About

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.

Full 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.

Enrollment: 100 estimated patients

Sex: All

Ages: 20 to 80 years old

Volunteers: No Healthy Volunteers

Trial design

100 participants in 3 patient groups

Runoff Group

Description:

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

Nonrunoff-Transforaminal group

Description:

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

Treatment:

Procedure: Transforaminal Block

Nonrunoff-NonTransforaminla group

Description:

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