Spinal Injections: A Narrative Review from a Surgeon’s Perspective

Abstract

Spinal pain is one of most frequent complaints of the general population, which can cause decreased activities of daily living and absence from work. Among numerous therapeutic methods, spinal injection is one of the most effective treatments for spinal pain and is currently widely applied in the clinical field. In this review, spinal injection is discussed from a surgeon’s perspective. Recently, although the number of spinal surgeries has been increasing, questions are arising as to whether they are necessary. The failure rate after spinal surgery is high, and its long-term outcome was reported to be similar to spinal injection. Thus, spinal surgeries should be performed conservatively. Spinal injection is largely divided into diagnostic and therapeutic blocks. Using diagnostic blocks, such as the diagnostic selective nerve root block, disc stimulation test, and diagnostic medial branch block (MBB), the precise location causing the pain can be confirmed. For therapeutic blocks, transforaminal nerve root injection, therapeutic MBB, and percutaneous epidural neuroplasty are used. When unbearable spinal pain persists despite therapeutic spinal injections, spinal surgeries can be considered. Spinal injection is usefully used to identify the precise location prior to a patient undergoing injection treatment or surgery and can reduce pain and improve quality of life, and help to avoid spinal surgery. Pain physicians should treat patients with spinal pain by properly utilizing spinal injection.

Differences between the healthcare systems of Quebec and France for the treatment of pain due to spinal disorders

“…We read the article by Wang et al [ 1 ] with great interest, in which the authors proposed a protocol for physicians to administer ultrasound-guided injections as treatment for spinal pain. Spinal pain is highly prevalent in the general population and often causes substantial suffering, many lost workdays, and high medical costs[ 2 ]. The healthcare system in every country has its preferred treatment strategy for spinal pain.…”
