9 Facts About SICK Scapula that may surprise you

SICK Scapula: An Overlooked Cause of Shoulder Pain

SICK scapula or shoulder dykinesis is a form of shoulder pain created by disorganized movement of the shoulder joint.

Kinesis refers to “motion”, and the prefix “dys” describes something that is “bad, abnormal or difficult”.

So in the case of SICK scapula, athletes who repetitively use their arms for overhead motion such as throwing, swimming or swinging a racquet, are all at risk of developing this condition.

Pain may be followed by limited range of motion, and if left untreated, may develop into a more severe shoulder injury.

This article will help explain the anatomy of the shoulder, the features of SICK scapula and the treatments that can be used to correct it.

I’ll also be giving a few exercises corrections I like to start people with towards the end of the article. You can jump to it here if you don’t want to hear about anatomy and logic about scapula injuries.

Why is it Called SICK Scapula?

SICK is an acronym for the prominent features of the condition:

Scapular malposition
Inferior medial border prominence
Coracoid pain and malposition
• DysKinesis of scapular motion

SICK Scapula Syndrome

The Anatomy of the Shoulder

The scapula, more commonly referred to as the shoulder blade, is the boney structure on the upper back below the top of your shoulder and just behind the axilla.

It is a free floating structure with only one attachment to the upper body through a joint located at the end of the clavicle (or collar bone) called the acromioclavicular joint.

The long bone of the upper arm, called the humerus, sits in a small socket on the outer edge of the scapula. It is called the glenohumeral joint.

The glenohumeral joint by itself has very little stability. It relies on a set of four muscles known as the rotator cuff to provide the foundation and stability of the shoulder.

The rotator cuff muscles and their functions are as follows:

Supraspinatus which predominately stabilizes the shoulder and helps pull the arm toward the body (adduction)
Infraspinatus which helps rotate the upper arm so the palm faces up (external rotation)
Teres minor which also aids in external rotation
Subscapularis which helps elevate the arm away from the body (abduction)

In addition to the rotator cuff, there are several other muscles that are involved in shoulder stabilization and range of motion.

They too can be involved in SICK scapula:

Trapezius which help pull the scapula toward the spine (scapular retraction), upward as if “shrugging” the shoulders (scapular elevation), and down and inward toward the midback (scapular depression)

• The rhomboids which also aid in scapular retraction

Levator scapula which also aid in scapular elevation

Serratus anterior which stabilize the scapula and pull the scapula away from the spine as when the shoulders roll toward the front of the body (protraction/scapular abduction)

Pectoralis major which helps pull the arm towards the body (adduction)

How SICK Scapula Happens

Because the shoulder is capable of such a wide range of motion, a very complex and harmonious chain reaction of muscle contraction must occur for normal, painless movement.

Usually, this is the case for most of us in our daily lives.

But for those who repetitively use the shoulder in strenuous overhead activity, weakness and instability in any part of that chain reaction can lead to injury.

SICK scapula can be both a precursor to injury or the result of a previous one.

Like the parts of an engine, the muscles of the shoulder must all work together perfectly.

The repetitive overhead use causes certain muscles to weaken while others tighten.

This literally pulls the scapula away from the body, tilting and rotating out of its normal plane of movement. In turn, this puts stress on the head of the humerus as the angle of the glenohumoral joint changes.

Pain and restricted motion of the arm are the result.

Eventually, the normal, smooth movement of the scapula becomes completely distorted due to its altered position. In this state, continued intense, repetitive use greatly increases the chance of severe injury.

Therefore, if there is pain through range of motion or with exertion, it can be important to consider this diagnosis in addition to shoulder strain, as both share common characteristics, but have very different underlying causes.

SICK scapula is a biomechanics problem, while shoulder strains are muscle damage due to intense, repetitive movements that apply too much pressure to the muscle and joint.

Athletes such as swimmers, tennis players, baseball and softball players are susceptible given the nature of their sports.

SICK Scapula Symptoms and Evaluation

Pain and limitation of shoulder movement are usually the main complaints.

Because the scapula is misaligned, the affected shoulder will appear lower than the other or “dropped”. Also, the scapula will appear “winged” or protracted due to its altered position.

