Shoulder Arthritis

Your shoulder is made up of three bones: your humerus (upper arm bone), your scapula (shoulder blade), and your clavicle (collarbone). The top of the humerus fits into the socket, called the glenoid. The muscles and tendons that keep your arm centered in your socket are called the rotator cuff. There are two joints in the shoulder: the acromioclavicular (AC) joint, where the clavicle meets the tip of the shoulder blade (acromion). The second is the glenohumeral joint, where the top of your humerus fits into the scapula. Arthritis can affect either or both of these joints. There are five types of arthritis that commonly affect the shoulder. Osteoarthritis is generally known as the “wear and tear” arthritis. Rheumatoid Arthritis is an autoimmune disease, where the immune system attacks the joints in the shoulder. Posttraumatic arthritis is a form of osteoarthritis that originates from an injury. Rotator Cuff Tear Arthropathy develops after a long-standing rotator cuff tendon tear. Because the rotator cuff is torn it cannot hold the head of the humerus in the glenoid socket, which causes it to move up and rub against the acromion. Avascular Necrosis occurs when the blood supply to the head of the humerus is disrupted, causing the bone cells to die without blood, eventually leading to the destruction of the shoulder joint.


  • Weakness
  • Stiffness
  • Pain aggravated by activity
  • Limited range of motion
  • Pain at night causing difficulty sleeping on the affected side
  • If the glenohumeral joint is affected, the pain will resonate from the back of the shoulder and may intensify with weather changes
  • If the acromioclavicular joint is affected, the pain will resonate from the top of the shoulder and can radiate to the side of the neck

Nonsurgical Treatment

    In order to reduce pain and increase mobility and function, we offer several different nonsurgical treatments to alleviate your symptoms. Weight loss, exercise, and medication can greatly reduce pain. Shoulder injuries may require rest or a change in the way you move your arm to do things. Physical therapy may improve your range of motion. Hot and cold packs, as well as taking a bath can help. Cold lessens inflammation while heat boosts circulation.

Surgical Treatment

    As a last resort, surgery is an option. Speak with Dr. Osmani to discuss your surgical options.
