Comparative Outcomes of Dual Mobility Cup versus Bipolar Hemiarthroplasty in Patients with Neurological Disorder with Femoral Neck Fractures.

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
Purpose: To compare the risk of periprosthetic and medical complications following dual mobility cup total hip arthroplasty (DMC-THA) and bipolar hemiarthroplasty (BHA) for femoral neck fractures in patients with neurological disorders. Materials and Methods: This retrospective study included patients with neurological disorders who underwent DMC-THA (n=1,153) or BHA (n=4,612) between 2016 and 2022, identified from the Korean Health Insurance Review and Assessment Service database. Propensity score matching was performed at a 1:4 ratio to adjust for baseline characteristics. The primary outcome was periprosthetic complications; the secondary outcome was medical complications. Results: Compared with the BHA-matched group, the DMC-THA group showed a higher rate of early periprosthetic fracture (2.6% vs. 1.4%, Conclusion: DMC-THA was not superior to BHA in preventing dislocation and was associated with a higher risk of periprosthetic fracture and late dislocation in neurologically impaired patients. Surgeons should recognize the risks of using DMC-THA implants as a sole strategy to prevent instability in this high-risk population.
