Successful Treatment of Lumbar Radicular Pain with Selective Nerve Root Injection Using a Racz Catheter: A Case Report.
Article in Journal of pain research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeLumbar transforaminal selective nerve root injection (SNRI) is effective for controlling radicular pain. However, when a patient occasionally experiences severe foraminal stenosis, osteophytes cover the outside opening of the neural foramen, preventing clinicians from inserting a needle tip within the neural foramen. PATIENTS AND
methodsAn 81-year-old man complained of left L5 radicular pain (left thigh and calf) due to severe left L5-S1 foraminal stenosis. After failure of conventional transforaminal SNRI in the left L5 due to severe degenerative change in the lumbar spine, SNRI was performed using a Racz catheter. After inserting a 16-gauge cannula via the sacral hiatus, the Racz catheter was inserted. The tip of the catheter was positioned near the left L5 nerve root. After confirming the location of the needle tip using a contrast dye, 20 mg (40 mg/mL) of triamcinolone with 0.5 mL of 1% lidocaine and 2 mL of normal saline was injected.
resultsImmediately after the procedure, the patient's pain completely disappeared. During the 1- and 2-month follow-ups, the patient reported only slight pain in the thigh and calf.
conclusionWhen it is not possible to perform a conventional transforaminal SNRI, SNRI using a Racz catheter can be an effective treatment option for controlling lumbar radicular pain.
