7. Cervical facet pain: Degenerative alterations and whiplash-associated disorder.

Abstract

Introduction: Pain from the cervical facet joints, either due to degenerative conditions or due to whiplash-related trauma, is very common in the general population. Here, we provide an overview of the literature on the diagnosis and treatment of cervical facet-related pain with special emphasis on interventional treatment techniques.

Methods: A literature search on the diagnosis and treatment of cervical facet joint pain and whiplash-associated disorders (WAD) was performed using PubMed, Cochrane, and Embase databases. All relevant literature was retrieved and summarized.

Results: Facet-related pain is typically diagnosed based on history and physical examination of the patients, combined with a diagnostic block (eg, with local anesthetic) of the medial branches innervating the joints. There is no additive value for imaging techniques to diagnose cervical facet pain, but imaging may be used for procedure planning. First-line therapy for pain treatment includes focused exercise, graded activity, and range-of-motion training. Pharmacological treatment may be considered for acute facet joint pain; however, for chronic facet joint pain, evidence for pharmacological treatment is lacking. Considering the lack of evidence for treatment with botulinum toxin, intra-articular steroid injections, or surgery, these interventions are not recommended. Diagnostic blocks are not considered a viable treatment option, though some patients may experience a prolonged analgesic effect. Long-term analgesia (>6 months) has been observed for radiofrequency treatment of the medial branches.

Conclusions: Cervical facet pain is diagnosed based on history, physical examination, and a diagnostic block of the medial branches innervating the painful joints. Conservative management, including exercise therapy, is the first line of treatment. When conservative management does not result in adequate improvement of pain, radiofrequency treatment of the medial branches should be considered, which often results in adequate pain relief.
