Brief Summary

This retrospective study is to investigate the influence of the Greater Tuberosity Angle (GTA) in addition to CSA on patient outcome in patients with rotator cuff tear.

Conditions

Rotator Cuff Tear

Keywords

Critical Shoulder Angle (CSA); Greater Tuberosity Angle (GTA)

Outcome Measures

Primary Outcomes (1)

• Change in Constant Score

  This scoring system consists of four variables that are used to assess the function of the shoulder. The right and left shoulders are assessed separately. The subjective variables are pain and activity of daily life (ADL) (sleep, work, recreation / sport) which give a total of 35 points. The objective variables are range of motion and strength which give a total of 65 Points (the higher the score the better the shoulder function).

Other: data analysis

Interventions

data analysis OTHER

Data is extracted from the existing medical records and from the Rotator Cuff Repair Database (RCR\_USB). The GTA (determined as the angle between a "line parallel to the humerus diaphysis passing through 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") is determined.
