Shoulder Anatomy

The shoulder joint is the most flexible joint in the entire human body. One of the most complex joints, the shoulder joint, is also one of the largest. It is made up of three bones: the scapula (shoulder blade), clavicle (collar bone), and humerus (arm bone.) Three smaller joints move together to make up the large shoulder joint and to provide a large range of motion, those include: the acromioclavicular joint, the sternoclavicular joint, and the glenohumeral joint. The glenohumeral joint has also been called the ball and socket joint of the shoulder. If the shoulder stops functioning, or is causing pain with normal activity, The Shoulder Clinic of Idaho, serving Boise, Meridian, Nampa, and the surrounding communities of the Treasure Valley can help diagnose and treat conditions of the shoulder.

What are the important structures in the shoulder joint?

The anatomy of the shoulder joint includes structures that help the joint to move. Shoulder stability is a key element of a properly functioning shoulder joint and is achieved with the help of cartilage, ligaments, tendons and muscles, all working together to connect, cushion and rotate the shoulder joint.

Other important structures of the shoulder anatomy include:

Labrum – The labrum keeps the ball of the humeral head (arm bone) in place and helps prevent dislocation. It is a piece of rubber-like cartilage that is attached to the rim of the shoulder socket.

Bursa – A small, fluid-filled sac, located between the bone and surrounding soft tissue, lubricates and cushions the rotator cuff tendon.

Rotator Cuff – The rotator cuff is a group of muscles and tendons that surround the shoulder joint. The rotator cuff holds the head of the humerus firmly within the shallow socket of the shoulder.  The rotator cuff muscles and tendons contribute to shoulder stability and shoulder strength.

The shoulder is a complex joint which makes work and play possible. However, this wide range of motion can come at a cost and shoulder injuries can be common. Any shoulder injury or problem should be evaluated by the shoulder specialists at The Shoulder Clinic of Idaho.
