Shoulder Anatomy

The shoulder is a highly movable body joint that allows various movements of the arm. It is a ball and socket joint, where the head of the humerus (upper arm bone) articulates with the socket of the scapula (shoulder blade), which is called the glenoid. The two articulating surfaces of the bones are covered with cartilage, which prevents friction between the moving bones. The cartilage is lubricated by synovial fluid. Tendons and ligaments around the shoulder joint provide strength and stability to the joint.

What is Arthritis?

When the cartilage is damaged, the two bones rub against each other causing pain, swelling and stiffness of the joint. This condition is called arthritis. There are many types of arthritis. Osteoarthritis (wear-and-tear brought about by old age) and rheumatoid arthritis (autoimmune disease) are two forms of arthritis.

What is Shoulder Joint Replacement?

Total shoulder replacement surgery is performed to relieve these symptoms. In this surgery, the damaged articulating parts of the shoulder joint are removed and replaced with artificial prostheses. Replacement of both the humeral head and the socket is called a total shoulder replacement.

Dr. Okoroha has extensive training in shoulder joint replacement and provides this service for patients in Minneapolis, St. Paul, Rochester, Eden Prairie, Minnetonka, Minnesota and beyond.

What are the Indications for Shoulder Joint Replacement?

Total shoulder joint replacement is a surgery indicated for conditions such as osteoarthritis or rheumatoid arthritis when medication, injections, physical therapy, and activity changes do not help relieve pain. Dr. Okoroha recommends surgery when you have the following symptoms:

• Severe shoulder pain that restricts daily activities
• Moderate to severe pain during rest
• Weakness and/or loss of motion

Preparation for Shoulder Joint Replacement

To decide whether total shoulder replacement is a good option for you, Dr. Okoroha will evaluate your condition thoroughly.

Dr. Okoroha reviews your medical history and performs a physical examination of your shoulder to assess the extent of mobility and pain. Imaging tests such as X-ray or MRI (magnetic resonance imaging) are ordered.

Shoulder Joint Replacement Procedure

The surgery is performed under regional or general anesthesia. An incision is made over the affected shoulder and the underlying muscles are separated to expose the shoulder joint. Dr. Okoroha may perform an open surgery, where a large incision is made, or minimally invasive, where small incisions are made to insert an arthroscope (a thin tube with a camera and light source) and surgical tools.

The upper arm bone (humerus) is separated from the glenoid socket of the shoulder bone. The arthritic or damaged humeral head is cut and the humerus bone is hollowed out and filled with cement. A metal ball with a stem is gently press-fit into the humerus.

Next, the arthritic part of the socket is prepared. The plastic glenoid component is fixed in the shoulder bone.

After the artificial components are implanted, the joint capsule is stitched, and the wound is closed.

Postoperative Care for Shoulder Joint Replacement

After the surgery, Dr. Okoroha will prescribe medications and antibiotics to control pain and prevent infection. Your arm may be secured in a sling or cast. The rehabilitation program includes physical therapy, which is started soon after the surgery and is very important to strengthen and provide mobility to the shoulder. You may be able to perform gentle daily activities two to six weeks after surgery.

Risks and Complications of Shoulder Joint Replacement

As with any major surgery, there may be potential risks involved:

• Anesthetic complications such as nausea, dizziness, and vomiting
• Infection of the wound
• Dislocation, requiring repeat surgery
• Damage to blood vessels, nerves or muscles
• Failure to relieve pain
• Pulmonary embolism
• Wear and tear of the prosthesis
