Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Runoff Group

Runoff group are the patients whose images were shown root shadow by contrast media.

No interventions assigned to this group

Nonrunoff-Transforaminal group

Nonrunoff-Transforaminal group are the patients whose images are not shown root shadows by contrast media, so additional transforaminal blocks are done.

Transforaminal Block

Intervention Type PROCEDURE

Epidural block via neural foramen of lumbar spine

Nonrunoff-NonTransforaminla group

Nonrunoff-NonTransforaminal group are the patients whose images are not shown root shadows by contrast media, but no additional transforaminal blocks are done.

No interventions assigned to this group
