Study summary

This study evaluates the reliability of CT-based assessment of acromial morphology and its relationship with age, in order to improve understanding of shoulder pathologies such as subacromial impingement and rotator cuff tears.

Inclusion Criteria: * Subjects aged 20 to 89 years * Shoulder CT or arthro-CT performed at Strasbourg University Hospitals * Examination performed between 02/01/2009 and 11/12/2023 * Independent indication for imaging * No documented opposition to reuse of medical data for research Exclusion Criteria: * Imaging not performed * Poor image quality * Inability to perform 3D reconstruction * Duplicate examination within the same age group * History of acromial fracture * Previous surgery interfering with acromial analysis (arthroplasty, acromioplasty, osteosynthesis, arthrodesis) * Shoulder pathology interfering with acromial analysis (severe acromioclavicular arthropathy, humeral head osteonecrosis, glenohumeral dysplasia)

Primary outcome measure(s)

  • Intra-Rater and Inter-Rater Reliability of the Bigliani Classification of Acromial Morphology — Initial assessment, with repeat assessments at 3 and 6 months after the initial assessment.
    Acromial morphology will be classified as Type I (flat), Type II (curved), or Type III (hooked) according to the Bigliani classification, using 3D-reconstructed shoulder CT scans or CT arthrography images. Intra-rater and inter-rater reliability will be assessed using kappa agreement coefficients (Cohen's kappa and Fleiss' kappa). Five evaluators will assess the images, with repeat evaluations at 3 and 6 months after the initial assessment.
