Does lsi treat spinal stenosis?

Not really: I assume by lsi, you are referring to lumbar spinal injections, also known as epidural steroid injections (esis). These can help temporarily treat some of the pain associated with spinal stenosis but are not a definitive treatment. Check out http://www.Mildprocedure.Com for some information on a new minimally invasive procedure for spinal stenosis.

If you mean epidural: If you mean epidural spinal injections, these can work for about 50% of people long term & can be repeated as needed as long as they give good relief for many months or a year or more. Mention of a mild procedure was noted which probably is less effective than injections but there is little data supporting the latter procedure to even evaluate it & it is not marketed to spine surgeons as a rule.

Common option: LESIs are commonly used for conservative treatment of symptomatic spinal stenosis. Check out Spine-health.com.
