Lumbar Spinal Stenosis

Brief summary

Percutaneous epidural neuroplasty (PEN) is an effective interventional treatment for radicular pain. But in some cases with wire catheter like Racz catheter, contrast runoffs were not shown to the foramen. This study will show that contrast runoff will affect the results of PEN and in cases which contrast runoff are not shown, additional transforaminal epidural blocks will affect the results of PEN by reviewing medical record, retrospectively.

Detailed description

Medical records will be investigated in cases of PEN with wire type catheter from May 2016 to August 2018. About one hundred cases will be enrolled. Analysis will be performed. It will be compared 1) Success rate of Runoff group and Nonrunoff group in lumbar spine, 2) Success rate of Runoff group and Nonrunoff-NonTransforaminal group in lumbar spine. 3) Success rate of Runoff group with nonrunoff-transforaminal group and Nonrunoff-NonTransforaminal group in lumbar spine. 4) Success rate of Nonrunoff-Transforaminal group and Nonrunoff-NonTransforaminal group in lumbar spine.

Design outcomes

Primary

Measure	Time frame	Description
Success rate of three groups	1 month	Success rate of three groups(Runoff group, Nonrunoff-foraminal group, Nonrunoff-Nonforaminal group) will be compared each other. Success is defined as a 50% or greater reduction in pain score on the pre-procedural Visual Analogue Scale(VAS) score.
