Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Objective: The relationship between rotator cuff tears and morphological features of the shoulder joint has not been fully explained. The earlier studies are usually done with two-dimensional radiography images, but joint positions and bone formations could not be fully evaluated in two-dimensional images. This study aims to evaluate the relationship between rotator cuff tears and critical shoulder angle (CSA) and acromial index (AI) values in three dimensions.

Methods: This study examined computerized tomography of 24 rotator cuff tears (rotator cuff tear group) and 20 Bankart lesions, and no rotator cuff tears (control group). CSA and AI were measured on three-dimensional glenohumeral joint models obtained by three-dimensional reconstructions of computed tomography examinations.

The investigators anticipate results of this study will guide clinicians in revealing the etiology of rotator cuff degeneration and determining the surgical method to be used for treatment.
