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.

Conditions

Shoulder Injuries; Rotator Cuff Tears; Rotator Cuff Injuries

Outcome Measures

Primary Outcomes (2)

• Critical Shoulder Angle

  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.

  2 hours

• Acromial Index

  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.

Interventions

Computed Tomography OTHER

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

Control group; The rotator cuff tear group

Eligibility Criteria

• Age: 17 Years - 80 Years
• Sex: all
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

In this study, computed tomography examinations of patients who applied to Gazi University Faculty of Medicine Department of Orthopedics and Traumatology between 2016-2019 were examined retrospectively.

You may qualify if:

• 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.

You may not qualify if:

• Those with an inflammatory disease and trauma history were not included in the study.
