Ultrasound-guided neuromodulation for neuropathic pain after radial forearm flap reconstruction: a case report.
Article in Pain management, 2025. 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
Neuropathic pain is a common complication following radial forearm free flap (RFFF) reconstruction, often associated with damage to the superficial branch of the radial nerve (SBRN) and lateral antebrachial cutaneous nerve (LACN). Traditional treatment approaches, including pharmacologic and non-pharmacologic interventions, frequently provide incomplete pain relief. This case report describes the innovative use of ultrasound-guided musculocutaneous and SBRN blocks combined with pulsed radiofrequency (PRF) neuromodulation in a 70-year-old male with severe neuropathic pain following RFFF for tongue carcinoma reconstruction. The intervention provided immediate and complete pain relief, maintained for three days post-procedure. Partial symptom improvement persisted beyond the initial phase. Although complete pain relief was not sustained over the longer term, the significant initial response confirmed the targeted nerves as viable candidates for neuromodulation. This confirmation opens potential pathways for exploring longer-lasting neuromodulation techniques, such as cryoneurolysis or peripheral nerve stimulation, to achieve sustained pain relief. Further research into these modalities is recommended to optimize long-term outcomes for patients experiencing neuropathic pain post-RFFF reconstruction.
