Critical Shoulder Angle and Acromial Index on 3D Models
Study Details
Study Description
Brief Summary
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.

Outcome Measures
Primary Outcome Measures
- Critical Shoulder Angle [2 hours]
The critical shoulder angle is defined as the angle formed between the plane of the glenoid and the line connecting the most lateral border of the acromion process, as seen on the true anteroposterior radiograph of the shoulder.
- Acromial Index [2 hours]
The acromial index is the distance between the glenoid plane and the lateral border of the acromion divided by the distance between the glenoid plane and the lateral aspect of the humeral head.
Eligibility Criteria
Criteria
Inclusion Criteria:
- A total of 44 patients, including 24 patients with proven rotator cuff tear by arthroscopic surgery (rotator cuff tear group) and 20 patients with proven Bankart lesion and no rotator cuff tear by arthroscopic surgery (control group), were included in the study.
Exclusion Criteria:
- Those with an inflammatory disease and trauma history were not included in the study.
