Clavicle fractures and high-grade acromioclavicular joint injuries do not affect posture and thoracic kyphosis in young adults: A prospective comparative study.

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: Clavicle fractures and high-grade acromioclavicular joint injuries are frequently associated with altered shoulder-girdle function, but their impact on spinal posture remains unclear. This study aimed to evaluate whether these periclavicular injuries are associated with clinically relevant alterations in thoracic or cervical spinal alignment that would justify targeted spinal assessment or intervention. Methods: In this prospective comparative study, 45 patients with periclavicular injuries and 52 age-matched healthy controls were assessed using rasterstereography to quantify spinal alignment in the sagittal (cervical plumb line distance, kyphosis and trunk inclination angles) and coronal planes (lateral deviation and plumbline deviation). The primary outcome was thoracic kyphosis angle. Subgroup analyses were performed based on injury chronicity (acute vs. subacute) and side dominance. Results: No significant differences in thoracic kyphosis or coronal/sagittal spinal parameters were observed between patients and controls, leading to rejection of the study hypothesis. Injury chronicity and side dominance did not influence outcomes. Conclusions: Periclavicular injuries are not associated with increased thoracic kyphosis on static posture assessment. These findings suggest that routine concern for structural thoracic kyphosis after clavicle fractures or high-grade acromioclavicular joint injuries may be unwarranted in the context of static assessment. Level of Evidence: Level II, prospective comparative study.
