Superior reduction quality without improved outcomes: open versus closed reduction for displaced femoral neck fractures in adults under 60 years.
Article in Archives of orthopaedic and trauma surgery, 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
introductionThe optimal reduction strategy for displaced femoral neck fractures (DFNFs) in non-elderly adults remains controversial. Although open reduction may improve radiographic alignment, its impact on outcomes remains unclear. MATERIALS AND
methodsAdults aged < 60 years with DFNFs who were treated with internal fixation between 2017 and 2023 were retrospectively reviewed. Patients were categorized into closed and open reduction groups. Reduction quality was assessed using the Garden alignment index and the Haidukewych reduction criteria. Multivariate analyses were performed for the overall cohort and patients with Pauwels type III fractures. Outcomes included non-union, osteonecrosis, femoral neck shortening, and major reoperations.
resultsIn total, 98 patients were included, among whom 83 and 15 underwent closed and open reduction, respectively. Although open reduction achieved a higher rate of excellent reduction (53.3% vs. 16.9%, p = 0.012), it was not associated with lower rates of non-union or osteonecrosis. In the overall cohort, age was associated with non-union (odds ratio [OR], 1.09; p = 0.024), whereas poorer reduction quality was associated with major reoperation (fair: OR 7.03, p = 0.012; poor: OR 47.6, p = 0.007). In patients with Pauwels type III fractures, poorer reduction quality predicted conversion to arthroplasty (fair: OR 9.84, p = 0.014), and age was associated with non-union and osteonecrosis. Femoral neck shortening of > 10 mm at 3 months was associated with age and open reduction, whereas at 12 months, age and intraoperative blood loss remained significant predictors.
conclusionsOpen reduction achieved a higher rate of excellent reduction but did not reduce complication rates compared with closed reduction. Fracture severity, patient age, and reduction quality remained the principal determinants of outcome, supporting a fracture morphology-guided fixation strategy and realistic patient counseling.
