1 · What the graph read from it

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.

2 · The registry

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

purposeSupracondylar fractures of the distal humerus are among the most common pediatric fractures. For unstable fractures, reduction with pin fixation and postoperative immobilization is standard, but the optimal duration of pin fixation and splinting remains uncertain. This study evaluated whether pin and splint removal approximately 3 weeks after surgery was associated with secondary fracture displacement in children treated for displaced supracondylar humeral fractures.

methodsWe retrospectively reviewed pediatric patients surgically treated for displaced supracondylar humeral fractures at our institution between January 2015 and December 2024. Both closed and open reduction cases were eligible. Collected data included demographics, Rigault-Lagrange fracture stage, fixation construct, duration of pin and splint immobilization, radiographic displacement before and after removal, and postoperative complications.

resultsA total of 211 patients were included (mean age 6.5 ± 2.3 years). According to the Rigault-Lagrange classification, 87 fractures were stage 2, 54 were stage 3, and 70 were stage 4. Pins and splints were removed after a mean of 23.6 ± 4.0 days. Secondary radiological displacement was observed in 11 patients, corresponding to 13 displacement events: 10 occurred before pin removal and 3 after removal. Three patients showed a change in Baumann's angle greater than 12° after removal, and no patient lost intersection of the anterior humeral line with the capitellar ossification center after removal. One patient required early revision before pin removal, and no patient required delayed corrective osteotomy.

conclusionIn this retrospective cohort, pin and splint removal approximately 3 weeks after surgical fixation of pediatric supracondylar humeral fractures was associated with a low rate of subsequent secondary displacement, irrespective of fracture stage. Most displacement events occurred before pin removal, and no patient required delayed corrective osteotomy. Early removal may limit exposure to complications associated with prolonged pin fixation and immobilization, although this potential benefit requires confirmation in comparative studies. LEVEL OF EVIDENCE: III (retrospective cohort study).
