Objective
To evaluate the efficacy of epidural injection for spinal stenosis with symptoms of low back pain, pseudoclaudication, or radiating pain.

Method
Thirteen patients with spinal stenosis which were confirmed by the computed tomography (CT) studies were treated with epidural injections of steroids and local anesthetics for three times with 1 week interval. The efficacy of epidural injection was assessed by visual analogue scale (VAS), pain rating score (PRS), treadmill test, and jump test.

Results
1) The VAS, PRS, pain free walking distances, and jump heights were checked right before injection, and at 1 week and 3 months after injection. The VAS and PRS were significantly decreased after epidural injection. The pain free walking distances and the jump heights were significantly increased after epidural injecton.

Conclusion
Epidural injections of steroid and local anesthetics are effective in the short term period, but also in the long term period for patients with spinal stenosis.
