U.S., April 16 -- ClinicalTrials.gov registry received information related to the study (NCT07531485) titled 'The Selective Intraperineural Nerve Root Block Study' on April 05.
Brief Summary: Before lumbosacral decompression surgery for radicular pain, selective nerve root block(SNRB) is a common procedure to identify the responsible compressed nerve root(RCNR) and predict surgical outcomes. However, the diagnostic accuracy of conventional SNRB is unsatisfactory, especially in terms of specificity. The main limitation is the uncontrolled distribution of anesthetics during injection: when anesthetics spread to surrounding soft tissues instead of acting directly on the RCNR, false-negative results may occur with persistent radicular pain; wh...
