The Effectiveness of Cervical Transforaminal Epidural Steroid Injection for the Treatment of Cervical Radicular Pain: A Prospective Cohort Study.
In Brief
A Phase 4 clinical trial evaluating Cervical Transforaminal Epidural Injection with dexamethasone sodium phosphate for Cervical Radiculopathy and 2 related conditions. Completed, enrolled 33 participants across 1 site.
Detailed Summary
Study Purpose: 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. Objectives: 1. Determine the proportion of patients with an 80% or greater improvement in arm and neck numerical rating scale pain (NRS) score following an initial cervical transforaminal steroid injection (TFESI) at 4 weeks post-injection and the duration of response up to 12 months. 2. Determine the proportion of patients with a 50%-79% improvement in arm and neck NRS score following an initial cervical TFESI at 4 weeks post-injection and the duration of response up to 12 months. 3. Determine the proportion of patients with less than 50% improvement in arm and neck NRS score following an initial cervical TFESI at 4 weeks post-injection and the duration of response up to 12 months. 4. Determine the proportion of patients with an initial injection plus up to 3 additional injections that maintain 80% or greater, as well as 50-79%, improvement in arm and neck NRS score for up to 12 months. 5. Determine the proportion of patients with a clinically significant change in function defined by a minimally clinically significant change (MCIC) (≥10 point improvement ) or 30% improvement in Neck Disability Index (NDI) score following an initial cervical TFESI at 4 weeks post-injection and the duration of response up to 12 months. 6. Determine the proportion of patients with clinically significant improvement in the Medication Quantification Scale (MQS III) score (≥6.8 point change , equivalent to 10 oral morphine equivalents ) following an initial cervical TFESI at 4 weeks post-injection and the duration of response up to 12 months. 6\. Determine the proportion of patients with clinically significant improvement in the categorical EuroQol 5 Dimensions tool (EQ-5D) defined by ≥0.03 following an initial cervical TFESI at 4 weeks post-injection and the duration of response up to 12 months. 7\. Compare patient demographic, clinical, and imaging characteristics between response groups and perform predictive modeling to better understand variables that increase the likelihood of a successful clinical outcome. 8\. Report adverse effects.

Timeline
Interventions
Transforaminal epidural steroid injection: Injection of 1 to 2 mL of 1% lidocaine to the skin and subcutaneous tissues, a 25-gauge spinal needle will be placed at the level and side of radicular pathology, based on clinical correlation of symptoms/signs and magnetic resonance imaging findings. Advancement to the appropriate target position in the neuroforamen will be performed under fluoroscopic guidance. Satisfactory target position achieved and confirmed in both anterior-posterior and oblique views, 0.5 to 1 mL of contrast will be injected under live fluoroscopic observation with or without digital subtraction angiography depending on suggestion of vascular uptake. Upon confirmation of a satisfactory epidural contrast pattern without vascular uptake, the injectate will be delivered: dexamethasone sodium phosphate 1mL (10mg/mL) and 0.5 ml of 1% preservative-free lidocaine (total volume 1.5 mL).
