Q

What happens in shoulder abduction that allows it to work properly?

A

During full abduction of the arm we have to laterally rotate our humerus to move the greater tuberosity out of the way

Q

scapulohumeral rhythum

A

The glenohumeral joint doesn’t account for all the movement of the humerus.
So from 0-30 degrees it is solely the glenohumeral joint
from 30-180 the scapula moves to givei ti more motion at a 2:1 Glenohumeral/scapulothoracic movement
