The above findings confirm the effectiveness of TFESIs in properly selected patients and are consistent with findings of Vad VB and Ahadian, Farshad
We hypothesized that while performing the S1 TFESI in the AP view, locating the needle at the medial side of S1 foramen might decrease the incidence of intravascular injection, similar to the Scotty dog approach.
The results of previous studies have indicated that because the vascular contrast pattern appears and disappears quickly during TFESI, live fluoroscopy should be used to observe the dynamic contrast flow [7].
The patterns of the epidural spread of the contrast medium were also compared between the medial and lateral approaches, and contrast volumes required for therapeutic S1 TFESI were identified.
Patients were randomized to lumbar TFESI or insterspinous sham injection.
A prospective, randomized, controlled, double-blinded trial conducted by Riew and associates (8) supports the use of TFESI as a nonoperative modality that has the potential of avoiding surgery for lumbar radiculopathy.
Additional studies have shown that lumbar TFESI injections have good short-term outcomes in the setting of lumbar disc herniation9 and spinal stenosis.
To date, there have been few studies observing pain provocation in TFESI and these studies have reported no significant difference.
The above-mentioned interventions such as TFESI, caudal and interlaminar injections are some of the available treatment methods used for this aim.
In our study, 100 patients were taken for TFESI in the age group of 20-60 years.
