Purpose Of ReviewThe development of truncal and fascial plane blocks has created novel opportunities to apply regional analgesic techniques to patients undergoing spine surgery. This review will summarize recent literature devoted to evaluating candidate blocks for spine surgery, including erector spinae plane block, thoracolumbar interfascial plane block, midpoint transverse process to pleura block, and transversus abdominis plane block. Procedure-specific effects of blocks on patient and healthcare system outcomes will be presented and gaps in care and knowledge will be highlighted.Recent FindingsThe most studied paradigm was bilateral erector spinae plane block for lumbar spine surgery. The most common outcomes assessed were early postoperative pain scores, opioid consumption and related side effects, and length of hospital stay. All candidate blocks were associated with mixed evidence for analgesic and opioid-sparing benefits, and/or reductions in length of hospital stay. The magnitude of these effects was overall small, with many studies showing statistically but not clinically significant differences on outcomes of interest. This may reflect, at least in part, the current state of the (emerging) evidence base on this topic.SummaryOur understanding of the risks, benefits, and value of truncal and fascial plane blocks for spine surgery cohorts is evolving. Although the results derived from this body of literature are encouraging, further research is required before the widespread adoption of specified blocks into spine care can be recommended.Copyright © 2022 Wolters Kluwer Health, Inc.
