Ultrasound-Guided Interventions of the Cervical Spine and Nerves.

High-resolution ultrasound (US) enables prompt depiction of muscles, tendons, ligaments, and peripheral nerves. It seems to be the best imaging modality for guiding perineural injections. The most complicated neurovascular network of the musculoskeletal system surrounds the cervical spine; so injection to that region is never an easy task. This article elaborates the regional anatomy and the use of US scanning and guidance for cervical interventions; for example, cervical root, superficial cervical plexus, stellate ganglion, cervical medial branch, greater occipital nerve, and third occipital nerve. The article aims to lead readers to practice US-guided cervical injections precisely and safely.
