Incidence and risk factors for fixation failure of femoral neck fractures in adults: a single-center multifactorial analysis.
Article in Langenbeck's archives of surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveTo identify risk factors for fixation failure, avascular necrosis (AVN), and nonunion after reduction and internal fixation of femoral neck fractures in adults.
methodsThis single-center retrospective study included 217 adult patients who underwent reduction and internal fixation for femoral neck fractures between January 2012 and December 2023. Demographic variables, comorbidities, smoking status, excessive alcohol consumption, mechanism of injury, fracture type, time interval from injury to operation, fixation method, reduction quality, and implant removal were extracted from medical records. Outcomes (fixation failure, AVN, and nonunion) were ascertained during follow-up. Multivariable logistic regression was used to identify factors associated with each outcome.
resultsAmong 217 patients, fixation failure occurred in 24.0% (n = 52), AVN in 14.3% (n = 31), and nonunion in 9.7% (n = 21). Fixation failure was associated with displaced fracture pattern (Garden III/IV) (OR = 3.314, P = 0.007), poor reduction quality (OR = 2.571, P = 0.036), and excessive alcohol consumption (OR = 3.510, P = 0.010). AVN was associated with excessive alcohol consumption (OR = 5.603, P = 0.002), Garden III/IV fractures (OR = 3.802, P = 0.023), and poor reduction quality (OR = 4.020, P = 0.006). Cannulated screw fixation (OR = 0.255, P = 0.014) and earlier surgery (≤ 1 day: OR = 0.100, P = 0.006; 1–3 days: OR = 0.307, P = 0.028) were associated with lower odds of nonunion.
conclusionIn adult femoral neck fractures treated with internal fixation, fracture displacement, poor reduction quality, and excessive alcohol consumption were independently associated with fixation failure and avascular necrosis. Earlier surgery was associated with reduced odds of nonunion. Cannulated screw fixation was also associated with lower odds of nonunion versus other methods, although residual confounding cannot be excluded. These findings highlight the importance of optimizing reduction quality and addressing modifiable risk factors to improve outcomes. LEVELS OF EVIDENCE: Level III
