- Abstract: BACKGROUND: Cervical epidural injection, performed via the interlaminar approach, represents a useful interventional pain management procedure indicated in patients with a cervical herniated disk. Due to thedecreased epidural space in the cervical region, cervical epidural injections may result in potentially serious complications, especially during a large volume injection. METHODS: Thirty-four patients with neck pain due to a cervical herniated disk that were referred to the pain clinic for cervical epidural steroid injection were randomized into two groups. One group received a cervical epidural injection of 4 ml drug and the other group received 2 ml drug. The injected mixture included triamcinolon, ropivacaine and omnipaque. Spread levels of the drug after injection were estimated with the use of C-arm fluoroscopy. RESULTS: Spread levels to the cephalad for patients in the two groups were 4.88 +/- 0.78 segments and 4.53 +/- 0.49 segments, respectively. Spread levels to the caudad for patients in the two groups were 4.59 +/- 0.93 segments and 4.47 +/- 0.51 segments, respectively. The results showed no significant difference in the spread level between the two groups. CONCLUSIONS: Use of a small volume of drug (2 ml) can provide a sufficient spread level of the injected drug that is desirable for patients with a cervical herniated disk.
