O-Arm CT-Guided Intercostal Nerve Radiofrequency Ablation for Refractory Tietze's Syndrome: A Case Report.
Article in Orthopedic research and reviews, 2026. 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
Background: Tietze's syndrome is a rare inflammatory condition of the anterior chest wall that may cause chronic localized pain resistant to conservative treatment. Surgical cartilage resection often provides only temporary relief, and recurrence of pain presents a significant therapeutic challenge. Case Presentation: We report the case of a 49-year-old female with recurrent anterior chest wall pain due to refractory Tietze's syndrome following two costal cartilage resections. Despite corticosteroid injections and physiotherapy, pain persisted with a VAS score of 7-8/10. Considering multiple treatment failures, O-arm CT-guided radiofrequency ablation (RFA) of the intercostal nerves at the 2nd-3rd ribs was performed. The procedure allowed precise cannula placement under 3D visualization and correction of intrathoracic misplacement detected on intraoperative O-arm CT (not evident on conventional fluoroscopy). After final lesioning at 80 °C for 90s, the patient experienced complete pain relief (VAS 0-1/10), restored respiratory comfort, and full functional recovery without complications. Conclusion: O-arm CT guidance enables accurate targeting and improved safety during intercostal nerve RFA in anatomically complex anterior chest wall regions. This technique represents a promising minimally invasive option for refractory Tietze's syndrome when surgery and conservative therapy fail.
