About this trial
The goal of this clinical trial is to compare function in reverse shoulder arthroplasty (RSA) using two different degrees of humeral retroversion (RV). The main question it aims to answer is:
• Does external rotation improves when using a higher retroversion?
Participants will randomly receive a 0 degree or 30 degree RV for their RSA.
They will be followed for two years and clinical outcomes will be recorded and analyzed.

Trial outcomes
Primary outcomes

External rotation of the shoulder
External rotation of the shoulder will be measured in degrees with the help of a goniometer in two ways. First: External rotation 1 (ER1): arm adducted at zero degrees Second: External rotation 2 (ER2): arm in 90 degrees of abduction.

Constant-Murley Score
The Constant-Murley score is a multi-item functional scale assessing pain, daily activities, range of motion and strength of the affected shoulder. Its score ranges from 0 to 100 points, representing worst and best shoulder function, respectively
