Anatomy of the shoulder
The shoulder is a unique and complex joint. The shoulder needs a high degree of flexibility, but it also needs to remain stable in multiple planes of motion. To accomplish this, the shoulder joint is supported by a combination of bones, ligaments, and muscles.
The shoulder is made up of the following parts:
- Acromioclavicular (AC) joint – where the collarbone (clavicle) meets the top of the shoulder (acromion).
- Glenohumeral joint – where the head of the upper arm bone. (humerus) and the shoulder socket (glenoid fossa of the scapula) meet.
- Labrum – a cartilage ring around the shoulder socket that makes the socket deeper and more stable for the humeral head to sit in. A joint capsule surrounds these structures.
- Rotator cuff tendons – tendons that attach the four rotator cuff muscles to the humerus to both maintain stability and move the shoulder in all directions.

How are shoulder injuries diagnosed?
The diagnostic process starts by talking with you about your symptoms and conducting a detailed physical examination. Diagnostic imaging, including X-rays and MRI scans, can be useful for a diagnosis as well.
What are the treatment options for shoulder injuries?
Some symptoms can be relieved by avoiding activities that make your symptoms worse.
Over-the-counter medications such as Aleve, Advil, Motrin, and aspirin can help reduce swelling and pain.
Place a bag of ice directly onto the shoulder for 20 minutes to reduce and prevent inflammation.
In the specialist’s office, medication is injected directly into the joint. Injections can provide lasting relief of pain and swelling.
A therapist can work with you to improve strength and to teach proper shoulder mechanics.
