In a group of transverse plane at the upper cervical level and assuming a more vertical position at the upper thoracic level. Articular branches may also arise from a communicating loop that crosses the back of the joint between the third occipital nerve and the C2 dorsal ramus [8 , 9]. Beyond the C2–C3 zygapophyseal joint, the third occipital nerve becomes cutaneous over the suboccipi- tal region. Therefore, pain derived from the C2–C3 zygapophy- seal joint can be addressed by blocking the ipsilateral third occipital nerve as it crosses the lateral aspect of the joint, and pain derived from joints below C2–C3 can be addressed by blocking the cervical medial branches as they pass around Vertebral the waists of the articular pillars above and below the cor- artery responding joint [9 ]. Dorsal ramus Biomechanics, Degeneration, Medial branch and Whiplash Injury Cervical facet joints are particularly important in sharing the Ventral ramus axial compressive load on the cervical spine along with the intervertebral disc [10]. The facet joint and capsule are also important contributors to the shear strength of the cervical spine, and resection, displacement, or even facet capsular disruption increases cervical instability [11, 12]. There are mechanistic differences between trauma- related neck pain (whiplash-associated disorders) and degenerative neck problems. Excessive facet joint com- pression and capsular ligament strain have been implicated Fig. The facet joint and capsule are also in close proximity to the semispinalis, mul- tifidus, and rotator neck muscles, and >20 % of the capsule pillars, and have a constant relationship to the bone at the area corresponds to insertion of these muscle fibers into the dorsolateral aspect of the articular pillar as they are bound capsule contributing to injury with excessive muscle con- to the periosteum by an investing fascia and held in place traction as in whiplash injury [14 , 15].

The most common symptom with pain stemming from the The medial branches of the C3 dorsal ramus differ in cervical facet joints is unilateral pain, not radiating beyond their anatomy. The pain often has both static and dynamic waist of the C3 articular pillar similar to other typical medial components. Cervical spine rotation and retroflexion are branches and supplies the C3–C4 zygapophyseal joint. It curves around the lateral and then into the facet joints results in a specific radiation pattern the posterior aspect of the C2–C3 zygapophyseal joint giving (Fig. This is probably a segmental phenomenon 13 Cervical Facet Syndrome: Cervical Medial Branch Block and Radiofrequency Ablation 85 assesses movement of the upper cervical segments. Recent research C2-3 showed that local pressure, defined as pain with pressure of at least 4 kg, is a predictor of success of subsequent C3-4 radiofrequency treatment [19].

Imaging Plain radiography of the cervical spine will show the degen- erative changes and may exclude tumor or fracture. With progressing age degenerative changes are more fre- quently seen: 25 % at the age of 50 up to 75 % at the age of 70 [20]. Degenerative changes of the cervical spinal col- umn can be found in asymptomatic patients, indicating that degenerative changes do not always cause pain.

In daily clinical practice, we consider a • Full neurological examination (sensory, motor, reflexes, diagnostic block successful if more than 50 % pain reduction and gait) is necessary to exclude radiculopathy or other is reported [22, 23 ].

In patients with facet pain, research and clinical experience indicate, however, that after a single block only a small percentage (4 %) of patients have no pain reduction [24]. This means that after a single diag- nostic block, there are only very few false-negative results. In order to minimize the number of false-positives, a number of researchers have suggested that a second block should be carried out using a local anesthetic with different duration of action, e.

Real-time fluoroscopy with contrast injections is essential to detect intravascular injections. Recently some advocate the use of ultrasound as it may help prevent vascular pen- etrations [37]. A report on transient tetraplegia after cervical facet joint injection, performed without imaging, indicates however the vulnerability of the cervical arteries [38].
