Snapping Scapula Syndrome – Non-surgical options

Ross A. Hauser, MD. 

Snapping Scapula Syndrome

Over the years we have seen many patients with scapula area problems. The people we see who have been diagnosed with Snapping Scapula Syndrome come into our exam rooms and for many, the first thing they want to do is to make the “snapping” sound for us. Some patients can really make a loud noise, we have probably said “wow” on more than one occasion.

For some the snapping noise is just as much of a problem as the pain and functional problems the Snapping Scapula Syndrome is causing them. In this article we will discuss treatment options that will eliminate the snap and restore normal pain free motion.

If you have finally been diagnosed with Snapping Scapula Syndrome or are searching still for the correct diagnosis you have likely been on a journey that may include:

Your doctor may have spoke to you about “Washboard syndrome,” Scapulocostal Syndrome or Scapulothoracic Syndrome, these are also terms that can describe Snapping Scapula Syndrome and the cause of your grating, grinding, popping or snapping sensation of the scapula.

Your medical history may include all these terms and more, possibly a confusion with something going on in your shoulder. The problem to you however is that no one can figure out what is going on, your condition can be quite painful and is extremely irritating. You are constantly recommended to the same group of treatments: nonsteroidal anti-inflammatories, cortisone shots, trigger point injections, physiotherapy, chiropractic care, and surgery and you have continuous and frustrating suboptimal results.

Diagnosing snapping scapula syndrome

Above I mentioned the cervical neck facet joints and cervical radiculopathy as diagnoses in the case of shoulder instability. In the caption of this image says:

“Shoulder-cervical instability connection. Shoulder instability cause levator scapulae contraction which can increase the symptoms of cervical instability through its attachment at C1-C4. Sometimes to resolve upper cervical spine instability or shoulder instability, or both, treatments may be need in the neck and shoulder.

Controversial diagnosis

The diagnosis of Snapping Scapula Syndrome is controversial because Snapping Scapula Syndrome is considered a rare condition. Except to the people who have it.) It is basically a problem of the normal interplay and movement between the anterior (or front) of the scapula and the posterior (or back of the) chest wall.

What you may have hear at the specialist’s office as they try to pinpoint your problem:

We are going to bring in the Department of Radiology, Keck School of Medicine, University of Southern California to help us here explain what you may have heard at the specialist’s office and try to help you understand it in more common terms. This description of the Snapping Scapula Syndrome appeared in the the journal Skeletal radiology.(1)

All these terms may have been explained to you as your possible cause for your problems of:

Conservative and Arthroscopic Treatment of Snapping Scapula Syndrome

Surgery of course is that last option following an extensive course of conservative, non-surgical treatments. If you are reading this article you may have been recently diagnosed with Snapping Scapula Syndrome and you are searching for treatments or you have had Snapping Scapula Syndrome for some time and now you are searching for surgery alternatives.

For many people, conservative care options for Snapping Scapula Syndrome works very well. These people who have had great results are usually not the people we see in our office. We see the people who did not have good results, perhaps someone like yourself who is now looking for different options.

Nonsteroidal anti-inflammatory medications

Because inflammation is nearly always thought to be involved in this problem, especially if bursitis is suspected or present, one of the first things you will be suggested to is Nonsteroidal anti-inflammatory medications (NSAIDs). For some of you, NSAIDs may have helped quite a bit initially. Eventually however as pain continued and increasing doses of NSAIDs were not helpful and possibly made your pain worse, other options needed to be explored.

Physical Therapy and anti-inflammatories

For many people, physical therapy can offer a lot of benefit. You may have seen these benefits yourself. A restoration of normal scapula function. That is the movement that allows the scapula to guide over the rib cage and provide the support the shoulder needs to also move normally. If you are reading this article it is unlikely that physical therapy has benefited you as much as you would have hoped. Why and how did this happen?

One of the criteria for getting physical therapy is that the inflammation that is causing a distorted painful movement is eliminated. People do not do well in physical therapy if pain prevents them from achieving the exercises need to help their problem. So strong anti-inflammatories and cortisone injections are recommended. Sometimes a simple numbing agent is given to get the patient through their exercises if the pain is a barrier.

