Abstract

The purpose was to evaluate the relationship between GTA, CSA, and the delamination patterns of RCTs. This study included 315 patients with RCTs from 2014 to 2018, retrospectively. The subjects were divided into 5 groups: Group A, control group; Group B, non-delaminated tear; Group C, delaminated tear with equally retraction of articular and bursal layer; Group D, articular layer more retracted delaminated tear, and Group E, bursal layer more retracted delaminated tear. In conclusion, large GTA and CSA were associated with rotator cuff tears. However, there was no difference of GTA and CSA according to the delamination patterns.

Keywords: Case series; Critical shoulder angle; Delaminated; Delamination; Level IV; Rotator cuff; greater tuberosity.

The angles between a line connecting the superior and inferior osseous margins of the glenoid cavity and a line connecting the inferior osseous margins of the glenoid cavity and the inferolateral border of the acromion were measured as the critical shoulder angle.

The angles between a line that parallel line to the diaphyseal axis passing though the humeral head center of rotation and a line connecting the upper border of the humeral head to the most superolateral edge of the greater tuberosity were measured as the greater tuberosity angle.
