Delayed extensor pollicis longus tendon rupture after minimally displaced distal radius fracture: a report of two cases.

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
Introduction: Extensor pollicis longus (EPL) tendon rupture is an uncommon but serious complication following nondisplaced or minimally displaced distal radius fractures. Case presentation: We present two cases of delayed EPL tendon rupture. A 61-year-old woman and a 41-year-old man both developed inability to extend the thumb several weeks after conservative treatment of minimally displaced distal radius fractures. Intraoperative findings revealed poor tendon quality and significant retraction. Both patients were managed with palmaris longus tendon graft using the Pulvertaft weave technique. Outcomes: At 10 months, PRWHE improved from 48 to 10, exceeding the ≈ 14-point MCID; Kapandji improved from 6 to 9 on the operated side and matched the contralateral hand. Conclusion: Rupture of the EPL tendon after minimally displaced distal radius fracture is a rare but clinically significant complication with major impact on hand function. Delayed EPL rupture may present 3-12 weeks after minimally displaced distal radius fractures; prompt recognition of progressive loss of active IP extension is essential. When direct repair is not feasible and stumps are available, palmaris longus intercalated grafting offers reliable recovery while preserving independent index extension.
