Outcomes of non-operatively managed Vancouver Type B1 periprosthetic femur fractures: a multi-center retrospective cohort study.
Article in BMC musculoskeletal disorders, 2025. 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
backgroundThis retrospective case series evaluated mortality outcomes in patients with Vancouver B1 periprosthetic fractures (PPFs) managed non-operatively using a matched cohort approach. We hypothesize that mortality rates will not significantly differ between operative and non-operative management of Vancouver B1 PPFs, as treatment decisions are likely driven by fracture complexity and patient comorbidities rather than a direct survival benefit of surgical intervention.
methodsThirty patients with Vancouver B1 PPFs managed non-operatively between 2011 and 2017 across five major Australian trauma centers were identified. Patients were propensity-matched to 60 operatively managed patients, matched by age, ASA score, length of stay, follow-up duration, and fracture sub-type (B1). Mortality rates at 30 days, 1 and 5 years were compared between the non-operative and operatively managed groups. For the non-operative group alone, the impact of weight-bearing status on mortality was assessed.
resultsThere was no significant difference in mortality rates between the non-operative and operative cohorts at 30-day (3.3%; 1.7%; P = 1.00), 1 year (20.0%; 3.3%; P = 0.09) and 5 years (33.3%; 30.0%; P = 0.78). For the non-operative group alone, there was no significant difference in mortality rates between WBAT and non-WBAT groups at 30 days (7.7%; 0.0%; P = 0.400), 1 year (15.4%; 17.6%; P = 0.839) and 5 years (30.8%; 35.3%; P = 0.781),
conclusionComparable 5-year mortality rates were identified between non-operatively and operatively managed Vancouver Type B1 periprosthetic femoral fractures. Despite differences in age and comorbidities, non-operative management may be a viable option for selected patients, underscoring the need for further research to refine treatment guidelines.
