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.

Conditions

• Pain
• Radicular; Neuropathic, Cervical

Interventions

Type	Name	Description
PROCEDURE	block with Blunt-type block needle.	Under fluoroscopic guidance, cervical transforaminal epidural injections were performed using 22 gauge blunt needle. The needle position was confirmed using biplanar fluoroscopy and 2 ml of nonionic contrast media was injected to detect intravascular injection.
PROCEDURE	block with sharp-type block needle.	Under fluoroscopic guidance, cervical transforaminal epidural injections were performed using 22 gauge sharp needle. The needle position was confirmed using biplanar fluoroscopy and 2 ml of nonionic contrast media was injected to detect intravascular injection.
