Shoulder Anatomy

Shoulder  joints allow us to bend, flex, reach, and rotate our arms. However, repetitive overhead movements that are common to some sports and jobs frequently overstress the shoulder joints resulting in injury. When problems related to tendon tears, in stability, fractures, arthritis and other conditions impede movement, both surgical and non-surgical treatments are considered to ease pain and help restore movement.shoulder_anatomy

The shoulder is a ball and socket joint. The ball is called the head of the humerus and the socket is called the glenoid (it’s part of your shoulder blade, also known as the scapula). Sometimes, arthritis can form here. On top of this ball and socket joint is another bone known as the acromion. This is a frequent place for bone spurs to form. Right next door to the acromion is the acromioclavicular joint or “AC joint” for short. This is the location where shoulder separation occurs.

A group of 4 deep muscles helps to move your shoulder joint; they are called the rotator cuff. These muscles work together to help get your arm up over your head, as well as rotate it in and out. That’s why rotator cuff injuries usually result in weakness, especially in trying to raise the arm overhead. One of the 4 muscles is injured much more frequently than the others; it is known as the supraspinatus muscle.

In addition, these rotator cuff muscles function to help keep your shoulder “in socket”, or “located” (when the shoulder comes out of socket, it’s called “dis-located”). You have several ligaments in your shoulder that help to keep it in place. Finally, there’s an “O-ring” around the socket, called the labrum, which also helps keep your shoulder in socket and causes pain and popping when it’s torn.
