MR arthrographic analysis of labral and tendinous lesions in patients with shoulder avulsion injury.

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
objectivesThis study aimed to evaluate the frequency and characteristics of specific labral lesions (SLAP and Bankart) and associated tendinous injuries in patients with avulsion fractures of the shoulder using magnetic resonance (MR) arthrography and to investigate their potential clinical implications.
methodsA retrospective review was performed on 850 shoulder MR arthrograms retrieved from our institutional PACS database.The study comprised a total of 35 patients with confirmed avulsion fractures and 30 age- and sex-matched controls. . All patients received both conventional MR imaging and 3D volumetric MR arthrography sequences. The evaluation focused on labral lesions (SLAP, Bankart), rotator cuff injuries and biceps tendon pathology which were systematically evaluated by two experienced radiologists.
resultsThe avulsion fracture of the greater tuberosity was the most commonly observed, accounting for 60% of cases. Labral pathology was considerably more prevalent among the patient cohort (51.4%) compared to the control group (23.3%) (p=0.039). Superior labrum anterior to posterior (SLAP) lesions were the most frequently identified labral abnormalities, and were significantly more common than both Bankart lesions (17.1%) and Bankart variant lesions (2.9%) (p=0.015). Patients presenting with fractures of the lesser tuberosity demonstrated a notably higher incidence of combined rotator cuff and biceps tendon pathology (77.8%) in contrast to those with greater tuberosity fractures (14.3%) (p=0.002).
conclusionsThe research underscores a robust link between avulsion fractures and superior labral injuries, especially SLAP lesions. Moreover, there was a significant correlation between lesser tuberosity fractures and extensive tendinous pathology, indicating a greater degree of biomechanical compromise. These results highlight the critical role of MR arthrography in identifying concurrent labral and tendinous injuries that could affect clinical decision-making.
