Shoulder Replacement Surgery

How Does Your
Shoulder Work?

The shoulder is comprised of three main bones: the collarbone (clavicle), the shoulder blade (scapula) and the upper arm bone (humerus). The glenoid (part of the scapula) and humeral head (part of the humerus) are normally the parts of the shoulder that have to be replaced because they rub together when you move your arm.

In a healthy shoulder, these portions of bone are covered with cartilage, which allows for painless motion—lifting, pushing and pulling. But arthritis can damage this protective cartilage, which makes these motions painful.

Arthritis is one of the most common conditions that causes wear and tear to your joint cartilage and develops after years of constant motion and pressure on the joints. If non-surgical treatment options such as medication, physical therapy or lifestyle changes fail to provide relief, your surgeon may recommend shoulder replacement surgery.

What is Shoulder Replacement Surgery?

During a total shoulder replacement surgery, a doctor takes out the damaged parts of your shoulder joint and replaces them with new parts.

Your surgeon will:

  • Put you under anesthesia.
  • Make a cut so they can access your shoulder joint.
  • Remove the damaged parts of your bones or cartilage.
  • Replace the removed parts with metal and plastic implants.

Shoulder Replacement Options

A primary, or anatomic, shoulder replacement is one type of surgery your doctor may want to do.

During primary shoulder replacement surgery, your surgeon will:

  1. Make a cut in the front of the shoulder so they can access your joint.
  2. Take out the damaged bone and cartilage.
  3. Remove the head of the bone at the top of your arm.
  4. Place a metal stem into your arm bone.
  5. Place a plastic socket implant on your shoulder blade.

If you have damage to your rotator cuff muscle, your surgeon may want to do a reverse total shoulder replacement surgery.

During reverse total shoulder replacement surgery, your surgeon will:

  1. Make a cut in the front of the shoulder, so they can access your joint.
  2. Take out the damaged bone and cartilage.
  3.  Remove the head of the bone at the top of your arm.
  4. Attach a metal ball to the shoulder blade.
  5. Place a metal implant into the upper arm bone.
  6. Attach a plastic socket to the implant in the upper arm bone.

Can Shoulder Replacement Technology Help Me?

To get the best results for your shoulder replacement surgery, your surgeon must understand your unique bone shape before the surgery so they can put each new shoulder part in the right place.

If they do not, then your new shoulder parts may not work the way they should.

For many years, surgeons have used X-rays, surgical tools, and special techniques to plan surgeries. But now, advanced technologies for shoulder replacement are available to help your surgeon get your shoulder implant positioned just right.

You may have heard of robotics, robot-assisted surgery or computer-assisted surgery. Exactech Active Intelligence surgeons use a computer-assisted shoulder surgery technology. It is called ExactechGPS Guided Personalized Surgery. ExactechGPS helps surgeons plan for your surgery using a virtual simulation on a computer.

How ExactechGPS Shoulder Replacement Technology Works

Prior to surgery, Active Intelligence surgeons use your CT scan to create a 3D model on a computer to clearly see your shoulder joint and bone structure. This helps the surgeon decide where to make bone cuts and place your implant. Personalized just for you, your surgeon can plan your surgery through a virtual simulation before even entering the operating room. Then, during surgery, your doctor will use this plan to place your shoulder implant just where it should be.1

These are some of the features of ExactechGPS:

Trackers

With a few simple trackers placed on the patient’s bone, the system sends data on the patient’s anatomical structure and joint movement to the computer.

Screen

The images on the screen allow the surgeon to verify where to remove bone and appropriately place the implant.

Measurements

The computer analyzes the information it has gathered and displays it on the screen in a graphical format with calculated key measurements.

With any surgery, there are potential risks, and results will vary depending on the patient. Joint replacement surgery is not for everyone. Check with your physician to determine if you are a candidate for joint replacement surgery. Your physician will consider the risks and benefits associated with this procedure, as well as individual factors such as the cause of your condition, your age, height, weight and activity level.
