How to Know If You've Hyperextended Your Shoulder

By Michelle Zehr

A shoulder hyperextension is also known as a shoulder dislocation. When you hyperextend your shoulder, the upper arm bone -- or humerus -- has become dislocated from the ball-and-socket joint of the shoulder known as the glenoid. A fall onto an extended arm, trauma such as an auto accident or a direct collision in sports can lead to shoulder hyperextension. This condition is painful and requires immediate medical attention.
