Many Rotator Cuff Surgeries May Be Unnecessary

By Pat Anson

Since I write about chronic pain and the many different treatments for it, it’s not uncommon for readers to ask if I’ve ever experienced it myself.

The answer, unfortunately, is yes. 

About 15 years ago, I started feeling a dull pain in my left shoulder that wouldn’t go away. It progressively grew worse, and my arm became so painful to move that I had trouble putting on a shirt or sleeping in the same position for more than a few hours. 

Only then did I finally see a doctor. An MRI confirmed there was a “wrinkle” in my rotator cuff,  and that the ligaments, muscles and tissue in my shoulder were inflamed. I had adhesive capsulitis, also known as a “frozen shoulder.” 

The doctor gave me a cortisone shot and prescription strength ibuprofen, and when neither of them helped, he recommended rotator cuff surgery or physical therapy. I opted for the latter. 

Everyone thinks their lived experience with pain is unique, and I’m no different. But it turns out my experience with shoulder pain is all too common and is likely a normal part of aging. 

According to a new study in JAMA Internal Medicine, almost everyone over the age of 40 will experience a rotator cuff injury.

Using MRI images, researchers in Finland studied the shoulders of over 600 people between the ages of 41 and 76. Although only 1 in 6 had complaints of shoulder pain, virtually everyone had a rotator cuff injury of some kind, ranging from a full tendon tear to age-related joint damage.

The findings challenge the value of advanced imaging like MRIs, which may be diagnosing shoulder problems that don’t need fixing — or at least don’t need to be treated with invasive injections and surgeries.

“In this population-based study, RC (rotator cuff) abnormalities were nearly universal after age 40 years and showed poor concordance with shoulder symptoms,” wrote lead author Thomas Ibounig, MD, an Orthopaedic Surgeon at Helsinki University Central Hospital.

“These findings suggest that RC abnormalities often represent normal age-related changes rather than disease and call into question the clinical value of routine imaging for atraumatic shoulder pain.”

Ibounig and his colleagues found that many people can have inflamed tendons (tendinopathy), full tendon tears (FTTs) and partial tendon tears (PTTs) in their shoulders without experiencing pain or any other symptoms. Only when they get medical imaging are the rotator cuff abnormalities found, which sets in motion a process that can lead to invasive treatments. 

About half a million rotator cuff repairs are performed annually in the United States, with the surgeries increasing at a rate of about 2% a year for patients 50-64 years of age. Their success rate is mixed, from about 90% for PTTs to as low as 50% for FTTs. Full recovery from rotator cuff surgery may take several months to a year. 

The Finnish study suggests that many of those surgeries are unnecessary and that shoulder pain should be accepted as a normal part of aging.  

“Given that tendinopathy, PTTs, and even FTTs may be incidental findings, clinicians should consider their high population prevalence when interpreting imaging results and deciding on interventions targeting these abnormalities. Reframing many of these findings as normal age-related changes rather than disease may help guide more appropriate care and reduce unnecessary interventions,” they concluded.

It took several months of physical therapy before my shoulder pain subsided. It still aches occasionally, but I no longer have the sharp stabbing pain that I used to get. And it’s no longer chronic.

I still use the stretches and exercises that I learned during physical therapy to keep my left shoulder from “freezing” again. It’s a good thing I learned how to do them, because now my right shoulder aches too. 

New Treatment Significantly Reduces ‘Frozen Shoulder’ Pain  

By Pat Anson, PNN Editor

Preliminary results from a small study show that an experimental treatment for adhesive capsulitis -- also known as “frozen shoulder” – dramatically reduces pain and quickly improves function in patients.

Frozen shoulder occurs when ligaments and connective tissues surrounding the shoulder joint become sore and inflamed. The inflammation gets so painful that many patients have difficulty using their arms. The resulting lack of use makes the shoulder joint even more stiff and inflamed – a vicious cycle that “freezes” the shoulder in place.

About 200,000 people annually in the U.S. develop frozen shoulder, mostly middle-aged adults. Several years ago, I was one of them. The pain was so bad at times, it felt like someone whacked me in the the shoulder with a baseball bat. I had trouble putting on a shirt or sleeping in the same position for more than a few hours.

Frozen shoulder is usually treated with physical therapy, massage, joint injections or pain medication, until the symptoms resolve in a few months or perhaps even years. Thankfully, that’s what happened to me. More serious cases can result in rotator cuff surgery.  

Researchers at the Vascular Institute of Virginia used a less invasive procedure called Arterial Embolization of the Shoulder (AES) to reduce blood flow into the shoulder of 16 patients with adhesive capsulitis. Physicians inserted a catheter through a pinhole-sized incision in the patients' wrists that was used to feed microscopic particles into six arteries leading into the shoulder.

"Patients with frozen shoulder are essentially told to tough it out until their symptoms improve, but considering the significant pain and decreased function many experience, we looked to determine if this treatment model of embolization, already in use in other areas of the body, could provide immediate and durable relief," said lead author Sandeep Bagla, MD, director of interventional radiology at the Vascular Institute of Virginia.

It may sound counter-intuitive, but decreasing the flow of blood into shoulder tissue significantly reduced the patients’ pain and inflammation.

"We were shocked at the profound and dramatic improvement patients experienced in pain and use of their shoulder," says Bagla. "We are early in the investigation of this treatment but are inspired by its effectiveness in reducing pain and range of motion in patients' shoulders."

The treatment was conducted on an outpatient basis and takes about one hour. Nine patients reported minor side effects such as skin discoloration.

The findings were recently presented in a research abstract during a virtual session of the Society of Interventional Radiology. The authors note that AES is still investigational and that conservative therapies for frozen shoulder should still be considered first.
