Femoral Neck Fracture With Anterior Tilt.
Article in Orthopaedic 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
objectivePosteriorly tilted femoral neck fractures have been extensively studied, whereas anteriorly tilted fractures remain largely unreported. This study aims to characterize the clinical features, radiographic patterns, and postoperative outcomes of femoral neck fractures with anterior tilt.
methodsThis retrospective cohort study included adult patients with OTA/AO type 31B femoral neck fractures who underwent internal fixation within 36 h at a single orthopedic center from 2018 to 2022 and had ≥ 24 months of follow-up. Tilt angle was assessed using preoperative radiographs and CT. Associations between fracture characteristics and postoperative outcomes were examined using univariate and multivariable logistic regression, with covariates selected according to clinical relevance and univariate significance.
resultsAmong 212 patients (median age: 55 years, 53.3% male), anterior tilt fractures were more common in females (57.6%) and those with valgus malalignment (69.7%). Anteriorly tilted femoral neck fractures required a distinct reduction technique compared to conventional femoral neck fractures. Displaced fractures were significantly associated with a higher risk of femoral head necrosis (adjusted odds ratio [aOR] = 4.16; 95% confidence interval [CI] 1.29-13.42; p = 0.017). Stratified analysis revealed that anteriorly tilted femoral neck fractures with varus malalignment-herein referred to as the "anterior-flexion/adduction" subtype-were significantly associated with increased risk of femoral head necrosis (aOR = 7.19; 95% CI 1.12-46.18; p = 0.038).
conclusionsAnterior tilt alone is not a general prognostic risk factor; however, fractures characterized by anterior tilt combined with varus alignment represent a high-risk subtype requiring careful preoperative recognition and treatment planning. Further prospective studies are needed to validate these findings.
