AC Separation Treatment

AC Separation Treatment Overview

The collarbone (clavicle) attaches to the roof of the shoulder (acromion) in a joint known as the acromioclavicular (AC) joint. This area of the shoulder is easily defined because it is the bump that you can feel on the top of the shoulder. The collarbone is also stabilized in this area by ligaments called the coracoclavicular ligaments. These ligaments attach the collarbone to the front of the shoulder blade (scapula). Direct trauma to this shoulder area from a fall or a direct hit during sports activities can damage the connections and lead to an injury where the collarbone and roof of the shoulder are no longer sitting next to each other. This is often referred to as an AC separation and leads to elevation of the collarbone that can be felt at the top of the shoulder. When an AC separation is not healing with conservative treatment options, a surgical AC separation treatment may be recommended by Dr. Peter Millett.

An AC separation occurs when the clavicle and acromion are no longer aligned correctly. In mild AC separations, the injury may be treated by conservative measures such as rest, sling use and a short physical therapy rehabilitation program. If there is continued pain and limited function of the AC joint because the AC separation is not healing, or an uncomfortable amount of pain associated with overhead activities (such as throwing, lifting and reaching) is present, a minimally invasive AC separation treatment known as arthroscopic shoulder surgery for AC repair can be performed by Dr. Millett.

Have you sustained an AC joint separation and would like information on treatment options?

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.

An AC separation treatment is an exciting new technique that allows for the repair of acute or chronic AC separations not healing with conservative measures. The surgery is performed on an out-patient basis, and full range of motion is quickly re-established within days of the procedure. During this out-patient procedure, also called the “Mumford” procedure, the end of the collarbone is removed through several tiny incisions. Once inside the shoulder, the clavicle is repaired and fixed back to its proper position. This technique is very successful for painful joints (weightlifters, arthritis, or minor separation).

Following a surgical AC separation treatment, patients will start shoulder motion under the direction of Dr. Millett and his team. Patients will be asked to wear a sling to protect the shoulder joint for several weeks following surgery. Eventually, after the ligaments heal, patients will be allowed to progressively strengthen the shoulder and discard the sling. Many patients can expect to return to sporting activities usually around 3 to 4 months following surgery.

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!!!
