Cervical interlaminar epidural injections are performed frequently in managing chronic neck and upper extremity pain, although less commonly than lumbar interlaminar epidural injections. Recently, the US Food and Drug Administration warnings and safeguards to prevent neurologic complications. These were developed by the Multi-Society Pain Workgroup have taken center stage for all types of epidural injections, including cervical interlaminar epidural injections. The recommendations of safeguards to prevent neurologic complications after epidural steroid injections include that cervical interlaminar epidural injections must be performed utilizing fluoroscopy with anteroposterior, lateral, or oblique views with injection of contrast medium and that entry be limited to the C7-T1 epidural space or occasionally the C6-C7 with requirements for magnetic resonance imaging assessment of the epidural space. ⋯ This study illustrates that dural puncture is equally prevalent, though very rare, irrespective of the needle entry level into the epidural space, with an overall dural puncture rate of 1.4%, with 1.8% at the C5-C6 level, 0.87% at the C6-C7 level, and 1.71% at the C7-T1 level. Based on the present literature, it appears that performing the procedure by inserting the needle into the cephalic portion of the intervertebral space rather than the caudal portion may be safer.
