Ultrasound-guided minimally invasive interventions for refractory musculoskeletal pain: a real-world study from an interventional rheumatology unit.

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: Chronic musculoskeletal pain represents a global health challenge, with a substantial proportion of patients failing to achieve adequate symptom control despite conventional treatment. Interventional rheumatology units (IRUs) incorporating ultrasound-guided minimally invasive procedures have emerged as a promising strategy for the management of refractory musculoskeletal pain. However, real-world evidence regarding the performance of these units in routine clinical practice remains limited. This study evaluated the effectiveness and safety of an IRU in routine clinical practice. Methods: This retrospective, observational, single-center study included consecutive patients with chronic musculoskeletal pain refractory to conventional treatment, who underwent ultrasound-guided interventions at an IRU between April 2023 and February 2026. Procedures were categorized as myofascial infiltrations, shoulder procedures, erector spinae plane block, and a miscellaneous group of other procedures. The primary outcome was a clinically meaningful pain reduction, defined as a reduction of at least 2 points on the Numerical Rating Scale (NRS) at the first post-procedure follow-up visit. Results: A total of 170 patients (77.6% women; median age 61 years) were included. Overall, 125 of 170 patients (73.5%) achieved the primary endpoint, with no significant differences across procedural groups. Median NRS decreased from 7.0 [IQR, 7.0-8.0] to 3.0 [IQR, 2.0-6.0] at follow-up, corresponding to a median reduction of 4.0 points (IQR, 1.0-6.0; Conclusion: Ultrasound-guided minimally invasive procedures performed within an IRU were associated with high rates of clinically meaningful pain reduction, and a favorable safety profile in patients with chronic musculoskeletal pain. These findings suggest that IRUs may have a role within multidisciplinary pain management pathways, although prospective controlled studies are needed to confirm these results.
