What is a Rotator Cuff?

As humans, we have a lot of movement in our shoulder that allows us to reach, climb and swim. Unfortunately, having this much movement means that the shoulder is more likely to be injured.

That’s where the rotator cuff comes in!

The rotator cuff is a group of four muscles around the shoulder that help hold the bone of the shoulder joint in its socket during movement. This prevents the shoulder from becoming dislocated.

Today we’ll discuss rotator cuff injuries as well as injuries related to and commonly associated with the rotator cuff.

Rotator Cuff Injury Symptoms

Rotator cuff injuries often present as a feeling of pain or weakness with shoulder movements, but there are some other common symptoms to keep in mind.

These include:

  • Pain creeping into the neck area or down the arm
  • Sensations of numbness or pins and needles in the arm or hand
  • Difficulty washing your hair, reaching above your head or putting on a jacket

What is Shoulder Tendonitis/Tendinosis?

Muscles are connected to bones by rope-like structures called tendons. Each of the four rotator cuff muscles has its own tendon.

When tendons become irritated due to repetitive movements or traumatic events like falls, inflammation makes the tendon feel sore and swollen.

This is called tendonitis, and it can make moving the shoulder feel painful. When tendinitis continues over a longer period of time, it is called tendinosis.

What is Shoulder Bursitis?

These are small sacks filled with liquid, similar to a water balloon, located in between structures like bones and tendons to prevent them from rubbing against each other and causing damage.

Just like with tendons, repetitive movement or trauma to the shoulder can cause inflammation of the bursa in the shoulder. This is called bursitis, a common cause of shoulder pain.

What is Shoulder Impingement?

In the shoulder joint, structures like the shoulder bursa and tendons are separated from the top of the shoulder blade by a small space.

Genetic abnormalities, repetitive movement or poor posture, can cause this space to shrink, leading to rubbing of tendons or bursa against the top of the shoulder blade during certain movements.

This is called shoulder impingement, a common cause of both tendonitis and bursitis.
