Pediatric trigger thumb treated with A1 pulley release with or without postoperative thumb immobilization: a retrospective study.
Article in Journal of orthopaedic surgery and research, 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
backgroundThis study aimed to compare clinical outcomes in patients with trigger thumb who underwent A1 pulley release, with or without postoperative thumb immobilization.
methodsWe retrospectively analyzed 207 patients with trigger thumb, comprising 97 in the splinted group and 110 in the non-splinted group, who underwent surgical treatment at our center. Recurrence rates, differences in extension angles between affected and unaffected interphalangeal (IP) joints, and postoperative complications were compared between the two groups.
resultsAccording to Baek's criteria, all patients except three experienced complete resolution of their symptoms. At the final follow-up, one case of IP joint flexion contracture was observed in the splinted group and two in the non-splinted group, with all cases showing flexion contractures of less than 10°. No recurrences were noted in either group. One case of tendon bowstringing was noted in the splinted group, while two cases were seen in the non-splinted group. The mean difference in extension angles between the affected and unaffected IP joints at the last follow-up was 0.96 ± 1.86° (range: 0-13°) in the splinted group and 1.08 ± 2.06° (range: 0-12°) in the non-splinted group (P > 0.05).
conclusionsOur results suggest that postoperative thumb immobilization following A1 pulley release may not be necessary for patients with trigger thumb, as it does not significantly impact functional outcomes or recurrence rates.
