Comparison of short-term costs and 3-year complications in geriatric femoral neck fractures: hemiarthroplasty versus total hip arthroplasty.
Article in BMC musculoskeletal disorders, 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
backgroundHemiarthroplasty (HA) and total hip arthroplasty (THA) are the primary surgical options for geriatric femoral neck fractures (FNF). Our study balanced heterogeneity in baseline patient conditions and included long-term follow-up data, compared short-term costs and reoperation risks within the 3-year period, aimed to provide evidence for personalized surgical selection.
methodsThis study enrolled 878 patients aged ≥ 60 years with first-time FNF treated at the Orthopedics Department of a large Grade-Three Class-A Hospital in China (2013.03–2021.12), categorized into HA and THA groups. Collected demographic characteristics and relevant clinical data, and Inverse Probability of Treatment Weighting (IPTW) was applied to adjust for baseline heterogeneity. Primary outcomes encompassed prosthesis-related complications, secondary fractures included contralateral fracture and osteoporotic vertebral compression fracture (OVCF), and short-term costs. Subgroup analyses stratified by age (60–75 vs. ≥ 75 years) and age-adjusted Charlson Comorbidity Index (aCCI < 5 vs. ≥ 5) were conducted to identify high-risk populations.
resultsThe THA group demonstrated significantly higher risks of periprosthetic fracture (OR = 2.43, 95% CI: 1.09–5.41; P = 0.030) and dislocation (OR = 4.27, 95% CI: 1.44–12.66; P = 0.009) compared to the HA, but had a reduced risk of deep vein thrombosis (DVT) (OR = 0.26, 95% CI: 0.11–0.63; P = 0.003). In high-risk subgroups (age ≥ 75 and aCCI ≥ 5), we observed dramatically increased risks of periprosthetic fracture and dislocation, but there were no differences in low-risk subgroups except for DVT. Short-term cost analysis revealed that the THA incurred higher hospitalization expenses [$13,038 ($9,047–$14,795) vs. $9,043 ($8,012–$10,178)].
conclusionTHA carries an elevated risk of mechanical complications within 3 years, especially among patients aged ≥ 75 years or with an aCCI ≥ 5. For these high-risk populations, HA should be prioritized to mitigate catastrophic risks. THA incurs higher short-term medical costs, but it may benefit low-risk patients through long-term functional improvement.
