Whiplash-associated disorders are comprised of a range of symptoms of which neck complaints and headaches are the most significant spine related. In the acute and sub-acute stage of the disorder, conservative treatment for minimally 6 months is recommended, active mobilization is slightly better than passive treatment. ⋯ The available evidence for injection of Botulinum toxin A (2 B-) and intra-articular corticosteroid injections (2 C-) supports a negative recommendation. Radiofrequency treatment of the ramus medialis (medial branch) of the ramus dorsalis is recommended (2 B+).

This case report describes an ultrasound approach to the transversus abdominis plane (TAP) local anesthetic block. This block induces sensory blockade in the lower half of the abdomen where the pulse generator or the infusion pump is to be housed in a subcutaneous pocket, and therefore provides an alternate to general anesthesia or administration of high-dose local anesthetics. ⋯ TAP block can be a potentially useful substitute to general anesthesia or local anesthesia for the pocket formation in neuromodulation techniques, and it provides adequate anesthesia of the abdominal wall. This block is potentially an important addition to the monitored anesthesia care protocol.

More than 50% of patients presenting to a pain clinic with neck pain may suffer from facet-related pain. The most common symptom is unilateral pain without radiation to the arm. Rotation and retroflexion are frequently painful or limited. ⋯ Therapeutic repetitive medial branch blocks, with or without corticosteroid added to the local anesthetic, result in a comparable short-term pain relief (2 B+). Radiofrequency treatment of the ramus medialis of the cervical ramus dorsalis (facet) may be considered. The evidence to support its use in the management of degenerative cervical facet joint pain is derived from observational studies (2 C+).

Occipital neuralgia is defined as a paroxysmal shooting or stabbing pain in the dermatomes of the nervus occipitalis major and/or nervus occipitalis minor. The pain originates in the suboccipital region and radiates over the vertex. A suggestive history and clinical examination with short-term pain relief after infiltration with local anesthetic confirm the diagnosis. ⋯ There is no evidence to support pulsed radio-frequency treatment of the ganglion spinale C2 (dorsal root ganglion). As such, this should only be done in a clinical trial setting. Subcutaneous occipital nerve stimulation can be considered if prior therapy with corticosteroid infiltration or pulsed radio-frequency treatment failed or provided only short-term relief (2 C+).

The management of chronic pain remains a challenge because of its complexity and unpredictable response to pharmacological treatment. In addition, accurate pain management may be hindered by the prejudice of physicians and patients that strong opioids, classified as step 3 medications in the World Health Organization ladder for cancer pain management, are reserved for the end stage of life. Recent information indicates the potential value of strong opioids in the treatment of chronic nonmalignant pain. ⋯ However, those recommendations are often based on data derived from studies designed to evaluate acute pain relief, and sometimes on single dose studies, which reduces this information to the level of an indication. In daily practice, the clinician needs to titrate the optimal dose during the opioid rotation from a reduced calculated dose, based on the clinical response of the patient. Further research and studies are needed to optimize the equianalgesic dosing tables.
