Brief Summary

Early epidural space identification is critical to the efficacy and safety of cervical epidural steroid injections (CESI) \[1\]. Currently, the accepted method for epidural space recognition is the loss of resistance technique (LORT). I perform CESIs with fluoroscopy only \[2\]. I hypothesized that the contrast spread technique (CST) might recognize epidural space concurrently with or sooner than LORT. I also suggested that smaller needles might be employed with CST but not with LORT. To test my hypotheses, I conducted a comparison study.

Outcome Measures

Primary Outcomes (2)

  • Confirmation of the LOR with epidurally located 18G Tuohy needle by the Epidrum device.

    Cervical epidural procedure and epidural space recognition were performed utilizing the fluoroscopy only method. With this technique, needle navigation from the skin toward the epidural space is performed under contralateral oblique fluoroscopy. With the needle at the ventral interlaminar line, the contrast spread technique was employed for epidural space identification. After radiological confirmation of the epidural spread, LOR was tested using an Epidrum® device (Exmoor Innovations Ltd., Somerset, UK). Subsequently, accompanied by the radiology assistant, I observed the Epidrum for 30 seconds or more; if the Epidrum deflated, thus confirming LOR, the result was positive. However, if the device remained inflated, the result was reported as negative.

Study Arms (2)

18 Gauge Tuohy group

ACTIVE COMPARATOR

In the 18G group, all CESIs were performed utilizing the fluoroscopy only method when the needle was navigated from the skin toward the epidural space under contralateral oblique fluoroscopy, and the contrast spread technique was employed for epidural space identification. After radiological confirmation of the epidural spread, LOR was tested using an Epidrum® device (Exmoor Innovations Ltd., Somerset, UK).

Procedure: Epidural space identification with cervical epidural steroid injection employing CST and LORT.

25 Gauge Tuohy group

ACTIVE COMPARATOR

In the 25G group, all CESIs were performed utilizing the fluoroscopy only method when the needle was navigated from the skin toward the epidural space under contralateral oblique fluoroscopy, and the contrast spread technique was employed for epidural space identification. After radiological confirmation of the epidural spread, LOR was tested using an Epidrum® device (Exmoor Innovations Ltd., Somerset, UK).
