Acromial Shape and Age: How CT Looks at Shoulder Bone Shape

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This retrospective, single-center study analyzes 420 patients who had shoulder CT or arthro-CT at Strasbourg University Hospitals between 2009 and 2023. Acromial morphology is classified using the Bigliani system on 3D reconstructions, and the researchers assess how consistently different observers score the images (intra- and inter-observer reliability). They also explore whether acromial shape changes with age. Data come from medical records and imaging software, with repeat assessments at 3 and 6 months to gauge reproducibility. The study aims to clarify how acromial morphology relates to shoulder problems like impingement and rotator cuff tears, using existing imaging data.
