Selective nerve root blocks or transforaminal epidural injections are used for diagnosis and treatment of different spinal disorders. A clear consensus on the use of selective nerve root injections as a diagnostic tool does not currently exist. Additionally, the effectiveness of this procedure as a diagnostic tool is not clear. A systematic review of diagnostic utility of selective nerve root blocks was performed and published in January 2005, which concluded that selective nerve root injections may be helpful as a diagnostic tool in evaluating spinal pain with radicular features, but its role needs to be further clarified. ⋯ Selective nerve root injections may be helpful as a diagnostic tool in evaluating spinal pain with radicular features. However, their role needs to be further clarified by additional research and consensus.

Facet joints are considered to be a common source of chronic spinal pain. Facet joint interventions, including intraarticular injections, medial branch nerve blocks, and neurotomy (radiofrequency and cryoneurolysis) are used to manage chronic facet-mediated spinal pain. A systematic review of therapeutic facet interventions published in January 2005, concluded that facet interventions were variably effective for short-term and long-term relief of facet joint pain. ⋯ With intraarticular facet joint injections, the evidence for short- and long-term pain relief is limited for cervical pain and moderate for lumbar pain. For medial branch blocks, the evidence is moderate for short- and long-term pain relief. For medial branch neurotomy, the evidence is moderate for short- and long-term pain relief.

Randomized Controlled Trial Comparative StudySingle-injection brachial plexus anesthesia for arteriovenous fistula surgery of the forearm: a comparison of infraclavicular coracoid and axillary approach.
The surgical site for the creation of an arteriovenous fistula at the lateral aspect of the distal forearm may be faster and more effectively blocked with the infraclavicular coracoid approach than with the axillary approach for brachial plexus block. ⋯ Blockade of the musculocutaneous nerve developed faster with the infraclavicular coracoid approach than with the axillary approach. The infraclavicular coracoid approach may be preferable in patients scheduled for the creation of an arteriovenous fistula at the forearm.
