SPINE INJECTION-TRANSFORAMINAL BLOCK

SUMMARY

1. The transforaminal epidural steroid injection targets injectate delivery to the ventral epidural space.

2. The medication should spread ventrally at the disc/thecal sac interface, medially around the pedicle and enter the epidural space with coverage of the exiting spinal nerve.

3. Avoid the artery of Adamkiewicz which provides vascular supply to the spinal cord from T8 to the conus medullaris, enters the canal via neural foramen T12 through L3.
