Acromioclavicular Joint Instability—Reconstruction Indications and Techniques

Injuries to the acromioclavicular joint (i.e. AcromioClavicular Dislocation) are common and may lead to instability or degenerative changes requiring surgical intervention. The spectrum of injury ranges from sprain to disruption of the acromioclavicular and coracoclavicular ligaments, which provide horizontal and vertical stability to the distal clavicle. Most injuries are the result of direct trauma to the acromioclavicular joint. The majority of injuries can be nonoperatively managed. However, with significant disruption to the surrounding supportive structures, painful instability may result. Multiple stabilization procedures for the acromioclavicular joint have been described. Many of these techniques have fallen out of favor due to high complication rates. Common reconstruction techniques include either coracoclavicular ligament reconstruction with or without clavicle resection (i.e., modified Weaver-Dunn) or coracoclavicular stabilization (ie, with Bosworth screw) with repair or reconstruction of the coracoclavicular ligaments. The purpose of this paper is to review the basic anatomy, biomechanics, and treatment of acromioclavicular joint instability.

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!!!
