Does syndesmotic fixation technique impact complication rates and functional outcomes measured by PROMIS scores following operative repair of ankle fractures?
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. Cited by 5 papers.
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
backgroundIt remains unclear whether syndesmotic fixation technique impacts outcomes following ankle fracture surgery. This study investigates which repair technique, transyndesmotic screws, Suture Button (SB), and suture tape augmentation (STA), results in fewest complications and best functional outcomes measured by Patient Reported Outcome Measurement Information System (PROMIS) computerized adaptive tests (CATs) of physical function (PF) and pain interference (PI).
methods782 patients who underwent ankle fracture surgery at a single institution between 2016 and 2021 were retrospectively reviewed. Two fellowship-trained orthopaedic surgeons independently reviewed all radiographs, determined fixation technique, and assessed complications. Open fractures, pilons, and neuropathies were excluded. 252 had syndesmotic injury identified via intraoperative fluoroscopy. 159/252 who had minimum one-year radiographic follow-up were included for complications analysis. These 159 were sent post-operative PROMIS CATs. 68/159 consented and were included for final analysis of PROMIS. Kruskal-Wallis test compared PROMIS across repair types. Multinomial logistic regression adjusted for propensity scores included as covariates modeled PROMIS by technique.
results62/159 had screw, 59/159 SB, and 38/159 STA. Screw complication rate was 12.9% (8/62): 8.1% (5/62) degenerative joint disease (DJD), 6.5% (4/62) syndesmotic malreduction. SB complication rate was 1.7% (1/59): 1.7% (1/59) DJD. STA had no radiographic complications. Mean PF was 50.5 ± 7.9 screw, 53.9 ± 9.7 SB, and 52.2 ± 13.1 STA (p = 0.72). Mean PI was 49.6 ± 8.2 screw, 47.9 ± 8.8 SB, and 49.2 ± 10.5 STA (p = 0.75). Mean PF was 5.1-points (95%CI: -0.9-11.1) higher for SB and 5.2-points (95%CI: -1.3-11.7) greater for STA vs. screw. Mean PI was 3.2-points less for SB (-3.2, 95%CI:-8.5-2.1) and 4.4-points less for STA (-4.4, 95%CI: -10.1-1.3) vs. screws.
conclusionsSyndesmotic fixation with either SB or STA reduces complications compared to screw. While this study was underpowered to detect differences in PROMIS, improved PROMIS for SB and STA vs. screws suggest that these techniques may result in better functional outcomes compared to screws.