Once convinced the patient is ready for physical therapy, a routine that includes postural training, (stopping you from slouching), stretching and strengthening will be offered.

Physical therapy and why physical therapy may have failed you

Let’s look at a report in the Journal of Muscles Ligaments and Tendons (2) to help us understand the goals of physical therapy and why physical therapy may have failed you.

Failure of physical therapy – uncorrected instability

Patients are often very confused as to why a physical therapy program or exercise/activity program did not help their Snapping Scapula Syndrome problem as much as they thought it would. Clinicians, doctors, and therapists are equally confused. This is very typical of the patients we see. They have been to physical therapy for months and nothing seems to have improved. Many of these patients have been listening and reading about “5 great exercises to help Snapping Scapula Syndrome” to strengthen their problem areas.  These people have been told that exercise will lead to greater pain relief and an increase in mobility. So why is it not working for them, when physical therapy and exercise is so beneficial to so many others?

Loss of strength, muscle power and range of motion are clearly indicators of an impending surgical recommendation. In patients with Snapping Scapula Syndrome, where connective tissue such as the tendons that attach muscles to the bones are damaged. It is very difficult to derive benefit from strength training where resistance is needed because the tendons that help provide that resistance are weak. Physical therapy results can be improved if you strengthen and repair weakened and damaged tendon attachments. The tendon’s enthesis is that piece of tissue that attaches your muscle to the bone.  The term enthesopathy typically refers to a degenerated enthesis and this may have been discussed with you at one of your many doctor or PT visits. It is not only the tendons. It is the ligaments of the scapula region as well. These include the coracohumeral ligament and the glenohumeral ligaments. When these ligaments are damaged because of degenerative wear and tear, the bones do wander off and start floating around. They start to bang against each other in unnatural damaging contact. This can cause a bursitis to develop.

In the image below, we see the various ligaments of the shoulder.

Addressing tendons and ligaments before you consider surgery

Many people will think, “I am too far gone,” I need the surgery. So they get themselves on a waiting list and manage themselves along with painkillers, and anti-inflammatories and youtube videos on exercise. These are the very remedies that have already not been as helpful as hoped for but what else can they do until they wait for surgery? Secondly is surgery worth the wait?

Doctors from the Steadman Philippon Research Institute provide an assessment of Arthroscopic Treatment of Snapping Scapula Syndrome in the medical journal Arthroscopy.(3)

They looked at patients who underwent arthroscopic treatment for Snapping Scapula Syndrome after extensive nonoperative treatments failed. Nonoperative treatments include mainly physical therapy and anti-inflammatory medication.

Greater age, lower preoperative psychological score, and longer duration of symptoms before surgery correlated with lower postoperative outcome scores.

“high likelihood of persistent symptoms post-operatively”

Doctors at the Division of Orthopaedic Surgery, Department of Surgery, McMaster University Medical Centre in Canada wrote in the journal Knee surgery, sports traumatology, arthroscopy: (4)

“Arthroscopic management of snapping scapula syndrome yields improvement in pain, crepitus, and range of motion in a majority of patients; however, most patients experience residual symptoms. Further studies are needed to compare the outcomes of shoulder arthroscopy with other available treatment options for snapping scapula syndrome. Shoulder arthroscopy for snapping scapula can improve patients’ symptoms; however, patients must be informed about the high likelihood of persistent symptoms post-operatively.”

Treating the scapulothoracic area

In the caption of the image below: “Scapulothoracic upward motion to raise arm. The sternoclavicular and acromioclavicular joints also elevate when a person’s arm is raised.

Read more at: Sternoclavicular joint injury and instability and Chronic shoulder dislocation, subluxation and shoulder instability.

A May 2022 paper in the journal Sports Health (5) discusses the problems of diagnosis and treatment of Snapping scapula syndrome and its relationship to the  scapulothoracic joint  “Snapping scapula syndrome . . . is a commonly misdiagnosed and underreported condition of the scapulothoracic joint usually associated with painful crepitus and shoulder joint dysfunction when attempting overhead motion. . . symptoms are created by the excessive friction between the scapula and the thorax (the sternum, the thoracic vertebrae, and the ribs) with soft tissue (bursa, tendon, or muscle) entrapped between them. . .Physiotherapy and rehabilitation are the mainstay in nonoperative management of Snapping scapula syndrome and aim to address altered posture, scapular winging, or scapulothoracic dyskinesis. Scapular malposition can lead to abnormal force distribution throughout the shoulder joint, resulting in abnormal shoulder kinematics and problems with motion.”

