[Periprosthetic glenoid and acromial fractures after primary shoulder arthroplasty : Diagnosis, treatment, and revision strategies].
Review in Unfallchirurgie (Heidelberg, Germany), 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
backgroundPeriprosthetic fractures of the glenoid and acromion are rare but clinically relevant complications following primary shoulder arthroplasty. Due to the increasing use of reverse shoulder arthroplasty, the incidence of these fractures is expected to increase.
objectiveThis review aims to summarize current evidence on the pathomechanisms, diagnosis, treatment strategies, and prognostic factors of periprosthetic glenoid and acromial fractures from a trauma and orthopedic surgery perspective. MATERIALS AND
methodsA narrative review of current clinical and biomechanical literature addressing periprosthetic fractures of the glenoid, acromion, and scapular spine was conducted.
resultsPeriprosthetic glenoid fractures are challenging due to limited bone stock and their close relationship to implant stability. Key decision parameters include component stability, fracture morphology, and remaining bone stock. Computed tomography is essential for diagnosis and surgical planning. Acromial and scapular spine fractures mainly occur after reverse shoulder arthroplasty, which nowadays constitutes a significant proportion of implantations; they are typically insufficiency fractures and are associated with limited functional outcomes. Conservative treatment is recommended in most cases.
conclusionA differentiated evaluation of periprosthetic glenoid and acromial fractures, taking into account their specific pathomechanisms, biomechanical conditions, and prognostic implications, is essential for appropriate therapeutic decision-making.
