The efficacy of threaded Kirschner wire fixation for midclavicular fracture: a single-center retrospective study.
Article in Journal of orthopaedic surgery and research, 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
aimsTo compare the clinical outcomes and complication profiles of open reduction and internal fixation with plate (ORIF-P) versus reduction and internal fixation with threaded Kirschner wire (ORIF-TKW) for midshaft clavicular fractures (MCFs).
methodsA retrospective analysis was conducted on patients with MCFs who underwent either ORIF-P or ORIF-TKW between January 2012 and October 2023. Based on the surgical technique, patients were divided into ORIF-P and ORIF-TKW groups. The two groups were compared in terms of intraoperative blood loss, operative duration, radiographic union duration, shoulder function (Constant-Murley score and Disabilities of the Arm, Shoulder, and Hand [DASH] score), complication rates, and implant removal characteristics.
resultsOf 128 eligible patients, 85 received ORIF-P and 43 received ORIF-TKW. The ORIF-TKW group demonstrated more favorable peri‑operative metrics: shorter operative time (51.5 ± 6.4 vs. 63.6 ± 5.7 min, p < 0.001), less blood loss (38.7 ± 5.6 vs. 56.2 ± 10.1 ml, p < 0.001), and smaller incision length (3.9 ± 0.7 vs. 8.8 ± 0.9 cm, p < 0.001). Radiographic union occurred earlier in ORIF-TKW (median 5.0 vs. 6.0 months, p < 0.001). All 43 patients in the ORIF‑TKW group underwent planned implant removal, with minimal operative time and blood loss, whereas in the ORIF‑P group, only 50 patients (58.8%) underwent removal, exclusively for symptomatic reasons or patient request, with significantly more invasive removal procedures (p < 0.001). Functional outcomes at 6 months were equivalent. Complication rates did not differ significantly between groups. Two refractures in the ORIF P cohort were successfully revised using ORIF TKW.
conclusionIn this single-center retrospective study, ORIF-TKW was associated with superior peri-operative outcomes, earlier radiographic union, and a less invasive planned removal procedure compared with ORIF-P, while functional recovery was similar. A post-hoc analysis demonstrated statistical comparability in fracture complexity within the 2B subgroup, partially mitigating concerns regarding selection bias. However, these findings remain hypothesis-generating and subject to residual confounding; prospective randomized trials with stratification based on fracture morphology are required before any change in routine practice can be recommended. The limited revision experience (2 cases) is insufficient to endorse threaded K-wire fixation as a routine salvage strategy.
