The shoulder has the largest range of motion of any joint in the body. Everything from scratching your back to lifting a book requires your shoulder. Because of this, the shoulder is often subject to overuse, traumatic injury, and/or natural body changes, leading to pain and tissue damage.

How Your Shoulder Works
Shoulder bones are:
• The shoulder blade (scapula);
• The collarbone (clavicle); and
• The upper arm bone (humerus).
The shoulder blade and the collarbone come together on top of the shoulder to form the acromioclavicular (AC) joint.
The upper arm bone is shaped like a ball to fit neatly into a socket on the shoulder blade. This is called the glenohumeral joint. The socket is shallow to allow a wide range of arm motion. Inside the socket is a flexible rim of soft tissue called the labrum, which helps increase the stability of the shoulder.
Four muscles surround the shoulder joint to help to rotate the arm and provide additional stability. Together, these muscles form the rotator cuff.
Many other muscles help move the shoulder, such as the pectoralis muscles (pecs) on the chest or the latissimus dorsi (lats) on the back.
In order for the shoulder to function properly, the bones, joints and muscles must work in unison.
Evaluating Shoulder Pain
Evaluation for shoulder pain starts telling us when and how it started, how it feels, and which treatments you have tried. We’ll also review your health history looking for other medical conditions that may be causing or contributing to your pain.
We do a physical exam to test your shoulder structures and check your shoulder’s range of motion and strength, and do tests to uncover specific problems.
Sometimes we order X-rays or MRIs to visualize bones and soft tissues. X-rays can show fractures, spurs, and changes from arthritis. MRIs can show more bone detail, as well as soft-tissue damage like rotator-cuff or labrum tears.
In some cases, we need input from other specialists, particularly neurologists, who can evaluate and test the nerve supply to the shoulder.
Whatever the cause of your shoulder pain, we are dedicated to helping you find the best treatment. Request an appointment today.
