Surgical timing and outcomes after volar plate fixation of distal radius fractures: A matched cohort study.
Article in PloS one, 2026. 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
backgroundThe impact of surgical timing on outcomes in orthopedic trauma surgery remains controversial. While most evidence derives from hip fractures and other major injuries, data on distal radius fractures is limited. This study aimed to assess whether surgical timing influences operative duration, reduction quality, complication rates, and functional outcome after operative treatment of distal radius fractures.
methodsThis single-center, retrospective study included patients aged ≥ 16 years who underwent surgical treatment for distal radius fractures at our hospital between 01.01.2016 and 31.12.2024. Patients without postoperative radiographic follow-up, those treated conservatively, or those managed by other departments were excluded. Patients were grouped according to surgical timing into regular-hours surgery (08:00-16:00) and out-of-hours service. A 1:1 matched cohort analysis was performed with criteria being AO/OTA fracture classification and propensity scoring for age and sex. Analyses were stratified by AO/OTA fracture type (A, B, and C). Outcomes included operative time, radiographic reduction quality, complication rates, and functional outcome assessed by postoperative range of motion.
resultsA total of 660 patients were included, of whom 434 underwent surgery during regular hospital hours and 226 during out-of-hours service. From the out-of-hours cohort, matching was performed using an exact match for fracture morphology according to the AO/OTA classification and propensity score matching for age and sex, resulting in two well-balanced 1:1 matched groups comprising 128 patients each. Across both groups, operative duration, reduction quality, complication rates, and functional outcome assessed by postoperative range of motion did not differ between regular-hours and out-of-hours surgery.
conclusionSurgical timing was not associated with differences in operative duration, reduction quality, complication rates, or functional outcome after operative treatment of distal radius fractures. Within this matched cohort, no measurable differences were detected between regular-hours and out-of-hours surgery. As the study was not designed to establish equivalence, these findings indicate the absence of a detectable difference in this specific institutional setting and should not be interpreted as support for routine out-of-hours fixation.
