Complications during lumbar selective nerve root block: a scoping review.
Article in Acta neurochirurgica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionSelective Nerve Root Block (SNRB) is widely used for managing radicular pain, serving both therapeutic and diagnostic purposes. A complete list of all reported complications associated with SNRB has never been reported.
aimTo map the existing evidence on complications associated with lumbar SNRB.
methodsA scoping review was conducted of peer-reviewed studies on complications associated with transforaminal or foraminal lumbar SNRB in adults with degenerative spine conditions. A systematic search was performed across six databases on 9th of September 2024. Two independent reviewers screened studies for eligibility.
resultsOf the 6,939 screened studies, 118 met the inclusion criteria, comprising a total of 15,817 patients and 72,518 SNRB procedures. A total of 145 distinct complication types and 4,439 complications were identified. Of these, 5.2% were classified as mild/moderate and 0.2% as severe according to the CTCAE grading system. The rate of complications for each study varied substantially, ranging from 0.2% to 73% calculated per procedure. Across all studies, the overall adjusted complication rate was 5.4% per procedure and 5.8% per patient. The most frequent were intravascular injection, vasovagal reactions, and central steroid effect. Severe events, including infection and paralysis, were rare (≤ 0.03%). DISCUSSION AND
conclusionThe SNRB procedure has a low complication rate, with serious complications being rare. This scoping review highlights the heterogeneous complication data in publications. Standardized guidelines for SNRB complication reporting are warranted.
