AC Joint Sprain

An Overview of an AC Joint Sprain

An AC joint sprain is a fairly common shoulder injury among active individuals. A shoulder sprain in the AC joint is typically caused by a direct blow to the “point” of the shoulder or a fall onto the shoulder joint. An AC joint sprain is characterized by the tearing of the connective tissue and ligaments of the acromioclavicular (AC) joint. Dr. Peter Millett, serving patients from Vail, Aspen and the surrounding Denver, Colorado communities, specializes in diagnosing and treating shoulder pain associated with a shoulder sprain in the AC joint.

The AC joint is responsible for connecting the shoulder blade to the clavicle. The joint allows for a small range of shoulder movement compared to the shoulder joint. When the AC joint is put under extreme stress during sports or work activity, it has the potential to tear. When a tear occurs, it is known as an AC joint sprain. A shoulder sprain in the AC joint can range from a small sprain, causing minimal shoulder pain, to a severe sprain causing extreme pain, instability and deformity.

What are the Symptoms of an AC Joint Sprain?

Many individuals who sustain an AC joint sprain will experience a sudden onset of shoulder pain located at the top of the shoulder joint. The pain may increase during certain activities such as overhead lifting, pushing and pulling movements and when moving the arm across the body. In a minor AC shoulder sprain, an individual may be able to perform daily activities with limited pain, swelling and stiffness. In more severe cases, a deformity may be visible from the tearing of the connective tissue holding the AC joint together.

Have you sustained an AC joint sprain?

There are two ways to initiate a consultation with Dr. Millett:

You can provide current X-rays and/or MRIs for a clinical case review ($250).

You can schedule an office consultation with Dr. Millett.

How is an AC Joint Sprain Diagnosed?

In order to diagnosis a shoulder sprain of the AC joint, Dr. Millett will perform a thorough physical examination. He will ask questions regarding the patient’s medical history as well as what led to the injury. Dr. Millett will also move the affected shoulder to determine areas of shoulder pain and weakness. X-rays and an MRI may also be performed to determine the extent of the AC joint sprain and to rule out any other possible shoulder injuries.

How is an AC Joint Sprain Treated?

Active individuals can recover from an AC shoulder sprain in a few weeks without the need of surgical intervention. Dr. Millett typically begins with conservative treatment options to alleviate shoulder pain such as rest, activity modifications, shoulder immobilization, ice and a physical therapy program.

Dr. Millett may recommend surgical treatment if conservative treatments do not alleviate the symptoms. Surgery may also be recommended for athletes and workers that require a full recovery to perform necessary, everyday movements. There are numerous procedures designed to treat an AC joint sprain, including arthroscopic shoulder surgery for AC repair. Dr. Millett will explain the different treatment options to his patients and will suggest the best course of action.

Dr. Millett and his team did a SLAP tear repair and bicep tenodesis on my left shoulder. I use my arms as an artist, and love to swim in the ocean, surf, paddle, and telemark ski. So regaining full use of my shoulder and keeping my bicep attached was very important to me. Now, over two years later, my shoulder has the equivalent range of motion as my other arm and as before the injury, and no pain. After the first three months it felt so good and was so strong that - to my horror - I completely forgot my six-month follow-up.

Not only did Dr. Millett and his team make my arm as good as new, but having had the experience of such kindness and expertise throughout the process of surgery and recovery is like an added shoulder superpower.

Thank you Rita, Brooke, Jason, Sarah, Camille, Olivia, Dr. Millett and everyone! And see you soon when my husband comes in for his knee...

Flawless procedure, Easy recovery

Dr. Millet's repaired my knee and tibia, following a botched operation by a different surgeon. That procedure was virtually pain free and I was weight bearing within a few days. That was 18 years ago and the knee is still strong. A few years after the knee incident, Dr Millet repaired my shoulder. My insurance company approved me for 3 months of disability following that surgery. I was off pain medication in 2 days and had 90% range of motion within a week. I withdrew my disability claim and returned to work within two weeks of surgery. I’m not a famous athlete—just a regular guy. Nonetheless, I was treated like an NFL at the Steadman clinic. Most notable was the time for recovery. Other surgeons perform their hour-long task in the OR and don’t involve themselves in the other functions. Peter and his team manages the entire process from diagnosis, anesthesia, nursing care, and therapy. He takes a holistic approach to patient care and doesn’t skip any steps.

Saved My Life

I went to Dr. Millett after 7 knee surgeries (6 on my right and 1 on my left) and had seen 11 different surgeons who all refused to remove femur metal from my right leg. I am highly allergic to metal and the chronic pain was leaving me bedridden for 3.5wks out of a month. He personally wrote me back on my inquiry, listened to my concerns, scheduled my surgery within a week (due to insurance issues) and personally followed up with my recovery. The level of patient care from Dr. Millett and his ENTIRE team is above any care I have ever received in my 20 years of dealing with orthopedic surgeons. There are not enough words to describe the level of care, dedication and professionalism you receive from Dr. Millett and his staff.
My only disappointment is that I did not find him sooner!!!
