Abstract
I
n conclusion, we have found that decompression alone without instrumented fusion in patients complaining of DLSS without spondylolithesis or any element of instability is effective as decompression and instrumented fusion with no need for further extensive surgery in old people who already have multiple co-morbidities and mortalities.
The main challenge in the operative treatment of spinal stenosis is to provide adequate decompression while maintaining stability. Extensive laminectomy and facetectomy provide sufficient decompression in central and lateral stenosis. However, the mechanical integrity of the lumbar spine may be severely impaired.
On the basis of our results, we do not believe that arthrodesis is justified in the absence of detectable segmental instability.
Decompression (especially minimal invasive) is an effective surgical option for treating patients suffering from lumbar canal stenosis as it improves the quality of life with no superiority can be got by further extensive operation (instrumented fusion) which have more blood loss, longer duration of operation, hospital stay and additional costs.
