Prevalence of Hallux Valgus in Patients With Femoral Neck Fracture and Its Association With Postoperative Functional Outcomes.
Article in Journal of foot and ankle 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
backgroundHallux valgus is a frequent forefoot deformity in older adults and has been linked to impaired balance, gait dysfunction, and increased fall risk. However, its prevalence among patients with femoral neck fracture and its association with postoperative functional outcomes remain unclear.
methodsThis single-center retrospective study included 235 patients aged ≥ 65 years with available radiographic data who underwent surgery for femoral neck fracture between 2022 and 2024. Hallux valgus was defined on weight-bearing radiographs as a hallux valgus angle (HVA) ≥ 20°. Functional outcomes were evaluated using the Functional Independence Measure (FIM) at 3 months postoperatively. Multivariable linear regression analysis was performed to determine whether hallux valgus was independently associated with motor FIM scores after adjustment for age, sex, surgical procedure, and cognitive function.
resultsAmong the 235 patients with radiographic data, 178 (76%) were women, with a median age of 85 (77-90) years; 86% of patients underwent bipolar hemiarthroplasty. Hallux valgus was present in 55% (130/235), including 20% (47/235) with moderate-to-severe deformity (HVA ≥ 30°). Patients with hallux valgus had significantly lower motor FIM scores at 3 months than those without the deformity (p = 0.044), whereas cognitive and total FIM scores did not differ. In multivariable analysis, hallux valgus (HVA ≥ 20°) was independently associated with lower motor FIM scores (B = -5.92, 95% CI -10.95 to -0.89; p = 0.021).
conclusionsHallux valgus is highly prevalent in patients with femoral neck fracture and is independently associated with lower postoperative motor function. Assessment of hallux valgus may provide additional insight into postoperative functional prognosis in this population.
