Morphological characteristics of the acromion and the coracoid process in the scapula analyzed by 3D-CT: relationship to rotator cuff tear

We compared the morphologies of the acromion and the coracoid process in the scapula between rotator cuff tear (RCT) and control groups. The subjects consisted of 36 patients who underwent arthroscopic rotator cuff repair in our hospital, and 39 undergoing whole-body CT examination in the trauma center who had neither fractures nor osteoarthritis changes in the scapulohumeral joint on CT images. Using 3D-CT, critical shoulder angle (CSA) and acromion overlap (Ao) —defined by the length from the glenoid to the lateral edge of the acromion divided by the width of the scapula body—were measured.