The top, front or outer portion of the shoulder may be painful to the touch.

A functional assessment tests for pain, strength and range of motion. It is very useful in diagnosing this condition. Imaging tests can be used if there is a history of shoulder trauma to rule out any fractures. Imaging can also help identify joint degeneration, bony impingement of the soft tissues and arthritis.

If a muscle strain is suspected, a musculoskeletal ultrasound can be used to evaluate for scar tissue, as this can also be a source of restricted shoulder movement and pain.

Treatment for SICK Scapula

The good news is there are many therapeutic options for treating SICK scapula.

The foundation of any program will most likely include RICE (Rest, Ice, Compression and Elevation) in addition to NSAIDs such as ibuprofen or naproxen.

Physical therapy, physiotherapy or working with an experienced strength and conditioning coach are all good options. These practitioners may also recommend or incorporate soft tissue manipulation techniques such as Active Release Technique or Graston Technique.

SICK Scapula Syndrome

An important part of any rehabilitation program is stretching. Many athletes fail to recognize the importance of stretching and warming up prior to activity. The presence of scar tissue in the muscle makes it more dense, less flexible and difficult to fully elongate.

Stretching helps get the most out of any strengthening regimen.

The common misconception that a tight muscle is a strong one is not only incorrect- it can lead to injury!

Sometimes, a tight muscle signifies it is weak, in constant spasm to maintain function, and on the verge of greater injury.

In SICK scapula, the pectoralis minor is usually very tight, contributing to the misalignment of the scapula. An effective stretch for this muscle is simply placing the forearm flat on a wall or doorway and then stepping forward. Stretches such as this should be incorporated into the therapeutic routine.

Eccentric rehabilitative exercises are also very helpful as they focus on strengthening the muscles and tendons involved in SICK scapula. These exercises can stimulate healing within the first six weeks, giving the best prognosis for recovery. Approximately 8-12 weeks of treatment will be needed, depending on the injury.

Steroid injections may be of use in decreasing the discomfort and in some cases, surgery is indicated in order to repair torn muscular tendons.

In summary, it is important to consider SICK scapula when there is shoulder pain. It is a diagnosis that can easily be made in certain athletes who perform overhead activities and have very specific findings on a physical exam.

Most importantly, when recognized early and treated, it can spare further advanced injury.

SICK Scapula Therapy Exercises

I commonly see people frustrated about the progress of their scapula injury. They’re normally given the basic stretches and exercises. I’ll name a few:

  • Doorway Stretch for the Pectoralis minor
  • Wall Angels
  • Foam rolling or self massage of the Pec Major and Upper Trap
  • Ice/ Heat
  • T, Y, W (face down exercises that nobody can name)

These are the most common and I personally don’t see anything wrong with them but they don’t account for the foundational structures/ regions of the shoulder blade.

Often we have to check a few things first. These are the regions I check before I give any shoulder blade specific exercises.

  • The Core & Breathing pattern to allow for a rigid trunk
  • Midback and Neck Motion Quality

If you don’t understand this you need to listen to my iTunes Podcast Session 47 with Max Shank. You’ll be blown away.

Here’s an exercise I use to warm people up through the shoulder blade… truthfully, if you don’t “press the ground away” the entire time, yes your shoulder will hurt but if you do it right, you will feel light years better. The stronger of a “post” you make the arm (and leg) the less they will hurt and more stable the shoulder blade will become, hence less singed scapula.

Here’s a video series I like to start people on with SICK Scapula. They account for the parts mentions above and are also more productive for the time we have in our day than the first list I gave.

If you have a short attention span you better get some popcorn. Some of these videos can be pretty detailed but they require full understanding and often in-person cueing to get right.

Think about it, you got like this through moving your body how YOU thought was correct. Often it just takes someone like me to bring your attention to the corrections and then you’re on your way.

In summary, it is important to consider SICK scapula when there is shoulder pain. It is a diagnosis that can easily be made in certain athletes who perform overhead activities and have very specific findings on a physical exam.

Most importantly, when recognized early and treated, it can spare further advanced injury.
