Summary

Cervical facet joints have been implicated as a source of chronic pain in 54-67 % patients with chronic posterior neck pain.1 Intraarticular injections, medial branch nerve blocks and neurolysis of medial branch nerves have been described in managing chronic neck pain of facet joint origin.2 The evidence for long-term therapeutic benefits of intraarticular injections of facet joints is limited. Medial branch nerve blocks show moderate evidence of long-term benefit with evidence of side effects.3 Paraneuraxial nerve blocks have become very popular clinically, due to their clinical and anatomical characteristics. These techniques are comparable to neuraxial nerve blocks in terms of success rate and analgesic efficacy and may confer many of advantages over neuraxial nerve blocks.4 Retrolaminar blocks are among this family that are near but not within the neuraxis like spinals or epidurals.5 Most reports and studies of retrolaminar blocks have been in the context of anesthesia for truncal surgery and truncal pain syndromes (thoracic and abdominal).6 Postoperative and pain treatment cervical retrolaminar blocks studies are currently sparse.7 The major advantage of this technique is minimizing or even eliminating the risk of pneumothorax. Additionally, the risks of nerve root damage and inadvertent injection into a dural sleeve, an intervertebral foramen, or the epidural or intrathecal spaces should also be decreased.8

Conditions

Interventions

OTHER

Retrolaminar block

2- Cervical retrolaminar block: will be performed on prone-positioned patients. Under fluoroscopic visualization, after identification of the lamina at the desired level, a 25-gauge, 3.5-inch spinal needle was introduced and when the needle tip will be confirmed at the posterior aspect of the cervical lamina corresponding to cervical facet arthropathy level. 5 mL of a mixture of 3 mL 1% lidocaine and 2 mL dexamethasome (8mg/2ml) will be injected.

OTHER

Medial Branch Block

1- Cervical medial branch block: will be performed on prone-positioned patients using a posterior approach. Under fluoroscopic visualization, after identification of the waists of the articular pillars at the desired levels, each medial branch block was administered with a 25-gauge, 3.5-inch spinal needle. When the place of the needle tip will be confirmed at the mid-point of the waists of articular pillars, 1 ml of the mixture of 0.5 mL 1% lidocaine and 0.5 mL dexamethasome (8mg/2ml) will be injected at each level.
