Comparison of Tuohy Needle and Quincke Needle During S1 Transforaminal Epidural Injection

Yonsei University Health System (YUHS)

Status: Enrolling

Conditions: S1 Transforaminal Epidural Block

Treatments: Device: Quincke needle group; Device: Tuohy needle group

Study type: Interventional

Funder types: Other

Identifiers

Details and patient eligibility

About

Recently, Park et al. introduced a new technique for performing S1 TFESI using ultrasound. S1 TFESI using ultrasound can be considered to overcome the disadvantages of exposure to radiation. We hypothesized that the frequency of intravascular injection differs depending on the type of needle during S1 TFESI under ultrasound guidance.
