Delayed vascular complication after collagenase injection for Dupuytren disease.
Article in BMC musculoskeletal disorders, 2023. 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
backgroundVascular adverse events after collagenase injection for Dupuytren disease are absent in large trials and systematic reviews. The aim of this study is to present a case series of delayed vascular complications after collagenase treatment.
methodsA prospective evaluation of 1181 consecutively treated patients at one orthopedic department identified three patients reporting symptoms of possible vascular complication. Baseline demographics and description of symptoms were collected, with a physical examination documenting extension deficit and neurovascular status. All patients completed the Cold Intolerance Symptom Severity (CISS) scale (range 4-100, lower is better) and underwent Doppler sonography examination of the digital arteries.
resultsAll patients were treated in the small finger and two had an isolated proximal interphalangeal joint contracture. All patients had a delayed presentation of a few months, with episodes of white discoloration of the treated finger relieved within 30 min and associated with variable pain, paresthesia, stiffness and weakness. Two of the patients reported cold exposure as an episode trigger and had a pathological CISS score (40 and 36, respectively). Doppler sonography identified a nonpatent ulnar digital artery in one patient.
conclusionsDelayed vascular complication after collagenase treatment is rare, but surgeons and patients should be aware of the risk, especially when treating the small finger.
