Rotator Cuff Tendon Tear
To understand what a rotator cuff tendon tear is, it is important to appreciate the role of a rotator cuff tendon. The rotator cuff tendons are a group of four individual tendons that work together as the “rotator cuff”.
Essentially the rotator cuff is a single unit but it is made up of the tendons of four muscles. They are the supraspinatus, infraspinatus, subscapularis, and teres minor.
These muscles attach to the scapula (shoulder blade), and their tendons merge together to form the rotator cuff. The rotator cuff runs over the upper end of the arm and connects to the humeral head of upper arm bone. The rotator cuff has two basic functions – arm movement and shoulder stability.
Movement - The rotator cuff muscles are the instigators of all arm movements. They are small muscles whose primary role is to get the arm moving. Once in motion other larger, surrounding muscles such as the deltoid take over.
Stability – The rotator cuff tendons work together to stabilise the shoulder joint. They grip the humeral head of the upper arm bone and hold it tight to the scapula (shoulder blade).

Why does a rotator cuff tendon tear?
The vast majority of people who suffer a tear in rotator cuff tendons are over 40 years of age. The rotator cuff tendons, like the rest of the body lose function with age.
Some of the elasticity goes and as we become less active they weaken through being underused. The body also becomes less efficient at repairing damage on a molecular level.
This can lead to tendinopathy type injuries. This weakening then becomes a cycle of gradual decay that leads to more problems.
As the rotator cuff tendon becomes weaker it is more liable to damage. This one of the major reasons why you should do some rotator cuff exercises.
Even if you have had no previous rotator cuff problems you should take action now. Strengthening the rotator cuff tendons will make it much less likely that suffer a rotator cuff tendon tear in the future. Prevention is definitely better than cure.
So, let’s look at a fairly typical scenario.
The above may be enough to cause a tear in rotator cuff tendons but there is often another complicating factor. As the cuff becomes weaker it fails to provide the stability to the shoulder.
The Humerus can “ride up” from the Glenoid Fossa and squash the rotator cuff tendons. The tendons begin to rub against the clavicle above and commonly tear as a result.
This often leads to a partial rotator cuff tendon tear. A complete rotator cuff tear is often associated with a combination of the above process and an acute episode.
Let’s say the rotator cuff is already weakened and then you suffer a fall. The tendons may not be able to take the impact of even a low impact event.
