Study Overview
Brief Summary
This study evaluates the incidence of intravascular injection during cervical transforaminal epidural block using blunt needle, compared to the sharp needle. The investigators will performed cervical transforaminal epidural block using blunt-type block needle in half of participants or sharp-type block needle in the other half.
Detailed Description
Cervical transforaminal epidural block is an effective treatment option of radiating pain. There are potential risks associated with transforaminal epidural block such as infection, dural puncture, bleeding, and intravascular injection. Although the risk is low, intravascular injection should be carefully monitored because intravascular injection of particulate steroids can cause fatal neurologic deficits such as spinal infarction and cerebral infarction.
The incidence of intravascular injection during transforaminal epidural block with real time fluoroscopy guidance depends on spinal level. The previous studies using real time fluoroscopy demonstrated that the incidence of intravascular injection of cervical transforaminal epidural block is higher than that of lumbosacral transforaminal epidural block.
In this study, therefore, the investigators investigate the incidence of intravascular injection during cervical transforaminal epidural block using blunt needle, compared to the sharp needle.

Arms & Interventions

Intervention: block with sharp-type block needle. (Procedure)
Outcomes
Primary Outcomes
Intravascular injection
Time Frame: During procedure
Intravascular injection was defined as contrast media spreading out through the vascular channel during injection of contrast media under real time fluoroscopy. The investigators observed the intravascular injection during the procedure. The intravascular injection rate was calculated based on the total number of treated levels.
Secondary Outcomes
- Needling time(During procedure)
