External obliques, you know, the ones that are more pronounced on your lateral sides of your abdominal region, spinal flexion, lateral flexion, and then contralateral rotation.

First of all, you'll know if you have a dislocation or a fracture because it'll be one of the most painful things that you've ever experienced in your life, and these are things that need to be seen by doctors, so don't try to diagnose yourself at home using Dr. Google and try to pop things back in place, but I will say in the emergency department, before I get x-rays, if somebody thinks that there's a shoulder dislocation, I will have them take the arm that's affected and try to touch the other shoulder, so if somebody has a shoulder dislocation, they're not gonna be able to do it, so that's one of the things I do after I pop a shoulder back in place, which is awesomely satisfying I must say, we check to see if it's back in place before x-rays by seeing if that arm goes up to the contralateral shoulder that is the opposite shoulder.
