What is a Rotator Cuff Injury?
Injury to your shoulder rotator cuff is very common shoulder injury.
What is your Rotator Cuff?
The shoulder joint is a relatively unstable ball and socket joint. It is often likened to a golf ball on a tee.
The subscapularis, supraspinatus, infraspinatus and teres minor are small muscles that stabilise and control your shoulder movement on your shoulder blade (scapula).
Collectively, these four muscles are known as the rotator cuff. Each rotator cuff muscle has a contractile muscle belly (red) and a tendon (white) that inserts into the bone (head of humerus).
Your rotator cuff muscles and tendons are vulnerable to full and partial tears, tendinopathies and impingement related disorders.
Rotator cuff injuries vary from mild tendon inflammation (tendonitis), bursitis (inflammed bursa), calcific tendonitis (bone forming within the tendon) through to partial and full thickness tendon tears, which may require surgery.
Some shoulder injuries are more common than others.
These include:
Your rotator cuff muscles hold you arm (humerus) onto your shoulder blade (scapula). Most the the rotator cuff tendons are hidden under the bony point of your shoulder (acromion), which as well as protecting your rotator cuff can also impinge into your rotator cuff structures.
The rotator cuff tendons are protected from simple knocks and bumps by bones (mainly the acromion) and ligaments that form a protective arch over the top of your shoulder.
In between the rotator cuff tendons and the bony arch is the sub-acromial bursa (a lubricating sack), which helps to protect the tendons from touching the bone and provide a smooth surface for the tendons to glide over.
However, nothing is fool-proof. Any of these structures can be injured - whether they be your bones, muscles, tendons, ligaments or bursas.
Rotator cuff impingement syndrome is a condition where your rotator cuff tendons are intermittently trapped and compressed during shoulder movements This causes injury to the shoulder tendons and bursa resulting in painful shoulder movements.
