About

The goal of this observational study is to compare in intravasation rate during S1 transforaminal epidural injection between using a straight needle and a curved needle. The main question it aims to answer are:

The main question it aims to answer is:

• whether there is a difference in intravascular rate between using a straight needle and a curved needle in S1 transforaminal epidural injection

Participants in this study will be randomly assigned to receive an S1 transforaminal epidural injection using either a straight needle or a curved needle. The researchers will then observe the intravasation rate and compare it between the two groups.
