What Is The Rotator Cuff Muscle?
The rotator cuff muscles are a group of four muscles that surround the shoulder, are the: supraspinatus, infraspinatus, teres minor and subscapularis.
The four rotator cuff muscle tendons combine to form a broad, conjoined tendon, called the rotator cuff tendon, and insert onto the bone of the humeral head in the shoulder.
The humeral head is the ball side of the “ball and socket” shoulder joint; the socket is called the glenoid fossa.
Rotator Cuff Tear - Torn Rotator Cuff Symptoms
Many rotator cuff tears cause no pain nor produce any symptoms, tears are known to have an increasing incidence with increasing age.
[1] The most frequent cause of rotator cuff damage is age related degeneration and less frequently by sports injuries or trauma.
[2] Partial and full thickness tears have been found on post mortem studies and on MRI studies, in people who do not have a history of shoulder pain or symptoms
Torn Rotator Cuff Symptoms may include the following with regards to your shoulder:
You may notice a lack of range of movement. There may or may not be a degree of pain associated with your shoulder and shoulder movement.
There may be numbness and pain or stiffness that carries down the arm which is attached to the affected shoulder/rotator cuff.
There maybe pain while sleeping on the shoulder in question and stiffness. It may not even be possible to sleep on the affected shoulder.
In cases like this you should seek out the advice and proper diagnosis from a physician or therapist to confirm rotator cuff injury.
