Summary

Currently, selective cervical nerve root injections are recommended under the guidance of fluoroscopy, ultrasonography and computed tomography in patients with chronic cervical radicular pain who do not respond to conservative treatments and are not planned for surgery. Various serious complications, mainly vascular, have been reported in the literature. These complications include vertebral artery injury, spinal cord and brain stem infarction. The arteries of the cervical spinal cord are the vertebral, ascending, and deep cervical arteries arising from the aorta.The arteries arising from these main arteries and reaching the intervertebral foramen are called segmental arteries, the arteries reaching the epidural region from the intervertebral foramen and the radicular arteries, and the branches reaching the spinal cord are called the medullary artery. These small arteries supplying the spinal cord lie close to the spinal nerve in the foramen between the anterior and posterior trabercules. Vasospasm or embolism, which occurs as a result of direct needle trauma to these vascular structures around the target nerve or injection of particulate steroids, are the most common causes of complication development.

The aim of our study is to identify the vascular structures around the foramen in selective cervical root injection, which has proven effectiveness in cervical radicular pain, to determine the most reliable method for positioning the needle while reaching the target nerve under US guidance and to prevent possible complications.

Conditions

  • Neck Pain

Interventions

PROCEDURE

Ultrasound-guided selective cervical nerve root block

The volunteer will be placed in the lateral decubitus position with the examined side up and the ultrasonographic examination will be started. Using a high frequency 6-18 MHz linear transducer, scanning in the cephalad and caudal direction until the cervical tubercles are identified in the short axis of the vertebra at the cricoid level, the localization and number of the target nerve root and vascular structures in the foraminal opening between the anterior and posterior tubercles of the transverse process from C4 to C8. will be defined as Unlike healthy volunteers, local anesthetic and steroid injections will be administered to the target nerve.
