Dr. Derek Papp, Sports Medicine Physician with Miami Orthopedics and Sports Medicine Institute, explains the shoulder is like a golf ball that sits on a tee and in the shoulder dislocation the ball slips off of the tee.
He also says shoulder separation is similar and it is when you dislocate the AC joint (acromioclavicular joint). He points out these injuries are caused when the arm is brought out and it pops the ball forward and out.
