Does the position of the scapula in relation to the glenopolar angle change the preferred treatment of extra-articular fractures?

As the rotation of the scapula was displaced from the scapula in the coronal position (GPA 0°), both in internal rotation and in external rotation, the GPA reduced. Therefore, rotational displacement may lead to an error in GPA measurement, resulting in incorrect indication of treatment. It is recommended that whenever possible, GPA measurements should be taken in neutral rotation, with the scapula in a neutral position at 0°.