In our experience, the best chance at a good patient outcome of this condition is when we address with the patient the underlying instability in the scapulothoracic area, which allows the scapula and ribs to move normally, without the abnormal wear and tear. At our office, we have treated many cases of scapulocostal syndrome using comprehensive dextrose Prolotherapy. We will explain this treatment below.

Physical examination showing winging of the scapula and rotator cuff muscle atrophy

The caption of the image below reads: Physical examination showing winging of the scapula and rotator cuff muscle atrophy. Winging of the scapula is evident on the left, where as obvious rotator cuff atrophy is seen on the right. This patient was shown a digital motion x-ray to have nerve compression of the left side while an MRI showed significant intrinsic shoulder pathology on the right side.

Prolotherapy treatment of snapping scapula syndrome – A non-surgical option

The image caption reads: Prolotherapy to the shoulder. The frequent injection site are demonstrated including the coracoid process, subscapularis tendon and the greater tuberosity.

Prolotherapy is an in-office injection treatment that research and medical studies have shown to be an effective, trustworthy, reliable alternative to surgical and non-effective conservative care treatments. In our opinion, based on extensive research and clinical results, Prolotherapy is superior to many other treatments in relieving the problems of chronic joint and spine pain and, most importantly, in getting people back to a happy and active lifestyle. This is why it is the Caring Medical treatment method of choice.

In this video Ross Hauser, MD, gives an introduction to our treatments for Snapping Scapula Syndrome

A summary transcript is below

The typical physical therapy approach to Snapping Scapula Syndrome is to strengthen the serratus anterior muscle and/or put the patient through a scapular stabilization exercise program. Prolotherapy treatments can make this more effective by strengthening the muscle attachments and helping to increase resistance.

In our published research in the Journal of Prolotherapy, we described a case study of a 31 year-old-female patient in our article: Treatment of Joint Hypermobility Syndrome, Including Ehlers-Danlos Syndrome, with Hackett-Hemwall Prolotherapy.

The patients came in at the suggestion of her osteopathic doctor because of the diminishing benefits manipulation was having on her pain.

The patient stated that she “has always had loose joints” and for most of her adult life has needed either chiropractic or osteopathic care to function. Her significant pain started 10 years earlier while on the rowing team at college. Her primary pain was located in the left T1-T4 (thoracic spine) area and left shoulder. A previous MRI of the thoracic area was read as normal. She had tried acupuncture, electrical stimulation, physical therapy, and various medications and manual therapies without lasting relief.

On physical examination, she had noticeable ligament laxity in multiple thoracic/rib junctions (costovertebral) and her left shoulder easily dislocated.

At the initial visit, dextrose Prolotherapy was given to her left thoracic facets and costovertebral junctions. When seen one month later, she felt 40% better and another Prolotherapy treatment was given to the same area. She was not seen again for several months and felt her thoracic pain didn’t need treatment anymore but she wanted to start treatment for her left shoulder instability.

The patient did not return for one year because of the resolution of her thoracic and shoulder pain with the previous Prolotherapy treatments. Her return visit surrounded hip pain.

Summary and can we help you?

Snapping syndromes in the body, including the scapula, are due to underlying joint instability. The scapula lies over the ribs and helps make up the shoulder joint. In snapping scapula syndrome, the snapping occurs as the muscles that move the shoulder joint contract against an unstable base and allow the scapula to rub against the ribs. The problem is not due to muscle weakness, rather, instability. This joint instability can occur where the ribs that attach to the thoracic spine, causing a rib to stick out too far. Or the instability can occur in the shoulder joint, such as from a labral tear or overstretched glenohumeral ligaments. For those with snapping scapula syndrome, once the instability is identified, Prolotherapy injections can provide good treatment outcomes.
