Facet and sacroiliac joint pathology are not an uncommon cause of back or neck pain. Imaging-guided techniques provide ready access to these synovial joints. Percutaneous injection of the facet or sacroiliac joints yields important diagnostic information as to whether or not the interrogated joint is involved in the patient's pain syndrome. The injection of a steroid-anesthetic mixture into these joints is capable of providing significant, albeit temporary, pain relief.

Case Reports[Multitruncular block at the elbow for a major hand trauma for prehospital care].
Upper limb peripheral nerve blocks offer many advantages but they are not widely used in prehospital care. We report the case of a multitroncular block at the elbow made by the emergency department team out of the hospital after a major hand trauma. A successful axillary brachial plexus block was done two hours later, without any problem. This case report allows us to discuss about different analgesia techniques useful in prehospital care.

Most local anaesthetic blocks are placed blindly, based on a sound knowledge of anatomy. Very often the relationship between the site of deposition of local anaesthetic and the nerve to be blocked is unknown. Large motor neurons may be stimulated with the aid of an electrical current. ⋯ The accuracy of local anaesthetic blocks can be improved by this technique. By using the lowest possible current a needle could be positioned with in 2-5 mm of a nerve. The correct duration of stimulation ensures that stimulation of sensory nerves does not occur The use of electrical nerve stimulation in veterinary medicine is a novel technique that requires further evaluation.
