Selective Nerve Root Injections Can Predict Surgical Outcome For Lumbar and Cervical Radiculopathy

Abstract: Our study found that a diagnostic SNI can safely and accurately discern the presence or absence of cervical or lumbar radiculopathy. The diagnostic SNI can persuade surgeons from operating on an initially suspicious, but incorrect, level of radiculopathy. In cases where MRI findings are equivocal, multilevel, and/or do not agree with the patient's symptoms, the result of a negative diagnostic SNI (ie, lack of presence of radiculopathy) becomes superior in predicting the absence of an offending lesion.

“…28,38,40,41 Needle provocation of the nerve root was conducted in four studies. 28,38,40,41 Similarly, three studies 28,38,39 carried out up to three control injections at adjacent asymptomatic levels (two 38,39 being the within-patient case-control studies). The third 28 used the control injections in order to try to increase the sensitivity and specificity of patient responses to injections at the level thought to be symptomatic.…”

“…[4][5][6][7][8][9] In addition, studies have supported the relevance of selective nerve root blockade to clinical and MR imaging findings. 10,11 Various techniques have been described for the transforaminal or selective cervical nerve block, but there is agreement that image guidance is imperative for both accuracy and safety. 1,[12][13][14][15][16][17] Imaging techniques include CT, 14,15,18 CT fluoroscopy, 19,20 and fluoroscopy.…”

“…The terms foraminal block and SNRB are often interchanged and comparisons are drawn between the two. Despite this, however, a good correlation with SNRB as compared to operative findings and surgical outcome has been shown [13][14][15][16]. A number of studies have also demonstrated improved accuracy of SNRB using smaller volumes of injectate [10,17].…”
