This study is intended to monitor outcomes for 1 year following cervical TFESI. Based on current clinic volume and enrollment rates into a current study of cervical epidural injections that is nearing completion, we conservatively estimate a study enrollment period of 18 months and a total period of 2.5 years from enrollment to final follow-up data collection. If the study were to theoretically start enrolling in July 2019, we would anticipate completion by February 2022. Full story.
