequent cause of back and leg pain in patients over 50. Stenosis can be caused by congenital lesions or degenerative changes. Degenerative spinal stenosis may be due to intervertebral disk bulging, joint facet hypertrophy, thickening of the ligamentum flavum and spondylolisthesis.

Materials and Method:

We observed 28 patients retrospectively. All patients have back and/ or leg pain with neurogenic claudication. The patients were scored by numerical pain scale with zero to ten that zero is no pain and ten is the worst. During the surgeries all stenosis levels treated by unilateral approach with bilateral microdecompression.

Results:

At the end of 1 month follow up, all of the patients got rid of the neurogenic claudication. The pain release rate was 86%.Many literature analysis results are similar when inspected.

Conclusions:

The main point of the unilateral approach bilateral microdecompression for treating lumbar spinal stenosis is minimal invasive surgery with satisfactory decompression.
