Outcomes of nonoperative treatment of displaced anterior glenoid rim fractures without dislocation in the elderly: should instability be a concern?
Article in BMC musculoskeletal disorders, 2025. 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
purposeThe management of displaced anterior glenoid rim fractures remains a topic of debate, particularly in elderly patients where surgical risks are heightened. While surgical intervention is often recommended to prevent instability and degenerative arthritis, some studies suggest that nonoperative treatment may yield satisfactory results. This study aims to evaluate whether nonoperative treatment of displaced anterior glenoid rim fractures leads to anterior shoulder instability in elderly patients.
methodsA retrospective review was conducted on patients over 60 years of age diagnosed with Ideberg type Ia anterior glenoid rim fractures (> 5 mm fragment) who underwent nonoperative treatment. Patients with associated injuries, neurological disorders, or dislocated fractures requiring reduction were excluded. Treatment involved sling immobilization for up to 4 weeks, followed by a structured rehabilitation program. Clinical outcomes were assessed using Constant Score (CS), American Shoulder and Elbow Surgeons (ASES) score, Subjective Shoulder Value (SSV), and range of motion. Radiographic evaluation included fracture healing, displacement, and osteoarthritis progression. Statistical analyses were performed using the Wilcoxon signed-rank test and Fisher exact test.
resultsA total of 21 patients (mean age: 69 years, mean follow-up: 82 months) were included. No cases of subsequent instability (dislocation or subluxation) were observed. At final follow-up, 71% of fractures showed complete healing, while 28% exhibited partial healing with a ≤ 5 mm step. Functional outcomes were favorable, with mean CS of 86, ASES of 87, and SSV of 89%. External rotation in abduction was slightly limited compared to the contralateral side (p = 0.0026). Radiographic signs of new-onset osteoarthritis were present in 4 patients, but none reported instability-related symptoms.
conclusionNonoperative treatment of displaced anterior glenoid rim fractures without dislocation in elderly patients provides satisfactory functional and radiographic outcomes, with no evidence of subsequent instability. This approach effectively avoids surgical risks and complications while preserving shoulder function, supporting its role as a viable treatment strategy in this population.
