Acromioclavicular (AC) joint injuries are more commonly known as a separated shoulder. The AC joint is where the shoulder blade meets the collarbone. It functions as a pivot point allowing you to raise your arm above your head. Patients active in sports such as football, soccer, snowboarding, skateboarding, and other physically demanding activities are typically at the highest risk of this injury. If you have lost full range of motion, or have been experiencing pain as a result of a separated shoulder, our doctors in Austin, TX, can diagnose and treat your pain. To set up your consultation, please contact us today.
If an Injured shoulder is keeping you out of the big game, or away from work, we can provide the proper treatment needed to help you restore your full range of motion.


There are many causes of AC injuries, but they most typically occur when patients fall directly onto the top of their shoulder, or onto an outstretched arm. The fall can cause ligaments attached to the underside of the clavicle to tear and separate from the collarbone and wingbone. Depending on the severity of the injury, pain levels can range from mild to severe.

There are six types of AC injuries, ranging from minor separations and pulls to full dislocations and ligament ruptures. To measure severity, the injury is graded using the Rockwood scale. This scale ranges from Grade I through Grade VI, increasing in severity with each increment. Typically, most AC injuries are between Grade I and Grade III.
Injuries with Grades IV to VI are commonly associated with extreme an incident such as a motor vehicle accident.

The most common type of AC joint injury is a slight displacement of the joint. The AC ligament may be stretched or partially torn. Patients may experience mild tenderness when the joint is touched, and minor pain with arm movement.
The joint has become partially dislocated, and the AC ligament is completely torn. Pain in the joint is moderate to severe at this level. A small bump on the top of the shoulder may also be visible as the collarbone is no longer properly secured in place
A complete displacement is evident, as the shoulder falls under the weight of the arm. This forces the clavicle higher, causing a noticeable bump or deformity on the shoulder. Additionally, the AC ligament, coracoclavicular (CC) ligament, and the capsule that surrounds the joint are all torn. Pain is felt upon any arm movement, and is also experienced around the joint and in the area of the CC ligaments.
During your initial evaluation, we will gently examine your shoulder to assess the bones and tissues around the injured area. We will look for a small bump or tenderness that may suggest a separation of the joint. If we are unable to determine whether a separation has occurred, we may use x-rays to make a proper diagnosis.

Depending on the severity of the injury, most patients with Grade I through Grade III injuries can be treated without surgical intervention. If your injury is minor, treatments may include icing, a protective sling, and pain and anti-inflammatory medications. You may also participate in a rehabilitation program to strengthen the shoulder and restore range of motion. The majority of patients will be pain-free and experience full range of motion within two to three months.

If you have not achieved full range of motion, and continue to experience pain after three months of non-operative treatments, you may be required to undergo a surgical procedure. Surgery can help stabilize the separated AC joint, and lessen the visible deformity of your shoulder. A surgical procedure can also be performed to correct persistent AC joint injuries from years prior.


Like most any surgery, joint replacement also has the potential of causing nerve damage. If nerve damage has occurred, you will notice a lack of sensation in areas near the surgical site. While this side effect can be an annoyance, it is not considered an emergency.
Your wound may be infected if you notice an increase in redness, tenderness, swelling, pain, and drainage from the procedure area. You will need to contact your doctor right away so they can assess your joint and determine if another surgery to remove the replacement is needed for the infection to heal.
You may have a blood clot if you are noticing throbbing pain, increased inflammation, increased redness, and increased warmth. The symptoms can be similar to those of an infection, so this needs to be treated by your doctor right away. Quick treatment is crucial because blood clots can lead to severe complications, and can be fatal in some cases.
Although rare, a loosening or dislocated prosthesis is a potential side effect that needs to be immediately treated by your doctor. Contact Dr. Heinrich or Dr. Dodgin if you are experiencing any feeling of instability, increased swelling, or increased pain, as these might be a sign of an issue with your prosthetic.
Temporary pain, swelling, and bruising are normal after surgery, and should subside within a few weeks to months. However, all surgeries involve risks that patients should understand before deciding to undergo treatment. You can minimize these risks by choosing a qualified and reputable surgeon and following their instructions as carefully as you can during recovery.
Often, any patient who has tried all other non-invasive treatments and has seen no results is a good candidate for joint replacement. However, some factors can affect your candidacy:

Total joint replacement is usually recommended for people between the ages of 55 and 80.

Any underlying medical conditions need to be addressed with your surgeon before your procedure. Your candidacy will depend on the type and severity of your underlying disease.

Severely overweight or obese patients may not be good candidates for a joint replacement. The excess weight adds stress to the artificial joint and can sometimes lead to its failure.

It will be recommended that you stop smoking before and after your joint replacement. Studies have shown there is a higher risk of medical complications and a need for a joint revision in patients who smoke.

Dr. Seade did an excellent job on my torn rotator cuff repair! He also had to remove a bone spur and reattach my bicep muscle! My recovery has went very well and after 12 weeks I finally get to start strength training on my left shoulder and arm! I will be back barrel racing in no time!
