Spinal stenosis is a narrowing of the spinal canal, which causes mechanical compression of spinal nerve roots. The compression of these nerve roots can cause low back pain and/or leg pain, as well as neurogenic claudication. Lumbar epidural steroid injections have commonly been used in patients with lumbar spinal stenosis. In the cases of refractory to epidural steroid injections, percutaneous epidural adhesiolysis has been used. The aim of our study was to compare the efficacy of balloon neuroplasty (BNP) versus percutaneous epidural neuroplasty using catheter (PEN) for the treatment of patients with lumbar spinal stenosis
This study enrolled 98 patients with lumbar spinal stenosis; 52 patients underwent PEN and 46 underwent BNP. Outcome measures were obtained by visual analogue scale score (VAS) for pain and Oswetry instability index (ODI) at two weeks, and 6 months after treatment.
The mean post-treatment VAS score at 2 weeks and 6 months were statistically significant change compared with pre-treatment VAS in each group. However, VAS difference between 2 groups were not significant. Among the PEN group, 43% of patients had VAS > 50% at both at the 2 weeks and 6 months follow up. Among the patients with BNP group, 39% had VAS values > 50% at 2 weeks and 6 months follow up assessment, respectively.
Both PEN and BNP provide similar outcomes and are reasonable treatment options for carefully selected patients with lumbar spinal stenosis
